Morphology

quarter + tone

The compound is directly compositional: 'quarter' means one fourth and 'tone' refers to a musical pitch or interval, so a learner who knows both words can infer it denotes a one‑fourth portion of a tone (i.e. a very small musical interval). Although the exact relation to a semitone is technical, the basic meaning is transparently derived from the constituents.

Etymology

Quarter tone comes from the idea of dividing a normal musical step, a tone, into four small parts. A quarter is one of those tiny parts, so the phrase means 'a very small musical interval' smaller than the usual step and used to make unusual sounds.
