Musica enchiriadis

Anonymous 9th-century treatise on music

Musica enchiriadis is an anonymous musical treatise of the 9th century. It is the first surviving attempt to set up a system of rules for polyphony in western art music. The treatise was once attributed to Hucbald, but this is no longer accepted.[1] Some historians once attributed it to Odo of Cluny (879-942).[2] It has also been attributed to Abbot Hoger (d. 906).[3]

This music theory treatise, along with its companion text, Scolica enchiriadis, was widely circulated in medieval manuscripts, often in association with Boethius' De institutione musica.[4] It consists of nineteen chapters; the first nine are devoted to notation, modes, and monophonic plainchant.[4]

Chapters 10-18 deal with polyphonic music. The author here shows how consonant intervals should be used to compose or improvise the type of early-medieval polyphonic music called [4] organum, an early style of note-against-note polyphony; several examples of which are included in the treatise.[4] (Scolica enchiriadis also observes that some melodies should be sung "more quickly" (celerius), others "more slowly" (morosius).) The nineteenth chapter of Musica enchiriadis relates the legend of Orpheus.[4]

The notation used in Musica enchiriadis. The scale comprises four tetrachords. The symbols indicating the notes are rotated and mirrored depending on the tetrachords. A modern transcription of the notes is below.

The scale used in the work, which is based on a system of tetrachords, appears to have been created solely for use in the work itself, rather than taken from actual musical practice.[1] The treatise also uses a very rare system of notation, known as Daseian notation. This notation has a number of figures which are rotated ninety degrees to represent different pitches.

A critical edition of the treatises was published in 1981, and an English translation by Raymond Erickson in 1995.[4]
