Have you seen the Haskell School of Expression book by Paul Hudak?
The book is available on line, Ch 9 and 10 talks about music.

Thanks Don,
I read the PDF. I was not able to figure out how to get the BASIC
module.
Wanted to see a reference implementation.
The DSL I want to start with is a music generation DSL ... It should
generate a wave file
with music data as input -> for example the input could contain
C3 D3 E3 ... -> should output a wave file with those notes ... some
kind of
mnemonics for tempo will also be there.
Later I'd like to incorporate parallel sequence generation -> where I
could
get chord effect etc ...
I had done a rudimentary implementation in C a while back ->

I'd appreciate it very much if you could give me some pointers on
getting
started.
Regards,
Kashyap

The Haskell equivalent would be overloading, primarily via type classes.
See Lennart Augusston's BASIC for an example of this in the extreme:
http://augustss.blogspot.com/2009/02/more-basic-not-that-anybody-should-care.html
That's BASIC syntax, in Haskell, relying on overloading numbers, strings
etc. And all statically typed.
For a survey of some of the more recent EDSLs in Haskell, see this brief
