According to “Humorous reflections on laughing records” by Abigail Cooke (ARSC journal 32/2 [winter 2001], pp. 232–242, three types of sound recordings involving laughter were produced between 1904 and 1923: (1) laughing songs, in which stylized laughter is integrated into the song; (2) spoken comedy routines with laughing audiences; and (3) laughing records, in which apparently genuine laughter spirals out of control.
The classic model for the latter genre, The Okeh laughing record (Okeh, 1922)—which may have originated in a real situation where the recording engineer continued to record a botched session—begins with a man playing a slow, melancholy cornet solo that is quickly interrupted by a woman’s giggle. He continues to play, but she is unable to control herself, and soon is laughing aloud; this causes him to flub a note and join her in laughing, occasionally attempting to continue playing, until the two are utterly hysterical.
