Singing and Dancing

Singing and Dancing is a 20-minute-long piece split into two large parts, the first part concerned with singing, or song-like music, and the second part concerned with dancing, or dance-like music.
The first part is slow and austere, consisting of not much more than a very simple sequence of chords, out of which a little melody emerges after a while. The second part is lively and energetic. It is basically made up of a bouncy one-bar phrase, which is repeated over and over again, each time in a slightly different way. As the music unfolds, this repeated phrase is successively lengthened.
At the very end of the piece, elements from the first and second parts are briefly combined.
