Morphology

musical + octave

This phrase is compositionally transparent: 'musical' specifies the domain (music) and 'octave' already denotes the interval of eight notes/a doubling of frequency, so a learner who knows both constituent meanings can derive the combined meaning. The construction is regular and cross-linguistically common (e.g., octave/octava), so it will be immediately comprehensible to B1 learners familiar with the parts.

Etymology

Musical octave comes from the idea that a scale moves eight notes before the sound repeats: the word octave means 'eight' and musical shows it is about sound. The higher note sounds like the lower one but vibrates twice as fast, so a musical octave means two notes that feel like the 'same' note but one is higher.
