ImpansionExpansion

This piece can be played flexibly with tenor recorder, in higher registers with a change to alto recorder ad lib. In addition, there is a computer that generates a canon in realtime recording. The computer recording can be added flexibly in up to four channels with the canonic voices. Alternatively, a previous recorder recording can be used.

In the last part, the computer voices are each tuned 20 cents higher, so that a kind of "glissando" effect can be created for each note.
