[Haskell-cafe] help with musical data structures

[Stephen Tetley]

Postscript...

Hi Mike

I rather overlooked your efficiency concerns, however I wouldn't be so
concerned. By the nature of what they represent I wouldn't expect
pitch classes to grow to a size where a bit representation out weighs
the convenience of a list or Data.Set.

By the same reason - I'd only use an array for the pitch matrix if I
felt an interface favouring index-lookup was most 'comfortable'.



Best wishes

Stephen
