[[Musicology]] commonly classifies pentatonic scales as either ''hemitonic'' or ''anhemitonic''. Hemitonic scales contain one or more [[semitone]]s and anhemitonic scales do not contain semitones. (For example, in Japanese music the anhemitonic [[yo scale|''yo'' scale]] is contrasted with the hemitonic [[in scale|''in'' scale]].) Hemitonic pentatonic scales are also called "ditonic scales", because the largest interval in them is the [[ditone]] (e.g., in the scale C–E–F–G–B–C, the interval found between C–E and G–B).<ref>Anon., "Ditonus", ''The New Grove Dictionary of Music and Musicians'', second edition, edited by [[Stanley Sadie]] and [[John Tyrrell (musicologist)|John Tyrrell]] (London: Macmillan Publishers, 2001); [[Bence Szabolcsi]], "Five-Tone Scales and Civilization", ''Acta Musicologica'' 15, nos. 1–4 (January–December 1943): pp.&nbsp;24–34, citation on p.&nbsp;25.</ref> (This should not be confused with the [[Ditonic scale|identical term]] also used by musicologists to describe a scale including only two notes.)
