As there are twelve semitones within the octave, and any one of these may be taken as the basis of a key, and as every key may be formed to be either major or minor, there are consequently not less than twenty-four keys, into which, in modulating, we may occasionally move. Twelve of these transitions are adroitly performed by the agency of the diminished seventh.
