I just purchased a digital piano, and playing some synthesia to get a feel for it. I am using default settings where notes for right hand is shown in green, and notes for left hand shown in blue. Game suggest that I should switch my thumbs for C4 as shown below.
I am feeling more comfortable keeping my right hand thumb on C4, but I don't want to acquire bad habits. For cases like this, is it recommended to keep my finger fixed, or should I switch?
