Latin music

Latin music is a form of popular music played by from Latin America. For practical purposes that includes the Spanish-speaking Caribbean. Much Latin music is accompanied by song (singing) in Spanish.
Latin music is a part of world music, which is the study of popular and traditional music in all countries. Part of the story is also the influence of Latin music in other parts of the world, especially North America.
In discussing Latin music these themes are important:
For example, differences in the music of Peru from that of Brazil are influenced or caused by such differences:
The influence of Europe.
The influence of Europe, and in particular Spain, to Latin music is as follows:
The influence of Africa.
The influence of Africa comes mostly from slaves who originally belonged to the Yoruba, Dahomey and Congo peoples. Its importance in a Latin country varies according to whether many slaves were brought to that country hundreds of years ago. The freeing (liberation) of slaves took place at various times from the middle to the end of the 19th century. In Latin music its influence was:
Influence of indigenous peoples.
West of the Andes, the music is clearly influence by the indigenous Indian peoples. The panpipes and flutes of Peru are distinctive, as is their most popular rhythms. In Ecuador forms of the flute occur, but most of the music is influenced by the European waltz (as the "pasillo") and by various Afro-Latin styles from the Caribbean. Chile has the "cueca", introduced in 1824. It was the "most popular air of Chile". Despite this, the influence of the indigenous Indian peoples on Latin music is much less noticeable than the influence of European and African music. There are dozens of folk rhythms which survive, but usually they have had had little or no effect outside their particular locale, whereas the influence of the Spanish and African peoples is seen almost everywhere. In Argentina, the famous tango uses a rhythmical device known as the "cinquillo". This is a syncopated rhythm similar to that in the Cuban habanera. Syncopation and polyrhythms are unmistakable signs of Africa. Argentine music has a number of folk tunes and rhythms of Indian origin, but the tango is dominant and the other rhythms are not.
Latin Music in North America.
Lydia Mendoza (19162007), a singer of Mexican descent, became the first American-born Hispanic to record a song in Spanish (1928). Hispanics recording music was rare during the early 1900s. In 1960s, Tejano music (in Southern United States, Mexico), Spanish folk (in Spain), salsa (in Puerto Rico), cumbia (in South America), and bachata (in Dominican Republic) were the most popular forms of Latin music at the time.
Latin music became very popular in North America and the United States in the 1940s, 1950s and 1960s, especially mambo, cha-cha-cha, Boogaloo and Latin soul. The popular television program I Love Lucy (1951-57) featured the character Ricky Ricardo, who was the bandleader of a Cuban orchestra in New York. 
In the 1970s, bolero became a popular music genre in Puerto Rico. Puerto Rican singer Hector Lavoe became one of its important musicians. In the United States, many Hispanics were discriminated against for speaking Spanish. Because of this, many children and young adults favored English music such as rock and roll and tried not to speak Spanish outside of their home. In the 1980s, Latin music started becoming popular again. American music magazine, "Billboard" added several Latin music-categories. These include Top Latin Albums, Regional Mexican Albums, Tropical Albums and the Latin Pop Albums chart. Because of this, younger generations became interested in recording Latin music. During the late 1980s, freestyle music became a popular Latin music genre. Freestyle music was rarely recorded in Spanish.
In the 1990s, artists including Selena, Gloria Estefan, Luis Miguel, and Thalía became popular in this decade. They helped Latin music and recording Latin music popular for young children and adults. Selena became the most popular Latin artist of the United States in 1995, when she was murdered at 23. She became the first and only Latin artist to peak an album that contained mostly Spanish music at number one on the "Billboard" 200 chart. At the time of her death, she was competing with Michael Jackson and Janet Jackson with her album "Dreaming of You" (1995) which sold 3,000,000 copies its first year. Enrique Iglesias, Shakira, Marc Anthony, Ricky Martin, and Jennifer Lopez became popular in the mid and late 1990s.
In the 2000s, Latin music began to see a decrease of music sales. Tejano music became less popular, although the "Queen of Tejano music", Selena became the "Top Latin Artist of the Decade" by "Billboard" magazine in 1999. Shakira, Ricky Martin, and Jennifer Lopez continued to become more popular and had number one singles and albums in the "Billboard" 200. Marc Anthony, Aventura, Don Omar, and Enrique Iglesias remained popular in the Latin scene. In the 2010s, Prince Royce, Pitbull, Romeo Santos, and Wisin &amp; Yandel became popular during this decade. Jennifer Lopez, Ricky Martin, and Shakira crossover into English music with some Spanish releases. In the 2010s, bachata music became popular because of Prince Royce and Romeo Santos. As of 2012, Selena remains the best-selling Latin artist with 60,000,000 copies sold worldwide. Jennifer Lopez is second with 55,000,000 copies sold worldwide.
