Euterpea is a cross-platform, domain-specific language for computer music applications embedded in the Haskell programming language. Euterpea is a wide-spectrum language, suitable for high-level music representation, algorithmic composition, music analysis, working with MIDI, low-level audio processing, sound synthesis, and virtual instrument design.
Getting Started with Euterpea
Here’s what you need to do to install Euterpea for the first time and play your first note (there is also a video tutorial):
- Install Haskell Platform for your operating system (recommended: any version from 8.4.3 through 8.6.5). You can use either the Full or Core version.
- Mac users: Haskell Platform 8.6.3 provides the simplest setup.
- Linux users: you must install ALSA (ex: sudo apt-get install libasound2-dev)
- Install Euterpea. Open a command prompt (Windows) or terminal (Mac/Linux) and run:
- Cabal 3.x users: use cabal v1-update and cabal v1-install instead.
You can check your cabal version using cabal –version from a terminal.
- Cabal 3.x users: use cabal v1-update and cabal v1-install instead.
- Install a synthesizer (Mac/Linux only): install a MIDI software synthesizer, such as SimpleSynth or Fluidsynth. Make sure it’s running before you start Euterpea in GHCi.
- Test Euterpea. Now, open a command prompt or terminal and run the following:
ghci
import Euterpea
play $ c 4 qn - Get HSoM (Optional). If you also want HSoM, which is the companion library for the Haskell School of Music textbook, you can install it with cabal install HSoM and import the library in GHCi with import HSoM.
- Mac users: to use HSoM’s musical user interfaces (MUIs), you must compile to executable rather than using the interpreter. Go to the download and installation page‘s section on “Testing HSoM’s MUIs” for information on how to do this.
Now you’re ready to head to theTutorials and Examples pages to learn about how to use Euterpea and try out some existing code. Once you’re ready to start building your own programs with Euterpea, head to the API Documentation for more information on Euterpea’s features.
Having installation trouble or don’t hear any sound? The Download and Installation page has more detailed installation walkthroughs and announcements about recent issues, and the Troubleshooting page has a list of solutions for common problems organized by category. For sound problems, you can also check out the Setting up MIDI page.
Looking for a text editor to use with Haskell & Euterpea? Here are some suggestions:
- Notepad++ (Windows only)
- Atom with a Haskell plugin (Windows/Mac/Linux)
- Or check out this extensive list of editor options.

Recent News
- (16-June-2019) Euterpea 2.0.8 on GitHub (development version) features a bug fix for some playback situations that result in dropped notes due to MIDI message ordering issues. If you are experiencing dropped notes with play or playDev, try installing 2.0.8 from GitHub.
- (13-June-2019) Euterpea 2.0.7 is on Hackage. It bumps the version of PortMidi and features some bug fixes for the cut/remove functions.
- (03-Nov-2018) Two new PDF slideshow-style tutorials are available on the Tutorials page.
- (05-Oct-2018) The Haskell School of Music textbook is now shipping on Amazon and Cambridge.
- (26-Sept-2018) Euterpea 2.0.6 is on Hackage. The only change in this version over 2.0.5 is a bug fix for infinite playback on Mac systems with multiple MIDI input/output devices.
- (03-July-2018) Euterpea 2.0.5 is on Hackage. Notable changes include dependency version bumps and a new module, Euterpea.IO.MIDI.ToMidi2, that provides a means to export more than one MIDI track with the same instrument assignment.
- (27-May-2018) Euterpea 2.0.4 is on Hackage is now compatible with Haskell Platform 8.4.2. If you had a failed installation with that version of the platform, please do a “cabal update” before trying the installation again.
- (17-Sept-2017) VividEuterpea lets you play Euterpea Music values with real-time audio processing using the Vivid library. It’s a one-file utility set that you can drop into your project folder. Vivid must be installed (easy to do with “cabal install vivid”) and SuperCollider must also be installed. SuperCollider must be running and have its server booted up before you try to play music with VividEuterpea.

Building OS X Installer Packages
After making the binary-dist, you can create a Mac installer package (.pkg) by running
The result will be a file
GHC-<version>-<arch>.pkg
, where <version>
is the full version string and <arch>
is x86_64
, i386
or ppc
. The build process uses xcodebuild
and packagemaker
.More details about building installer packages are available.
Case insensitivity
The default Mac OS X files systems (HFS+) is case-insensitive and Git is case sensitive (although this is configurable). While this ususally doesn't cause any problems, occassionally a
Unapplicable patch
error can occur. It's possible to work around this by using Disk Utility
to create a case sensitive file system and apply the patches inside of it. To do this:- Open
/Applications/Utilities/Disk Utility
. - Make sure that none of the images/disks on the left are highlighted/selected. If any are, <Cmd>+Click them to unselect them.
- Click the 'New Image' button.
- Set the 'Volume Format' to 'Mac OS X Extended (Case Sensitive)'.
- Set 'Encryption' to 'None'.
- Set 'Partitions' to 'Single Partition - Apple Partition Map'
- Set 'Image Format' to 'sparse disk image'.
- Set 'Volume Size' to 'Custom...' and select an appropriately large size. Sparse images only take up as much space is as needed, plus a little overhead, so it's better to overestimate than underestimate. A 30 GB sparse image with no data in it takes up MB.
- Set 'Volume Name' to something appropriate (e.g., 'GHC').
- Set 'Save As' to something appropriate (e.g., 'GHC Disk').
- Click the 'Create' button.

This creates a file with a
.sparseimage
extension (e.g., GHC Disk.sparseimage
) at the location that was set in step 10 and automatically mounts it. The partition can be accessed through the /Volumes
folder (e.g., /Volumes/GHC
). This partition behaves exactly like any other Apple partition except that it's case sensitive and git can apply the patches it couldn't on the case insensitive file system. After the patches have been applied, the repository can be copied to the normal file system, the partition can be unmounted, and the sparse image can be deleted.Building the documentation
For some reason, convincing dblatex to build the docs can be tricky. This worked for me:
From http://www.tug.org/mactex/ downloaded and installed
From http://dblatex.sourceforge.net/ downloaded and built
Now building users_guide.pdf will fail, as we generate things like:

(note number of backslashes). To fix this, patch param.xsl:
This is a little odd. The Debian package has this patch applied, and onDebian:
but on OS X:
so it doesn't seem like it should be needed. But anyway...
