For an amateur theatre, we need a track that is played live and loops in the background while all crew are presented. The track should end soon after the presentation, and it is not known how long the presentation takes. How can such a track be created without being too boring.
- A long track may contain more variation, but needs more time if it needs to end at a complete cycle
- A short track can stop anywhere, but may be too repetitive.
Would a short chord progression with changing melodies do the trick?
From the comments, I realize that I did not emphased that the music is going to be played live, by living musicians. So there is no stop button.
