Chorale Builder

Haskell + Lilypond chorale interpreter. Converts chord progression into 4-part Bach-style chorale sheet music + midi audio.

Dependencies

For Ubuntu/Debian users:

sudo apt-get install haskell
sudo apt-get install lilypond

The program reads in an input of a chord progression. The progression should be saved to progression.txt

Format Rules

Write chords in roman numeral format.
Use uppercase for major, lowercase for minor. (Only major and minor chords supported at this time.)
Use b or # for flat or sharp chord root.
Separate chords with spaces.

Example

I V vi iii IV I IV V

# cd git root
echo "I V vi iii IV I IV V" >> progression.txt
chmod +x chorale.sh
./chorale.sh
cd output
ls       # you should see the outputted files
