The enharmonic equivalent (or one of them) of the augmented Jchord is formed by adding a major third, doubly augmented fourth,and augmented sixth to a given bass tone. mm Thus the interval Ab—D$ corresponds enharmonically to the perfectfifth Ab-El? of the augmented sixth chord explained in the previouslesson. This chord is formed : First, by lowering the fifth of a diminished seventh chord (seeExample 192, a) ; Second, by lowering the fifth of a minor triad with minor seventh,and raising the root and third at the same time. (Example 192, 6.)In this form (the most useful one) it resolves to the • tonic or domi-nant chord^ according to its derivation. Thus : 92. m r :i T -fi- am 1 e: vii ?o (5b)
