Here the key of D sharp minor, the dominant of G sharp minor, is not reached till the third bar of the answer.

68. Our next example illustrates a point of considerable importance—

J. S. Bach. Wohltemperirtes Clavier, Fugue 46.

Here the last note of the subject is D flat, the minor third of the tonic; but the last note of the answer is not A flat, the minor third of the dominant, but A natural, the major third.

69. That this is by no means an isolated case will be seen by the following examples, taken from a much larger number that might be given—

Mozart. Requiem.
