Organum and discant

Rhythmic ligatures are used in the transcription of organum, discant and copula. The underlying rhythm must be transcribed to cause the ligatures to line up correctly. A short measure length (in this example 3/4, breves are transcribed as quarter notes) compresses the music together and allows for line breaks between divisiones.
