Keyboard Layout

The main objective of modernizing treble keyboard of the piano accordion was to make the layout of keys more compact.

1.1 To this effect, N.A.Kravtsov eliminated the spaces between the black keys and placed them in one row, adjacent to one another, without gaps between them. This made an octave 30% shorter in length.

 

1.2 Eliminated narrow parts of white keys will be placed in a separate row next to the relevant black keys and their wider parts (white keys) will stay unchanged in their positions.

 

1.3 In order to solve the placement of the white keys between the black keys Bb and C#, we split wider parts in halves and then place white keys B and C in there. The same thing is done with the keys E and F, which are placed analogically.

 

1.4 Then we shift the lower part of the white keys for half a step.

 

1.5 Free gaps in the row (where ex-narrow parts of the notes D,G, and A are placed) are filled with doubled keys of C and F.
