Morphology

cantus + firmus

The meaning is compositionally predictable if one recognises the Latin constituents — 'cantus' (melody) + 'firmus' (from Latin 'firmus' = firm/fixed) yields 'fixed or pre-existing melody'. However both elements are Latin technical terms (and 'firmus' lacks an English dictionary entry here), so the relation is only partially accessible to an average B1 learner without prior exposure or knowledge of Latin-derived morphology.

Etymology

Cantus firmus comes from the Latin words cantus and firmus, and literally means 'fixed song'. In early music composers kept one melody the same while other parts moved around it, so the term came to mean 'a melody used as the stable base for a piece'.
