Haskell School of Music is a textbook about Euterpea and working with music in Haskell. It was originally started by Paul Hudak and was later finished by Donya Quick. The textbook contains many examples of using the Euterpea library and also graphical widgets for creating musical user interfaces (MUIs). The source code for these is contained in the HSoM library.
The textbook is currently available for order from the following websites:
- Cambridge University Press Website – available now
- Amazon.com – available now in both kindle and print format.
Regarding the PDFs in various places online: those files are NOT the same as the published textbook; they are early drafts and do not conform to the more recent Euterpea 2.x API (which is what is used in the published version of the text).
