Way 2 of 5
1st Inversion (RH)
intermediate
First inversion — the 3rd (C#) moves to the bottom. Reach for it when the chord before this one sat a step below: your hand barely travels.

Way 3 of 5
2nd Inversion (RH)
intermediate
Second inversion — the 5th (E) is in the bass. It leans forward instead of settling, which makes it a good passing chord.
Keys: E4 · G4 · A4 · C#5
Way 4 of 5
3rd Inversion (RH)
intermediate
Third inversion — the 7th sits in the bass. Unstable on purpose; it wants to fall into whatever comes next.

Jazz Voicing (LH)
