Re: Scheme predicative types

[Martín Rincón Botero]

Dear Aaron,

thank you very much for your help! After using ly:duration->string for the tempo-unit, I'm still missing a way to have the new string tempo-unit string in "", so that I can display it as a \note in a \markup. How can I achieve that? Sorry for taking so much of your time!

Best regards,

Martín.

I likely erred too far on the side of brevity.

On review, I probably would ignore the custom type predicate altogether,
simply using ly:music? instead.  Then within the function body add in
the logic to extract the \tempo command and provide meaningful
diagnostic messages to help users with the function should the provided
music not be appropriate.
