Major Scales for Left Hand Accordion

Accordion Bass Scales – C Major

Accordion Bass Scales – C Major

Scales are very useful for accordion basses – they help with playing bass-lines rather than using the left hand to play the root note of the chord. Because Stradella Basses are “transposing” once you have mastered this scale you can play all the others simply by starting on the appropriate button!


Accordion Bass Major Scale Fingering

Here is the music with fingering: your left hand little finger is 5, ring 4, middle 3 and index 2. (It’s “piano fingering” so the thumb is 1 but we never use the thumb on the left hand of the accordion…..or do you?!) Notes with a line underneath like this: _ are played on the “counterbass row” (the nearest row to the bellows) all the other notes are played on the “bass row”.

Coming back down is the reverse of the above!

Dont try to do it all at once!

The first time you try to play scales on accordion basses it can be very confusing so break it down a bit – Just play C, D, E and back down E, D, C – get used to that little triangle shape. Now try the next 3 notes F, G, A – it’s exactly the same shape but played 5,3,5 instead of 4,2,4. Once you can do that you are nearly home!

Good luck and keep at it!

  1. Hi George, thank you for your help with accordion bass scales.

    I noted in an Australian AMEB accordion syllabus that the exam candidate would be asked to play scales both hands together for 2 octaves and sometimes 3 octaves. How does this work with the bass buttons?

    1. Hi Sue,
      I must do a blog about this because it comes up a lot! The short answer is play the same scale twice or three times with the left hand.
      Accordions with Stradella bass systems (2 rows of bass notes and 4 rows of chords) only have 1 octave of basses BUT each bass note plays up to 5 reeds in different octaves. Although there is technically a lowest note (not the same on all accordions) the join can be hard to hear. Imagine 5 people playing a scale up the piano all an octave apart – when the top one runs out of room they run round to the bottom and start again but the overall sound will seem to continue rising.
      Hope that makes sense!

  2. Hi George,
    First of all, thank you for your great work. Excellent job.
    Found your site searching Google as I’m learning the Bass Major Scale Fingering and noticed a small “imperfection” on this “C-major-Standard.gif”
    Going down on E, the fingering should be shown as “4” counterbass (same as when you go up) and not just “4”.
    It’s in two places: and
    If you find it that it needs to be corrected, I wouldn’t mind if you delete this comment (to avoid further confusions).
    Thanks again.

    1. John!
      Thank you – You are so right! I wonder how many noticed and never took the time to tell me? I will change them on my next editing day!
      Thanks again
