De alia musica
work by Hucbald
Quick Summary
De alia musica is a treatise by the medieval French musical theorist, scholar, and humanist Hucbald (c. 840–930). This work deals with a notational system known as daseian notation. Although it was not widely adopted, it represented an early effort to precisely indicate pitch in musical notation. The system used symbols to denote 18 specific pitches and placed the sung text on horizontal lines. Hucbald is also known for his treatise De harmonica institutione, which describes the gamut and the eight musical modes.1
