Thanks Jasen,
This piece is meant for classically trained accordion students in the intermediate level. I've been playing the accordion during my whole life, but unfortunately enough, we didn't have the opportunity to study it in conservatory (didn't even exist). All there was, was private tuition: expensive and so depending of the quality of the teacher and his vision. You could call this concerto some sort of compensation for what I was never able to do. My musical studies went in another direction.
Since the concerto is written for bayan or convertible, the yodelling project won't do any good. The accordion required for this project should have two discant keyboards (left and right) to play full counterpoint between hands. A traditional accordion has a right hand discant and a left hand bass/chord unity. A modern convertible accordion can play both techniques. Therefore it is called 'convertible' and can compete with most classical orchestral and soloing instruments as to play range, phrasing and dynamic movement on a very high virtuoso level.
Thanks for listening. The rest is soon to come.
