Listen to the Valse Boiteuse by my all-time favorite composer, Erno Dohnanyi, celebrating his 140th birthday today.
This is from a suite of waltzes for orchestra (each one an independent gem) arranged by the composer for two pianos. Vintage recording of the composer with Edward Kilenyi on the other piano.
This piece includes phrases of 5 beats. The joke is that it is all in 3/4 time, and to demonstrate this there is an overlaid melody in straight hemiola 3/2 time, overlaid on each two measures. In the full orchestral version it is easier to hear the 5-beat phrases in the winds, and then the second time through the 3/2 overlay in the strings.
