C#/D layout

C#/D layout

Does anyone know of a site that gives the layout of a C#/D accordian?Thanks

Re: C#/D layout

bellows in the middle; bottons on the outside.

Or if you need more detail, try here:


you’ll need to scroll down for the c#ds

My own c#d box arrived yesterday. Hooray!

One middle-aged man has been amde very happy.

OTOH one middle aged woman, and one seven year old child have been made very miserable 🙂

good luck - chris

Re: C#/D layout

Layouts vary I’d advise doing your own diagram using a simple tuner . Gets the notes into your mind better. I use two different coloured highlighters for push and pull as well as e.g. D/E diagrams per button

Re: C#/D layout

It’s really easy to work it out based on the design, and doing so will help you to internalize it.

When you push on the bellows, you get the major arpeggio in the key of the row. On the D (inside) row, that’s DF#A. On the C# (outside) row, that’s C#FG#. On a B/C accordion these would be CEG on the C (inside) row and BD#F# on the B (outside) row. This repeats over and over, with the pitches rising as you move down the keyboard from your chin towards your legs. The low tonic note (key note of the row) will be the 3rd button down from your chin on a 21 button box and the 4th on a 23 button box. You can work out the rest of the notes by repeating the appropriate cycle (DF#A, etc.) forwards and backwards until you run out of buttons.

When you pull on the bellows, you get the other four notes in the scale (the minor 2 chord with a 6th on top). In D that would be EGBc#. In C# that would be D#F#A#c. On a B/C box, those would be DFAB and C#EG#A#. That pattern cycles, starting on the same button as in the previous paragraph.

Rarely, you might find a box where the highest or lowest button has been tuned to a more useful note, but you don’t have to worry about that unless you’re experienced.

The rule that I’ve described governing the pattern is really very simple and easy to internalize. But it necessitates a complication that makes a layout chart seem very confusing. When you superimpose a repeating cycle of length 4 on a repeating cycle of length 3, it doesn’t take long for the threes to get ahead of the fours. On the D row, this means that on the buttons 3, 4 and 5 (starting on the low D), pushing gives you the lower and pulling gives you the higher of two consecutive notes in the D scale.

But then the threes get ahead. On buttons 6, 7 and 8, pulling gives you the lower and pushing gives you the higher of two consecutive notes. This means that when going up the scale, when you go from the 5th to the 6th buttons, you have to continue to pull.

Then it gets worse. By the 9th button, the threes are so far ahead that the two notes on that button are not consecutive. The note in between them (c#) is on the 10th button (pulling). So, for the last three notes of the 2nd octave of the D scale, it’s the 9th and 10th buttons pulling and back to the 9th on the push. But very few tunes go that high, so don’t worry about it yet.

Once you find your way around the D row, learn the location of the three most important notes on the C# row: C#, F and F#.
