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

Input Format

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

Example run

# 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
