What it teaches

The six chords of the stationary minor exercise, met again by leap: the same vocabulary at the greatest bass distance Stage 3 uses.

The given bass

4/4	bar 1	bar 2	bar 3	bar 4	bar 5	bar 6
Bass	D3	G2	D3	G2	A2	D3
Figures		6	6		#

The given bass and its figures (D minor, 4/4; ⌒ = tied from the previous note)

The model realization

4/4	bar 1	bar 2	bar 3	bar 4	bar 5	bar 6
Soprano	F4	E4	F4	G4	E4	F4
Alto	D4	B♭3	B♭3	D4	C♯4	D4
Tenor	A3	G3	F3	B♭3	A3	A3
Bass	D3	G2	D3	G2	A2	D3
Figures		6	6		#

The model realization (D minor, 4/4; ⌒ = tied from the previous note)

Every chord here appeared in the stationary exercise; only the bass’s journey is new. There the harmony changed while the bass held its ground — here the bass leaps a fourth and the figure decides whether the harmony leapt with it. That is Boulanger’s axis in one pair of exercises.

At the keyboard

The three upper voices of the model realization fit under one hand. Compare this under the hands with the stationary D minor exercise: the same six chords, reached by leap instead of by holding still. Carry it into A minor, G minor.
