Published by Julie Gaulke (A0.720226). This piece is designed for your more advanced students who are looking to expand their range. I've included a high E here, but in a manner that lets them gradually step up to it from the D. Later in the tune they will practice getting from high E to the C below. There is a second part that echos part I in the first half. Later in the tune the two parts play off each other.
