Moveable = True for Crab Canon Example

[pikurasa]

There is a set key block = Eb major (aka C minor), however the notes are all in a minor. Without moveable=true, the music will play in a minor.

I remember Sachiko mentioning this during the workshop.

I think it is an artifact from before we had a way to specify moveable do.

Also, the Lilypond output for this example does not seem to work...

I see this error:
