“Sotto voce” is first and foremost a poem by Louisa Siefert (19th century). The title is very suggestive for singers and seems to have only been made to be set to music.
The text is so musical that you only have to say it, or even whisper it, to let the hissing, whistling or percussive sound echoes.
Whispering parts alternate quickly with singing parts, the sheet music is funny and attractive, but also possesses fine details. Singers’ gestures can improve the echoes and the three-part canon.
It is as much intended for amateur adults or teenagers than to experienced singers. It can be performed in chorus or individually.
