Morphology

C + major

The phrase is a straightforward combination of the tonic name 'C' and the adjective 'major' meaning the major key/scale, so the meaning (the major key with C as tonic) follows directly from the constituents. This compositional pattern is common across languages (e.g. C majeur, do mayor) and adheres to standard adjective-noun naming in music, making it immediately understandable to learners who know both words.

Etymology

C major simply names a scale where C is the home note and major means a 'bright' or 'happy' type of scale. Because it uses only the white keys on a piano, people remember C major as the scale with no sharps or flats and C as its main note.
