Folk spirituals were spontaneously created and performed in a repetitive, improvised style. The most common song structures are the call-and-response ("Blow, Gabriel") and repetitive choruses ("He Rose from the Dead"). The call-and-response is an alternating exchange between the soloist and the other singers. The soloist usually improvises a line to which the other singers respond, repeating the same phrase. Song interpretation incorporates the interjections of moans, cries, hollers etc... and changing vocal timbres. Singing is also accompanied by hand clapping and foot-stomping.
