[Haskell-cafe] DSL in Haskell

[CK Kashyap]

Thank you very very much Daryoush ... I had not seen the book ... Looks pretty interesting, I saw it mentioning Midi though ...
Thank you Justin for the location of the BASIC module.
Regards,
Kashyap

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.
