This song has no text but requires the singer to vocalise a small number of phonemes such as "uh" and "wah", without vibrato. There are some instructions given in the score for certain passages, including "like a pigeon" and "like a wild duck". The entire vocal line is constructed of only four pitches, except for a single bar near the end where a fifth pitch is used. The pianist plays by hitting the piano lid in various ways - with fingers and/or knuckles, as preferred. Click here to read more about this piece.
