American classical music is music written in the United States but in the European classical music tradition. In many cases, beginning in the 18th century, it has been influenced by American folk music styles; and from the 20th century to the present day it has often been influenced by folk, jazz, blues, Native American, and pop styles.
The earliest American classical music consists of part-songs used in religious services during Colonial times. The first music of this type in America were the psalm books, such as the Ainsworth Psalter, brought over from Europe by the settlers of the Massachusetts Bay Colony. The first music publication in English-speaking North America — indeed the first publication of any kind — was the Bay Psalm Book of 1640.
Many American composers of this period worked (like Benjamin West and the young Samuel Morse in painting) exclusively with European models, while others, such as William Billings, Supply Belcher, Daniel Read, Oliver Holden, and Justin Morgan, also known as the First New England School, developed a native style almost entirely independent of the most prestigious European models, though it drew on the practice of West Gallery music composers such as William Tans'ur and Aaron Williams. Many of these composers were amateurs, and many were singers: they developed new forms of sacred music, such as the fuguing tune, suitable for performance by amateurs, and often using harmonic methods which would have been considered bizarre by contemporary European standards. Some of the most unusual innovators were composers such as Anthony Philip Heinrich, who received some formal instrumental training but were entirely self-taught in composition. Heinrich traveled extensively throughout the interior of the young United States in the early 19th century, recording his experiences with colorful orchestral and chamber music which had almost nothing in common with the music being composed in Europe. Heinrich was the first American composer to write for symphony orchestra, as well as the first to conduct a Beethoven symphony in the United States (in Lexington, Kentucky in 1817).
