Squeezebox StudioA minor on a B/C button accordion
A minor uses A, B, C, D, E, F and G. On a B/C you can play the whole scale up from A3 and A4.
It has the same notes as C major, so the buttons are the same; what changes is the note the tune comes home to.
From A3 to A4
Every note of this octave is on the C row, so you can play it without leaving the row. That takes six changes of bellows going up.
Crossing the rows cuts that to four changes of bellows, at the cost of two moves between rows:
| Note | Buttons |
|---|---|
| A3 | 1′ pull |
| B3 | 3 push, 2′ pull |
| C4 | 3′ push |
| D4 | 3′ pull |
| E4 | 4 pull, 4′ push |
| F4 | 4′ pull |
| G4 | 5′ push |
| A4 | 5′ pull |
From A4 to A5
Every note of this octave is on the C row, so you can play it without leaving the row. That takes six changes of bellows going up.
Crossing the rows cuts that to four changes of bellows, at the cost of two moves between rows:
| Note | Buttons |
|---|---|
| A4 | 5′ pull |
| B4 | 6 push, 6′ pull |
| C5 | 6′ push |
| D5 | 7′ pull |
| E5 | 8 pull, 7′ push |
| F5 | 8′ pull |
| G5 | 8′ push |
| A5 | 9′ pull |
Above and below
From A5 the scale is incomplete: this box has no D6, F6, G6 or A6. 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: C major, D Dorian, G Mixolydian.
A minor on other boxes: D/G melodeon, G/C melodeon.
