Re: Changing notehead sizes within chords

[David B. Stocker]

Klaus and Thomas,

Thank you. These are exactly the kind of thing I was looking for.

I've been starting to fool around with scheme and it's going very 
slowly. Maybe examining these and learning how/why they work will help 
me with the lilypond-specific scheme knowledge required to start solving 
some of these challenges.

Do either of you recommend a source on Scheme for beginners?

Thanks,

David
