cantus firmus(noun) a melody used as the basis for a polyphonic composition. Cantus firmus. In music, a cantus firmus is a pre-existing melody forming the basis of a polyphonic composition. The plural of this Latin term is cantus firmi, although the corrupt form canti firmi can also be found. The Italian is often used instead: canto fermo.
The line of counterpoint must be compatible with the cantus firmus, but it must also maintain its independence from it. This species is written in whole notes, like the cantus firmus. The line of counterpoint begins on a P5, P8, or P12 if it is above the cantus firmus (example 2a), and on a P1 or P8 if it is below the cantus firmus (example 2b).
