I would like to recommend that you try Euterpea, which you can find on my course website:
http://plucky.cs.yale.edu/cs431/ If you click on the “Software Resources” tab, you will find detailed installation instructions for multiple platforms. Euterpea also comes with a textbook, which you can find on the “Reading” tab.

I am using GHCi (6.12.3) on Windows XP. May I request you to assist me for the following please. I am trying to install packages related to Music. What are the packages I can install and how? Please provide me detailed information (packages, documentation, literature or tutorial). I have tried like this: A. Check for cabal update: I have tried with at ghc command prompt: ghc>cabal update -v But the the message remains the same as before: Downloading the latest package list from hackage.haskell.org<http://hackage.haskell.org/> cabal: failed I couldn’t figure out the problem here. B: Tried to install a package (mtl-1.1.1.0 as an example) manually. 1. I have installed ghc in F:\ghc drive. 2. As a trial, I have downloaded the package mtl from http://hackage.haskell.org/package/mtl-1.1.1.0 3. I have used cygwin to unpack the files. 4. At DOS prompt (F:\Haskell\Literature\Packages\mtl-1.1.1.0\cabal install) - It looks like installing in C:\Documents and Settings\userID\Application Data\cabal\mtl-1.1.1.0 At Prelude I have issued a command (Prelude> :show packages), it does not show the package mtl. But it shows these packages: packages currently loaded: base ffi-1.0 ghc-prim integer-gmp rts I think the package mtl-1.1.1.0 should be in F:\ghc\lib\mtl-1.1.1.0 After installation of a package, how one can test that using an example. Once again, thank you very much for the time you have given. Regards, Deb
