Euterpea is a multi-platform, domain-specific language, embedded in the functional language Haskell, for computer music development. Euterpea is a wide-spectrum language, suitable for high-level music representation, algorithmic composition, and analysis; mid-level concepts such as MIDI; and low-level audio processing, sound synthesis, and instrument design.
- (31-May-2016) HSoM 1.0.0 is now on Hackage.
- (31-May-2016) Euterpea 2.0.3 is now on Hackage. Please note that HSoM requires 2.0.3 now and will not work with earlier versions of Euterpea.
HSoM currently requires the GitHub version of Euterpea (2.0.3). This is a temporary issue and is part of preparation for new Hackage releases.
- (18-May-2016) With the Creators Update, Euterpea will now work on Windows 10 with any version of GHC 8.0.2. The “play” function finally works on 64-bit versions without issues! However, there is currently another bug that means you can no longer double-click hs/lhs files to open them with GHCi. There are two options:
- Choose to open hs/lhs files with WinGHCi (right click, select “open with”, then search for WinGHCi)
- Open a command prompt or PowerShell in the folder you want*, start GHCi from there, and then load the file. You can open PowerShell by going to the folder, then selecting File > Open Windows PowerShell.
- (17-Apr-2016) Musical User Interfaces (MUIs) should work on all recent Macs now! See the special Mac instructions for HSoM on the download and setup instructions page (it involves reinstalling GLUT in a very particular way).
- (22-Dec-2016) New additions: one-page quick reference PDFs for Euterpea’s note-level and signal-level features. These are meant for quickly looking up what some of the most commonly used features are without digging through Euterpea’s source code or the HSoM textbook.
- (22-July-2016) The Examples page has been updated.
- (9-May-2016) Euterpea-2.0.0 is now available on Hackage!
What’s on this site
- Library setup information:
- Haskell School of Music – a textbook detailing Euterpea and its applications. The textbook comes with its own library, HSoM, that expands on Euterpea and includes Musical User Interfaces (MUIs).
- API Documentation – features available in the Euterpea and HSoM libraries.
- Yale Haskell Group Website – historical information on the research group at Yale that originally created Euterpea. Please note that the group is no longer active, its members having long since dispersed to other places and universities.
