I am trying to learn the Bayan (Accordion) and the book I am following has the following piece as it's trying to introduce the left hand bass system.
In the first measure I can understand the position for the first three notes (C, D and E) but I am not able to understand how the F note (played with a button right next to the C button) is expected to be played using the 2nd finger.
Is it a different button than the one next to the C button or is it basically really quick fingering change that I need to learn ?
