Diminished unison

The term diminished unison or diminished prime is also found occasionally. It is found once in Rameau's writings, for example,[5] as well as subsequent French, German, and English sources.[diminished 1] Other sources reject the possibility or utility of the diminished unison on the grounds that any alteration to the unison increases its size, thus augmenting rather than diminishing it.[augmented 1] The term is sometimes justified as a negative-numbered interval,[7][8] and also in terms of violin double-stopping technique on analogy to parallel intervals found on other strings.[9] Some theoreticians make a distinction for this diminished form of the unison, stating it is only valid as a melodic interval, not a harmonic one.[melodic 1]
