Morphology

major + key

The meaning is directly compositional: 'major' (the major scale / brighter, happier mode) modifies 'key' (tonality), so a B1 learner who knows both senses can infer a musical key based on the major scale. This pattern is cross-linguistically common in musical terminology and follows normal adjective+noun composition, making the phrase predictable rather than idiomatic.

Etymology

The term major key comes from the word major, which means 'bigger' or 'greater', and from the major scale that uses bigger steps between some notes to make a brighter sound. That's why music in a major key feels 'happy' or uplifting.
