Spiritual (music)
（重定向自Negro spiritual）
Spirituals (or Negro spirituals) are generally Christian songs that were created by African slaves in the United States. Spirituals were originally an oral tradition that imparted Christian values while also describing the hardships of slavery. Although spirituals were originally unaccompanied monophonic (unison) songs, they are best known today in harmonized choral arrangements. This historic group of uniquely American songs is now recognized as a distinct genre of music.
