An algorithm to generate optimal chord arrangements for chord symbols.
For more details, please refer to the paper (German, with english abstract). To use the Harmony version described in the paper, check out the corresponding commit (after cloning):
git checkout 427ec7cb95e64f2ba40c58e5e1e2a36f556cdd36Other requirements (like FGL) will be automatically installed into the sandbox through cabal.
git clone https://github.com/martinfinke/Harmony.git
cd Harmony
cabal sandbox init
