This cheerful piece is an excellent example of how interesting and variated music can be with just a few variations in note durations. However even though the music has a moderate skill level, we listeners can not imagine how much work there is to a piece. I have tried to compose with my notation program, and can assure you that I never can be content with what I'm ccomposing. Always something to correct and often it ends with frustration: I quit the program... So well done !
