Whole or Half

 B or C

With the Roland accordion, you get both B and C systems. Make a menu selection.

I started with a B-System accordion, but with Roland I still have a B-System but also a C-System.

So, can I get used to a C-System?

Whole or Half Steps

Switching systems means the half-step and whole-step diagonals switch places.

So, the key difference is identifying half-steps and whole-steps in the music. 

After playing scales, chords, and grace notes, it is time to start playing some songs.

Play Songs

Getting used to a new keyboard system means getting used to playing songs. The key element is identifying the melodic intervals. 

Between the B and C keyboard layouts, the long row is the same (minor third, diminished fifth, major sixth, and octave). So accurately identify and play the half-steps and the whole-steps.

Particularly good songs to practice are those with half- and whole-steps.

"Dark Eyes"

Starts off with half steps.

Then a fourth, a half step, minor third, then a mix of half-steps, whole-steps, thirds, fourths, and fifths.

Here is a French jazz version, ala Django Reinhardt.

Shostakovich Waltz No. 2

Tritenina plays the waltz.

Can you identify the half steps versus the whole steps?
