Accordion/Right hand (Piano accordion)

The right hand of a piano accordion is played the same way as you would play a piano, with usually the same fingerings. You can use all fingers, including the thumb, to play on this keyboard.

This is how a piano accordion keyboard looks.

On most accordions, the range of the keyboard goes from the "F" below the middle "C", all the way up to the third "A" above middle "C".
