Morphology

alto + clef

The compound transparently indicates a clef associated with the alto register because 'alto' (a lower voice/pitch range) modifies 'clef' (a pitch-sign), so a B1 learner who knows both words will infer it is the clef used for alto-range pitches. However, the exact technical specification (middle C on the third line and its routine use for viola) is specialized musical knowledge not predictable from the constituents, making it only partially transparent.

Etymology

Alto clef comes from old music practice where clefs were named for the singing part they fit. The clef shows where 'middle C' sits on the staff, and the alto position puts it on the third (middle) line, so it suits instruments with a middle range like the 'viola' and is used for viola music.
