Abjad Abjad is a Python API for Formalized Score Control. Abjad is a Python API for Formalized Score Control. Abjad is designed to help composers build up complex pieces of music notation in an iterative and incremental way. You can use Abjad to create a symbolic representation of all the notes, rests, staves, nested rhythms, beams, slurs and other notational elements in any score. Because Abjad wraps the powerful LilyPond music notation package, you can use Abjad to control extremely fine-grained typographic details of all elements of any score.
