How to play Ebdim7 on the piano
| Hand | Eb | Gb | Bbb | Dbb |
|---|---|---|---|---|
| Right hand | 1 (thumb) | 2 | 3 | 5 (little) |
| Left hand | 5 (little) | 3 | 2 | 1 (thumb) |
Land all four fingers at once. If Dbb is quieter, the little finger is too flat.
The light version of Ebdim7
The fifth (Bbb) adds little colour. Eb Gb Dbb is enough to sound like Ebdim7 and is far easier to reach.
Learning Ebdim7 step by step
- Play Eb, Gb, Bbb, Dbb slowly in root position and say "Ebdim7" each time.
- Walk up through the inversions (Gb Bbb Dbb Eb, Bbb Dbb Eb Gb, Dbb Eb Gb Bbb) without lifting the whole hand.
- Play it in its ii-V-I, Ebdim7 → Em, four beats per chord.
- Finally meet it in random order between other chords, with a check on every note.
Short daily rounds fix Ebdim7 in memory faster than one long practice a week.
How Ebdim7 differs from the other 7th chords on Eb
Play the four in a row and listen to each colour.
Four ways to play Ebdim7
A seventh chord has four notes, so it has four positions. Each one is still Ebdim7.
Root position: Eb Gb Bbb Dbb
1st inversion: Gb Bbb Dbb Eb
2nd inversion: Bbb Dbb Eb Gb
3rd inversion: Dbb Eb Gb Bbb
Ebdim7 in keys and progressions
- Ebdim7 is the vii°7 chord of E minor: it pulls up one key, Ebdim7 → E / Em.
- Every note is three keys above the one before, so Ebdim7, F#dim7, Adim7 and Cdim7 use the same four keys.
- That even spacing is why Ebdim7 sounds tense, dramatic and can lead to several different chords.
- Bbb is the same key as A.
- Dbb is the same key as C.
vii°7 → i: Ebdim7 → Em
