The notation scheme

Outline of the notation devised by Zachary Sowerby for recording ancient Greek musical notation:

• The notation is plain text, with white space delimiting syllables containing one or more notes.
• Multiple notes within a syllable are separated by a tilde ~
• Notes belong to a class that is indicated by the first four characters of the note identifier:
• gvn: Greek vocalic notation
• gin: Greek instrumental notation
• gcn: Greek common notation (the leimma)
• Following the four-character class, notes are identified by five dot-separated integers:
1. pitch (1-24)
2. accidental (1-3 to indicate first to third sharp)
3. rhythmic value (1-5 to indicate multiple of a metrically “short” syllable)
4. arsis (1 if a stigme is present, 0 if a stigme is not present)
5. hyphen (1 for presence of hyphen, 0 for absence of hyphen)
