This is written by me, for everyone who is tired of traditional "Hanon" scales.

Very jazzy, I almost feel like it should be a blues scale instead of a major one..

Although my very initial reaction was that I didn't really see how the cadence "goes with" the first two parts, I think it's very appealing and would add some fun/interest for those who don't like to practice the first scales and arpeggios but liked jazz. Since I am one of those people, I actually listened to the whole thing and by the time I was finished didn't care whether the cadence went with the rest! I also think the chords and melody in the cadence part are very beautiful and would make a great song or hymn.
