From the smooth sounds of Sam Cooke to the dancing, acrobatic vocals of Kirk Franklin, gospel music does more than just sound sweet, it literally moves its listeners. Whether its swaying with the choirs or tapping along with the quartets, gospel is one genre of music that needs to be both seen and heard. Once narrowly defined as religious, gospel has transcended those limits to become a profound force in American music and popular culture. Black Gospel music draws heavily upon the traditional spirituals that have been passed down from the days of slavery, picking up its more driving rhythmic emphasis from blues and early jazz. Composer and singer Thomas A. Dorsey crystallized the style in 1932 with his epochal "Take My Hand, Precious Lord," and went on to compose a great many songs that later became gospel standards. The modern day gospel music experience is less than 50 years old. Gospel music is the music of African Americans and is ever changing.
