Squeezebox StudioD Mixolydian on a B/C button accordion
D Mixolydian uses D, E, F♯, G, A, B and C. On a B/C there is one complete octave, from D4 to D5.
It has the same notes as G major, so the buttons are the same; what changes is the note the tune comes home to.
From D4 to D5
No single row has every note of this octave, so you have to cross between the rows. This is the way with the fewest changes of bellows: four going up, and two moves between rows.
| Note | Buttons |
|---|---|
| D4 | 3′ pull |
| E4 | 4 pull, 4′ push |
| F♯4 | 5 push |
| G4 | 5′ push |
| A4 | 5′ pull |
| B4 | 6 push, 6′ pull |
| C5 | 6′ push |
| D5 | 7′ pull |
Above and below
From D3 the scale is incomplete: this box has no D3. Tunes that go that far down will need a different note there, or a different key.
From D5 the scale is incomplete: this box has no D6. Tunes that go that far up will need a different note there, or a different key.
Tab is only the start
A scale shows where the notes are, but a tune rarely runs straight up the octave. Whether you play a note on the push or the pull depends on the notes either side of it, the rhythm, and whether you play along the rows or across them. Along or across the rows explains the difference.
Same notes, different home: G major, E minor, A Dorian.
