sentence: Musical intervals are measured logarithmically as semitones.
sentences_after: Fractional semitones are used for non-equal temperaments. For microtuning to other tuning systems, a logarithmic scale is defined filling in the ranges between the semitones of the equal tempered scale in a compatible way. This scale corresponds to the note numbers for whole semitones.
