There's been a growing interest in the accordion. The popularity of the instrument has really gained a lot of momentum with younger audiences and we're finding more interest from people in Colorado looking for an accompanist with the ability to read and/or arrange accordion music. The music notation is similar to a piano, but there are a lot of differences too.
The right-hand manual is notated the same way as piano music, but the treble clef is used almost exclusively for piano accordions since the written range extends no lower the three ledger lines below the staff. On the other hand (no pun intended), the Stradella system is always written in the bass clef. Single notes are written in the lower half while the chordal buttons are notated in the upper half. This is in accordance with the official AAA notation notation standard adopted around the world.
