The vast majority of the inhabitants of the United States are immigrants or descendants of immigrants. This article will focus on the music of these communities and discuss its roots in countries across Africa, Europe and Asia, excluding only Native American music, indigenous and immigrant Latinos, Puerto Rican music, Hawaiian music and African American music. The music of Irish- and Scottish-Americans will be a special focus, due to their extreme influence on Appalachian folk music and other genres. These sorts of music are often sustained and promoted by a variety of ethnic organizations.

Armenia See: Music of Armenia

Following the Armenian genocide of 1915 perpetrated by the Young Turk government in Turkey, large numbers of Armenians settled in the Central Valley area of California, especially around Fresno. Of the second- and third-generation musicians from this community, Richard Hagopian became a minor star in the Armenian-American community. Alan Hovhaness used traditional Armenian music in his compositions. Daja Yavasharian is a solo violinist who performs classical music.

The ethnically Armenian heavy metal band System of a Down features Armenian melodic elements in many of their songs and has written songs dedicated to the Armenian genocide. The group is very active in promoting genocide awareness and recognition.

Cape Verde See: Music of Cape Verde

There are more Cape Verdeans outside of their homeland than there are in the island chain itself. In the United States, California and Hawaii are home to large Cape Verdean populations, but the largest concentration is in New England, especially Rhode Island and Southeastern Massachusetts. Many of these immigrants came via whaling ships in the 19th century. Cape Verdean music is most famously morna, but other genres exist and the Cape Verdean community has produced string bands like The B-29s, Notias, Augusto Abrio and the Cape Verdean Serenaders. There were also Cape Verdean big bands, including the Creole Vagabonds and the Don Verdi Orchestra. More modern musicians include Frank de Pina, Mendes Brothers (and their influential record label, MB Records), Saozinha, Creole Sextet and Rui Pina.

China See: Music of China

Chinese-American bands include Say Bok Gwai . The pop-rapper Jin has lately gained some national renown as well. The electronic group Shanghai Restoration Project has been rising through the charts in online downloadable music stores.

Czech lands See: Music of the Czech Republic

Though associated with Slovenia, Germany and Poland as well, the Czech Republic includes Bohemia, the ancestral home of polka music. Polka has a long history in the United States, and the city of Chicago, among others, had produced numerous innovations in the genre.

Eastern European Jews See: Jewish music, Eastern European music, Secular Jewish culture

Early in the 20th century, Eastern European immigrants settled across the United States. Many were Ashkenazi Jews, who brought with them their swift, eminently dance-able klezmer music. Harry Kandel, a clarinetist, stood out in the field, alongside Abe Schwartz, Naftule Brandwein and Dave Tarras.

Later, in the 1980s, a new generation of klezmer roots revivalists made innovative fusions of klezmer with punk rock and other influences. These bands include the Flying Klezmer Bulgar Band and The Klezmatics.

England

As the homeland of many of the settlers of the original Thirteen Colonies, and a major source of immigration thereafter, England's musical traditions are closely tied to those of the United States, especially Appalachian folk music. In the 1850s, there was a thriving brass band tradition in the United States, drawing on British bands formed around factory workers.

France See: Music of France

The most well-known kind of French music in the United States is that of the Cajuns of Louisiana. Cajun and Creole music has spawned many popular artists in the zydeco genre, including Clifton Chenier.

Germany See: Music of Germany

German immigrants brought with them a variety of music, waltzes, polkas and oom-pah bands among them. A German musical society of the mid-19th century formed the Seventh Regiment Band, the only exclusively regimental band of the Civil War-era and one of the most popular brass bands of the time. German bandleader Friendrich Wilhelm Wieprecht was also influential, collecting full scores for his compilation of instrumentations of popular works, für die jetzige Stimmenbesetzung. Instruments included the bassoon, contrabassoon, bass tuba, trumpet, trombone, clarinet, piccolo, oboe, French horn, saxhorn, drums and cymbal. Wieprecht was recognized at the time as a key figure in the reorganization of the Prussian military bands.

The music of the Amish, a religious community descended from German and Swiss settlers who eschew modern technology in favor of simplicity, is entirely religious, and is sung in a style that has not been widely performed in Europe for centuries.

The songs of the Pennsylvania German culture, a mixture of British, South German and other elements, are primarily German, with many based on British tunes. Pennsylvania spirituals are a well-known kind of folk hymn, most of which date to the early 19th century.

Greece See: Music of Greece and Greek folk music

Greek-American immigrant music includes styles of Greek music such as Ancient, traditional, with emphasis in Greek literature and poetry.

Some of the well-known Greek supporters and remarkable personalities of Greek immigrant music art in America are: Stamatis Spanoudakis, Nana Mouskouri, Maria Farantouri, Marinella, Yanni, Mikis Theodorakis, Vicky Leandros etc. and remarkable composers and pianists such as Manos Loïzos and Stefanos Korkolis. Until the 1930s the Greek discography was separated by two musical genres: the Greek folk music and the Elafró tragoudi (literally: "light song"). The latter was made by ensembles of singers/musicians or solo artists like Attik and Nikos Gounaris. It was the Greek version of the international popular music of that era. In the 1930s the first rebetiko recordings had a massive impact on Greek music in America. The tradition of eastern liturgical chant, encompassing the Greek-speaking world, developed in the Byzantine Empire from the establishment of its capital, Constantinople.

A big sign of the Greek immigrant music culture has left the Greek soprano Maria Kallas. Immigrant Greek music also includes music from Greek islands the Nisiotika and the famous dance Sirtaki with well-known artists like Yiannis Parios etc.

Greek music history extends far back into ancient Greece, since music was a major part of ancient Greek theater. Music genres and styles like Laïko, Hasapiko and rebetiko are also well-known. Performers include Johnny Otis and Tatiana Troyanos. Classic laïkó as it is known today, was the mainstream popular music of Greece during the 1960s and 1970s. Laïkó was dominated by singers such as Tolis Voskopoulos and Stelios Kazantzidis.

Among the most significant songwriters and lyricists of this period are George Zambetas and the big names of the Rebetiko era that where still in business, like Vassilis Tsitsanis and Manolis Chiotis. Many artists combined the traditions of éntekhno and laïkó with considerable success, such as the composers Stavros Xarchakos and Mimis Plessas.

The Pontic genre of immigrant music which is well-known from the remarkable minority of Pontians in America, retains elements of the musical traditions of ancient Greece, Byzantine music and the tradition of Caucasus. The prime instruments in Pontic music are the Pontic lyra (Kemenche), which has origins in Byzantine period and it is related closely with the Byzantine lyra and Cretan lyra. Other instruments include drums, lute, askomandoura (a type of bagpipe) and aulos.

Cretan music uses the dominant folk instrument Cretan lyra on the island as the result of immigrant music; a three-stringed bowed instrument similar to the Byzantine Lyra. It is often accompanied by the askomandoura (a type of bagpipe) and the Cretan laouto (λαούτο). The earliest documented music on Crete comes from Ancient Greece. Cretan music like most traditional Greek, began as product of ancient and Byzantine inspirations.

India

The Indian diaspora (and significant portion of other South Asian diaspora) enjoy Indian music, which includes Indian classical music and non-classical Indian music. The non-classical music has at least two categories: film music (original sound tracks) and non-film music (often called Indi-pop). The Bollywood music represents Hindi language film songs. Indian diaspora speaking non-Hindi languages enjoy music of their own languages, such as Tamil music, Bengali music, Punjabi music and so on. Fusion between popular Indian music (such as Bollywood or Bhangra music) and American music has taken place, and is popular in certain areas with high Indian American population density.

Iran See: Music of Iran or Persian Music

After the 1979 revolution, the new Iranian government banned all pop music and many other genres. Numerous Iranians, including musicians, entered into exile, many settling in the Los Angeles-area. The Iranian-American scene produced several stars in the Iranian-in-exile community, including Dariush, Ebi, Homeira, Hayedeh, Mahasti, Moein and more.

There are also many newcomers in Persian/Iranian Music who have made huge impression. Below are a list of them:

Andy Madadian, Mansour, Leila Forouhar, Shahrzad Sepanlou, Arash, Shadmehr Aghili, Jamshid, Cameron Cartio, Muhammad, Kamran & Hooman, Fereydoun, Hi-5, Shaghayegh, Shahriar and much more

Ireland

Joseph Halliday, a Dubliner, is notable for having introduced the keyed bugle in 1810. While not a technical innovation (the keyed trumpet was already known), it did become extremely popular in the burgeoning brass band tradition and inspired a whole family of instruments, the ophicleides. In the middle of the 19th century, Irish bandleader Patrick Sarsfield Gilmore was very influential, having introduced a wide range of reed instruments as well as developing instrumentation that allowed a large wind ensemble to approximate the effects of a full orchestra.

The 1960s saw the Clancy Brothers (with Tommy Makem) become minor celebrities in the United States, especially in the Irish-American community. They appeared at Carnegie Hall and on The Ed Sullivan Show. Mick Moloney’s Irish-American Music and Dance Festival has existed for over twenty years and remains an important part of the Irish-American scene.

In the eighties several high-profile Irish artists emigrated to the US, including Mary Black, Dolores Keane and Maura O'Connell. At the same time groups sprang up in America to play Irish music at a professional level. Mick Moloney founded Green Fields of America in 1977 to bring together immigrant Irish and native-born players of Irish music. Although they did not record an album until 1989, they created a ripple. The band contained several people who went on achieve international fame – Seamus Egan, Eileen Ivers and Jerry O'Sullivan. Another early Irish-American band was Cherish the Ladies formed in 1985.
