(1) Diminished intervals are those made le than minor, e.g.: & sharp to F sharp is a diminished 7th, because G to F being a minor 7th, & sharp to F contains one semitone le than the minor interval. Some authors, however, apply this term in a manner liable to lead to much confusion, namely, to a perfect interval when made smaller by one semi tone, and to an imperfect interval when made le by two semitones; thus, according to them. c to G flat is a diminished 5th, but C to E double flat , or c sharp to E flat , a diminished 3d. [INTERVAL.] (2) Diminished subjects or counter-subjects are subjects or counter-subjects introduced with notes half the value of those in which they were first enunciated.
