"Magnesium sulfate (Magnesium sulphate in British English) is a chemical compound, a salt with the formula , consisting of magnesium cations (20.19% by mass) and sulfate anions . It is a white crystalline solid, soluble in water but not in ethanol. Magnesium sulfate is usually encountered in the form of a hydrate , for various values of n between 1 and 11. The most common is the heptahydrate , known as Epsom salt, which is a household chemical with many traditional uses, including bath salts. The main use of magnesium sulfate is in agriculture, to correct soils deficient in magnesium (an essential plant nutrient). The monohydrate is favored for this use; by the mid-1970s, its production was 2.3 million tons per year. The anhydrous form and several hydrates occur in nature as minerals, and the salt is a significant component of the water from some springs. Hydrates Magnesium sulfate can crystallize as several hydrates, including: * Anhydrous, ; unstable in nature, hydrates to form epsomite.https://www.mindat.org/min-40082.html * Monohydrate, ; kieserite, monoclinic. * or . * Dihydrate, ; orthorhombic. * or . * Trihydrate, . * Tetrahydrate, ; starkeyite, monoclinic. * Pentahydrate, ; pentahydrite, triclinic. * Hexahydrate, ; hexahydrite, monoclinic. * Heptahydrate, ("Epsom salt"); epsomite, orthorhombic. * Enneahydrate, , monoclinic. * Decahydrate, . * Undecahydrate, ; meridianiite, triclinic. As of 2017, the existence of the decahydrate apparently has not been confirmed. All the hydrates lose water upon heating. Above 320 °C only the anhydrous form is stable. It decomposes without melting at 1124 °C into magnesium oxide (MgO) and sulfur trioxide (SO3). =Heptahydrate (Epsom salt)= The heptahydrate takes its common name "Epsom salt" from a bitter saline spring in Epsom in Surrey, England, where the salt was produced from the springs that arise where the porous chalk of the North Downs meets non-porous London clay. The heptahydrate readily loses one equivalent of water to form the hexahydrate. =Monohydrate= The monohydrate can be prepared by heating the hexahydrate to approximately 150 °C. Further heating to approximately 300-320 °C gives anhydrous magnesium sulfate. =Undecahydrate= The undecahydrate , meridianiite, is stable at atmospheric pressure only below 2 °C. Above that temperature, it liquefies into a mix of solid heptahydrate and a saturated solution. It has an eutectic point with water at −3.9 °C and 17.3% (mass) of MgSO4. Large crystals can be obtained from solutions of the proper concentration kept at 0 °C for a few days. At pressures of about 0.9 GPa and at 240 K, meridianiite decomposes into a mixture of ice VI and the enneahydrate =Enneahydrate= The enneahydrate was identified and characterized only recently, even though it seems easy to produce (by cooling a solution of and sodium sulfate in suitable proportions). The structure is monoclinic, with unit-cell parameters at 250 Ka= 0.675 nm, b = 1.195 nm, c = 1.465 nm, β = 95.1°, V = 1.177 nm3 with Z = 4. The most probable space group is P21/c. Magnesium selenate also forms an enneahydrate , but with a different crystal structure. Natural occurrence Magnesium sulfates are common minerals in geological environments. Their occurrence is mostly connected with supergene processes. Some of them are also important constituents of evaporitic potassium-magnesium (K-Mg) salts deposits. Bright spots observed by the Dawn Spacecraft in Occator Crater on the dwarf planet Ceres are most consistent with reflected light from magnesium sulfate hexahydrate. Almost all known mineralogical forms of MgSO4 are hydrates. Epsomite is the natural analogue of "Epsom salt". Meridianiite, MgSO4·11H2O, has been observed on the surface of frozen lakes and is thought to also occur on Mars. Hexahydrite is the next lower (6) hydrate. Three next lower hydrates—pentahydrite, starkeyite, and especially sanderite are rare. Kieserite is a monohydrate and is common among evaporitic deposits. Anhydrous magnesium sulfate was reported from some burning coal dumps. Preparation Magnesium sulfate is usually obtained directly from dry lake beds and other natural sources. It can also be prepared by reacting magnesite (magnesium carbonate, ) or magnesia (oxide, ) with sulfuric acid. Another possible method is to treat seawater or magnesium- containing industrial wastes so as to precipitate magnesium hydroxide, and react the precipitate with sulfuric acid. Uses =Medical= Magnesium sulfate is used both externally (as Epsom salt) and internally. The main external use is the formulation as bath salts, especially for foot baths to soothe sore feet. Such baths have been claimed to also soothe and hasten recovery of muscle pain, soreness, or injury. However, these claims have not been scientifically confirmed. The main benefit of the salt is cosmetic: it prevents the temporary skin wrinkling caused by prolonged immersion in plain water. It is also the usual component of the solution used in isolation tanks. In the UK, a medication containing magnesium sulphate and phenol, called "drawing paste", is claimed to be useful for small boils or localised infections, and removing splinters. Internally, magnesium sulfate may be administered by oral, respiratory, or intravenous routes. Internal uses include: replacement therapy for magnesium deficiency, treatment of acute and severe arrhythmias, as a bronchodilator in the treatment of asthma, and preventing eclampsia. =Agriculture= In agriculture, magnesium sulfate is used to increase magnesium or sulfur content in soil. It is most commonly applied to potted plants, or to magnesium-hungry crops, such as potatoes, tomatoes, carrots, peppers, lemons, and roses. The advantage of magnesium sulfate over other magnesium soil amendments (such as dolomitic lime) is its high solubility, which also allows the option of foliar feeding. Solutions of magnesium sulfate are also nearly pH neutral, compared with alkaline salts of magnesium as found in limestone; therefore, the use of magnesium sulfate as a magnesium source for soil does not significantly change the soil pH. Magnesium sulfate was historically used as a treatment for lead poisoning prior to the development of chelation therapy, as it was hoped that any lead ingested would be precipitated out by the magnesium sulfate and subsequently purged from the digestive system. This application saw particularly widespread use among veterinarians during the early-to-mid 20th century; Epsom salt was already available on many farms for agricultural use, and it was often prescribed in the treatment of farm animals which inadvertently ingested lead. =Food preparation= Magnesium sulfate is used as a brewing salt in making beer. It may also be used as a coagulant for making tofu. =Chemistry= Anhydrous magnesium sulfate is commonly used as a desiccant in organic synthesis due to its affinity for water and compatibility with most organic compounds. During work-up, an organic phase is treated with anhydrous magnesium sulfate. The hydrated solid is then removed with filtration, decantation or distillation (if the boiling point is low enough). Other inorganic sulfate salts such as sodium sulfate and calcium sulfate may be used in the same way. =Construction= Magnesium sulfate is used to prepare specific cements by the reaction between magnesium oxide and magnesium sulfate solution, which are of good binding ability and more resistance than Portland cement. This cement is mainly adopted in the production of lightweight insulation panels. Weakness in water resistance limits its usage. Magnesium (or sodium) sulfate is also used for testing aggregates for soundness in accordance with ASTM C88 standard, when there are no service records of the material exposed to actual weathering conditions. The test is accomplished by repeated immersion in saturated solutions followed by oven drying to dehydrate the salt precipitated in permeable pore spaces. The internal expansive force, derived from the rehydration of the salt upon re-immersion, simulates the expansion of water on freezing. =Aquaria= Magnesium sulfate heptahydrate is also used to maintain the magnesium concentration in marine aquaria which contain large amounts of stony corals, as it is slowly depleted in their calcification process. In a magnesium-deficient marine aquarium, calcium and alkalinity concentrations are very difficult to control because not enough magnesium is present to stabilize these ions in the saltwater and prevent their spontaneous precipitation into calcium carbonate. Double salts Double salts containing magnesium sulfate exist. There are several known as sodium magnesium sulfates and potassium magnesium sulfates. A mixed copper-magnesium sulfate heptahydrate (Mg,Cu)SO4·7H2O was recently found to occur in mine tailings,and has been given the mineral name alpersite. See also * Calcium sulfate References A.

"Traditional Indonesian Musical Instrument The music of Indonesia demonstrates its cultural diversity, the local musical creativity, as well as subsequent foreign musical influences that shaped contemporary music scenes of Indonesia. Nearly thousands of Indonesian islands having its own cultural and artistic history and character.Indonesian Geography http://countrystudies.us/indonesia/28.htm This results in hundreds of different forms of music, which often accompanies by dance and theatre. The musics of Java, Sumatra, Bali, Flores and other islands have been documented and recorded, and research by Indonesian and international scholars is ongoing. The music in Indonesia predates historical records, various Native Indonesian tribes often incorporate chants and songs accompanied with musics instruments in their rituals. Today the contemporary music of Indonesia is popular in the region, including neighbouring countries; Malaysia, Singapore and Brunei.MyIndo KC Ismail: Muzik Indonesia lebih progresif dari muzik Malaysia (in Malay) Traditional regional musics and songs of Indonesia natively compromises of strong beat and harmony type musics with strong influence of Indian and Malay classical music. The influence is strongly visible in the traditional popular music genre of Dangdut. Musical instruments The Sundanese Degung gamelan performance in Museo Nacional de las Culturas Mexico, Indra Swara group. Gamelan xylophone solo. The musical identity of Indonesia as we know it today began as the Bronze Age culture migrated to the Indonesian archipelago in the 2nd-3rd century BC.Asia Sound Traditional musics of Indonesian tribes often uses percussion instruments, especially gendang (drums) and gongs. Some of them developed elaborate and distinctive musical instruments, such as sasando string instrument of Rote island, angklung of Sundanese people, and the complex and sophisticated gamelan orchestra of Java and Bali. Indonesia is the home of gong chime, there are many variants across Indonesia, especially in Java and Bali. = Gamelan = The gamelan performance in the palace of Surakarta Sunanate. The most popular and famous form of Indonesian music is probably gamelan, an ensemble of tuned percussion instruments that include metallophones, drums, gongs and spike fiddles along with bamboo flutes. Similar ensembles are prevalent throughout Indonesia and Malaysia, however gamelan is originated from Java, Bali, and Lombok. In the Central Java, gamelan is intricate and meticulously laid out. The central melody is played on a metallophone in the centre of the orchestra, while the front elaboration and ornamentation on the melody, and, at the back, the gongs slowly punctuate the music. There are two tuning systems. Each gamelan is tuned to itself, and the intervals between notes on the scale vary between ensembles. The metallophones cover four octaves, and include types like the slenthem, demung, saron panerus and balungan. The soul of the gamelan is believed to reside in the large gong, or gong ageng. Other gongs are tuned to each note of the scale and include ketuk, kenong and kempul. The front section of the orchestra is diverse, and includes rebab, suling, siter, bonang and gambang. Male choruses (gerong) and female (pesindhen) solo vocalists are common. With the arrival of the Dutch colonisers, a number system called kepatihan was developed to record the music. Music and dance at the time were divided into several styles based on the main courts in the area—Surakarta, Yogyakarta, Pakualaman and Mangkunegaran. Gamelan from eastern Java is less well-known than central or western parts of the island. Perhaps most distinctive of the area is the extremely large gamyak drum. In West Java, formerly Sunda, has several types of gamelan. Gamelan Degung, gamelan salendro and tembang sunda are three primary types. The Osing Javanese minority in eastern Java are known for social music for weddings and other celebrations called gandrung, as well as angklung, played by young amateur boys, which is very similar to Balinese gamelan. = Kulintang = Kolintang or kulintang is a bronze and wooden percussion instrument native to eastern Indonesia and also The Philippines. In Indonesia it is particularly associated with Minahasa people of North Sulawesi, however it also popular in Maluku and Timor. = Talempong = Talempong performance Talempong is a traditional instrument of the Minangkabau of West Sumatra. The shape is almost the same as the bonang instrument in the gamelan device. Talempongs can be made of brass, but some are made of wood and stone. Talempongs are played by being hit using a wooden rod or a stick. = Angklung = The student angklung performance Angklung is a bamboo musical instrument native to Sundanese people of West Java. It is made out of bamboo tubes attached to a bamboo frame. The tubes are carved so that they have a distinctive resonant pitch when being vibrated. Each angklung only plays one note. = Kacapi suling = SambaSunda music performance, featuring traditional Sundanese music instruments such as kecapi, suling, and kendang. Kacapi suling is a type of instrumental music that is highly improvisational and popular in parts of West Java that employs two instruments, kacapi (zither) and suling (bamboo flute). It is related to tembang sunda. = Sasando = Sasando is a plucked string instrument native of Rote island of East Nusa Tenggara. The parts of sasando are a bamboo cylinder surrounded by several wedges where the strings are stretched, surrounded by a bag-like fan of dried lontar or palmyra leaves (Borassus flabellifer), functioned as the resonator of the instrument. = Tapanuli ogong = Musical performance from Tapanuli area of North Sumatra. Tapanuli ogong is a form of dance music played with a type of lute, trumpet and flute. Genres The diverse world of Indonesian music genres was the result of the musical creativity of its people, and also the subsequent cultural encounters with foreign musical influences into the archipelago. Next to distinctive native form of musics, several genres can traces its origin to foreign influences; such as gambus and qasidah from Middle Eastern Islamic music, keroncong from Portuguese influences, and dangdut with notable Hindi music influence. = Folk music = Indonesian regional folk pop musics reflects the diversity of Indonesian culture and Indonesian ethnicity, mostly use local languages and a mix of western and regional style music and instruments. Indonesian folk music is quite diverse, and today embraces pop, rock, house, hip hop and other genres, as well as distinct Indonesian forms. There are several kinds of "ethnic" pop music, generally grouped together as Pop Daerah (regional pop). These include Pop sunda, Pop Minang, Pop Batak, Pop Melayu, Pop Ambon, Pop Minahasa and others. Other than featuring the legacy of Lagu Daerah (regional traditional songs) of each regional cultures, the musician might also create some new compositions in their own native language. = Tembang Cianjuran Sunda = Tembang sunda, also called "seni mamaos cianjuran", or just cianjuran, is a form of sung poetry which arose in the colonial-era of Cianjur. It was first known as an aristocratic art; one cianjuran composer was R.A.A. Kusumahningrat (Dalem Pancaniti), ruler of Cianjur (1834–1862). The instruments of Cianjuran are kacapi indung, kacapi rincik and suling or bamboo flute, and rebab for salendro compositions. The lyrics are typically sung in free verse, but a more modern version, panambih, is metrical. It is usually the drums. = Jaipongan = Jaipongan dance performance Jaipongan is a very complex rhythmic dance music from the Sundanese people of western Java. The rhythm is liable to change seemingly randomly, making dancing difficult for most listeners. Its instruments are entirely Sundanese, completely without imported instruments. It was invented by artists like Gugum Gumbira after Sukarno prohibited rock and roll and other western genres in the 1960s. = Gambus = Gambus literally means oud, referring to a type of lute or 12-string pear-shaped guitar, is the Middle-Eastern-derived Islamic vocal and instrumental music. These traditions began to be incorporated throughout many areas of Indonesia by the 16th century. = Qasidah modern = Qasidah is an ancient Arabic word for religious poetry accompanied by chanting and percussion. Qasidah modern adapts this for pop audiences. It is used to denote a type of orchestra and the music it plays, believed to be introduced by Muslim settlers from Yemen. Qasidah modern were derived from Islamic pop, adding local dialects and lyrics that address Indonesian contemporary issues. Though popular among Arabs in Indonesia, it has gained little popularity elsewhere. One of the oldest qasidah modern musical groups in Indonesia is Nasida Ria. The contemporary form of Islamic Middle Eastern-influenced music in Indonesia is exemplified by the band Debu, that feature a sufism approach on music to spread their message. = Kroncong = Keroncong singer, Waldjinah in a kroncong performance at the 55th Tong Tong Fair at The Hague in 2013. Kroncong (alternative spelling: Keroncong) has been evolving since the arrival of the Portuguese, who brought with them European instruments. By the early 1900s, it was considered a low-class urban music. This changed in the 1930s, when the rising Indonesian film industry began incorporating kroncong. And then even more so in the mid- to late 1940s, it became associated with the struggle for independence. Perhaps the most famous song in the kroncong style is "Bengawan Solo", written in 1940 by Gesang Martohartono, a Solonese musician. Written during the Japanese Imperial Army occupation of the island in World War II, the song (about the Bengawan Solo River, Java's longest and most important river) became widely popular among the Javanese, and then later nationally when recordings were broadcast over the local radio stations. The song also became quite popular with the Japanese soldiers, and when they returned to Japan at the end of the war re-recordings of it (by Japanese artists) became best-sellers. Over the years it has been re-released many times by notable artists, mainly within Asia but also beyond (like Anneke Grönloh), and in some places it is seen as typifying Indonesian music. Gesang himself remains the most renowned exponent of the style, which although it is seen now as a somewhat starchy and "dated" form is still popular among large segments of the population, particularly the older generation. After World War II and during Indonesian National Revolution (1945–1949) and afterwards, kroncong was associated with patriotism, since many of Indonesian poets and patriotic songs authors uses kroncong and somewhat jazz fusion as the genre of their works. The patriotic theme and romantic wartime romance was obvious in the works of Ismail Marzuki, such as "Rayuan Pulau Kelapa", "Indonesia Pusaka", "Sepasang Mata Bola", "Keroncong Serenata" and "Juwita Malam". These patriotic songs can be sung in hymn or even in orchestra, but most often was sung in kroncong style known as kroncong perjuangan (struggle kroncong). The kroncong divas; Waldjinah, Sundari Sukoco and Hetty Koes Endang, was instrumental in reviving the style in the 1980s. = Langgam Jawa = There is a style of kroncong native to Surakarta (Solo) called langgam jawa, which fuses kroncong with the gamelan seven-note scale. = Gambang kromong = Gambang kromong, a music performed on melodic percussions and brass, is native of the Indonesian capital of Jakarta. Early in the 20th century, kroncong was used in a type of theatre called Komedi Stambul; adapted for this purpose, the music was called gambang kromong. Gambang kromong is quite prevalent in Betawi culture of Jakarta. = Tanjidor = Tanjidor is a traditional Betawi musical ensemble of Jakarta. The instruments used are almost the same as the drum band, usually consists of tuba or sousaphone, trumpet, clarinet, tambourine and drums. The term tanjidor was derived from Portuguese tanger (playing music) and tangedor (playing music outdoors), subsequently adopted in Betawi language as tanji (music). Other than Jakarta, tanjidor musical ensamble is also can be found in Pontianak, West Kalimantan. = Dangdut = A dangdut performance Dangdut is a popular traditional music genre of Indonesia which is partly derived of Indian, Arab, and Malay music. It consists of melodious and harmonical music with the main Tabla as the percussion beat especially in the classical dangdut versions. It was originally an Indonesian dance music that has spread throughout Southeast Asia, became the dominant pop style in the mid-1970s. Famous for its throbbing beat and the slightly moralistic lyrics that appeal to youth, dangdut stars dominate the modern pop scene. However dangdut—especially performed by female singers—also often featuring suggestive dance movements and naughty lyrics to appeal the larger audience. This development was strongly opposed by the conservative older generation dangdut artist. Dangdut is based around the singers, and stars include Rhoma Irama and Elvy Sukaesih (the King and Queen of Dangdut), Mansyur S., A. Rafiq, Camelia Malik and Fahmy Shahab; along with Cici Paramida, Evie Tamala, Inul Daratista, Julia Perez and Dewi Perssik from younger generation. = Campursari = A musical fusion style of traditional Javanese music and dangdut that prevalent in Javanese cultural sphere, mainly Central Java, Yogyakarta and East Java. There is also Sundanese version of campursari prevalent in Bandung region of West Java. Perhaps its greatest current artist is Didi Kempot. Contemporary music The contemporary music of Indonesia is diverse and vibrant. Throughout its history, Indonesian musicians were open to foreign influences of various music genres of the world. American jazz was heavily marketed in Asia, and foxtrots, tangos, rumbas, blues and Hawaiian guitar styles were all imitated by Indonesian musicians.National Geographic Indonesian Pop Music As the result, various genres were developed within Indonesian music frame: Indonesian pop, rock, jazz, and hip hop. Indonesian music also plays a vital role in the Indonesian creative pop culture, especially as the soundtracks or theme songs of Indonesian cinema and sinetrons (Indonesian TV drama). Indonesian film Badai Pasti Berlalu (1977) were also produced successful soundtrack hit with same title in the same year, the soundtrack was remade in 1999 with Chrisye as the main singer and rendered by Erwin Gutawa in orchestra style. In 2007 the film was remade again with a new soundtrack that still features same songs performed by younger generation artist. Another popular Indonesian coming of age teen movie Ada Apa Dengan Cinta (2002) also produced successful soundtrack hits with most songs written and performed by Melly Goeslaw. Today the Indonesian music industry enjoys nationwide popularity. Thanks to common culture and intelligible languages between Indonesian and Malay, Indonesian music enjoyed regional popularity in neighbouring countries such as Malaysia, Singapore and Brunei. However, the overwhelming popularity of Indonesian music in Malaysia had alarmed the Malaysian music industry. In 2008 Malaysian music industry demanded the restriction of Indonesian songs on Malaysian radio broadcasts.Malaysian music industry wants Indonesian songs restricted = Orchestra = Western classical music reached Indonesia in the era of Dutch East Indies as early as the 18th century, but it was enjoyed only by a handful of wealthy Dutch plantation owners and officers in elite social clubs and ballrooms such as Societeit Harmonie in Batavia and Societeit Concordia in Bandung. De Schouwburg van Batavia (today Gedung Kesenian Jakarta) was designed as a concert hall in the 19th century. Classical music has been restricted to the refined, wealthy and educated high-class citizen, and never penetrated the rest of the population during the East Indies colonial era. The type of western-derived music that transcended the social barrier at that time was Kroncong, known as lower-class music. An amateur group called Bataviasche Philharmonic Orchestra was established in Dutch colonial times. It became the NIROM orchestra when the radio broadcasting station Nederlandsch-Indische Radio Omroep Maatschappij was born in 1912. Today it is known as Jakarta Symphony Orchestra that has existed in the country's musical world for almost a century through its changing formats to suit prevailing trends and needs. In 1950, a merger of the Cosmopolitan Orchestra under Joel Cleber and the Jakarta Studio Orchestra under Sutedjo and Iskandar appeared as the Djakarta Radio Orchestra under Henkie Strake for classical repertoires, and the Jakarta Studio Orchestra led by Syaiful Bachri specialised in Indonesian pieces. In 2010 Jakarta Symphony Orchestra staged a comeback after a fairly long absence.Jakarta Symphony Orchestra returns In the 1960s to 1980s classical music in Indonesia aired mainly by the national radio broadcasting service Radio Republik Indonesia (RRI) and the national TV station Televisi Republik Indonesia (TVRI) through their programs. During these decades, the classical orchestra mainly developed in Universities as an extracurricular activity for students which included choir. In the 1990s the group of professional symphony orchestra start to take form, notably The Twilite Orchestra led by Adie MS, was founded in June 1991, initially an ensemble with 20 musicians. The ensemble has developed since then into a full symphonic orchestra with 70 musicians, a 63-member Twilite Chorus, and a repertoire that ranges from Beethoven to The Beatles.Orchestra The orchestra has played a role in promoting Indonesian music, especially in the preservation of national songs by Indonesian composers and traditional songs. Aided by the Victorian Philharmonic Orchestra with the Twilite Chorus, Addie MS re-recorded the Indonesian national anthem, Indonesia Raya, by WR Supratman in its original orchestral arrangement by Jos Cleber, as well as other Indonesian popular national songs in the album Simfoni Negeriku. The Indonesian composer who is considered most prominent and well-known worldwide in the classical / contemporary music is Ananda Sukarlan (born 1968), with many orchestral works, chamber and instrumental. His most celebrated works are a series of virtuosic Rapsodia Nusantara for piano solo, with musical motifs based on Indonesian folktunes. He has written works for musicians such as from the Boston Symphony Orchestra, violinist Midori Goto etc., and his works are widely performed worldwide Today, major cities like Jakarta, Bandung, Yogyakarta, Surabaya, Medan and Batam are no strangers to orchestral music, with their own symphony groups. Jakarta, for instance, has its Nusantara Symphony Orchestra, the Twilite Orchestra and the Jakarta Chamber Orchestra. Indonesia also has many patriotic songs that are used, played, and memorized by the population, some of these national songs are used during the colonial era of the Dutch East Indies, Japanese Occupation, and today Indonesia. Many of these songs have been recorded using orchestral recordings on different albums such as 'Simfoni Negeriku' conducted by Addie MS. List of Indonesian national songs. = Pop = JKT48 performs at Jakarta–Japan Matsuri 2012. Peterpan, one of Indonesia's popular bands Indonesian pop music today, known simply as "pop Indonesia" is heavily influenced by trends and recordings from America,National Geographic Indonesian Pop Music Britain, Japan, and Korea. Although influences ranging from American pop, British pop, and also Asian J-pop and K-pop are obvious, the Indonesian pop phenomena is not completely derivative; it expresses the sentiments and styles of contemporary Indonesian life. Koes Bersaudara later formed as Koes Plus is considered as one of the pioneer of Indonesian pop and rock and roll music in the 1960s and 1970s. The American and British music influences were obvious in the music of Koes Bersaudara, The Beatles were known to be the main influences of this band. Several Indonesian pop and ballad singers were survived through decades and become Indonesian music legends, such as Iwan Fals and Chrisye. One of the most influential Indonesian singers in pop music scene, especially during early 2000, is Agnes Monica, who had later known as Agnez Mo. Today, the popular bands include Peterpan, Radja, Gigi, Padi, Dewa 19, Sheila on 7, D'Masiv and Nidji, all of which tour regularly in Indonesia, Singapore and Malaysia and are featured on MTV Asia. Some of Indonesian pop bands are rekindled with their Malay roots and revived a genre called "Band Pop Melayu" (Pop Malay Band) and popular in the late 2000s. The pop Malay bands include ST 12. Indonesian pop music from the 1980s and 1980 are commonly referred to as "Indonesian city pop", due to their perceived similarities to the Japanese genre. The Japanese city pop itself gained popularity among youngsters and amateur musicians in the late 2010s via the Internet. The most recent foreign influences on Indonesian pop music are influenced from J-pop and K-pop. Several bands such as J-Rocks emulate Japanese and Korean pop culture. Girl groups are also spreading among boy bands, such as 7icons and Cherrybelle, as well as JKT48 which is an offshoot of the Japanese AKB48. = Rock = Just like pop music, Indonesian rock scene also was heavily influenced by the development of rock music in America. The most influential Indonesian rock bands was probably Panbers that was popular in the 1970s and 1980s. In the late 1980s to mid-1990s several female rock singers popularly known as "Lady Rockers" were famous in Indonesia, such as Nicky Astria and Anggun who started her career in as a pop-rock singer in Indonesia before moving to France and pursue her international career. Other notable rock bands include Slank and Jamrud. Metal bands also exist, such as the metalcore band Killing Me Inside. = Jazz fusion = Some of Indonesian musicians and bands were exploring the jazz music. Notable Indonesian jazz musicians include Jack Lesmana, Benny Likumahuwa, Benny Mustafa, Maryono, Bubi Chen Maliq & D'Essentials. Various other groups fuse contemporary westernised jazz fusion music with the traditional ethnic music traditions of their hometown. In the case of Krakatau and SambaSunda, the bands from West Java, the traditional Sundanese kacapi suling and gamelan orchestra is performed alongside drum set, keyboard and guitars. The Jakarta International Java Jazz Festival is performed annually. The latest development of Jazz in Indonesia reflected with many Jazz Festivals being held every year. =Notable contemporary artists= *Gesang *Titiek Puspa *Guruh Sukarnoputra *Gombloh *Bing Slamet *Benyamin Sueb *Chrisye *Harry Roesli (1950s–1970s) *Ebiet G.
