Resources for sitting properly at the piano: The Well-Balanced Pianist has a great article, with before and after photos, about sitting at the piano for the most physical comfort, ease of movement, and beautiful sounding music. Nancy Faber, from Piano Adventures Method books, has a excellent video demonstration seating proper distance at the piano. This is the pedal extender I use in my studio. I am not associated with this company at all but I am enjoying their nice product. Don’t pedal like this counting horse!
