If there is hint of blue note— it is contrived. If there is semiprecious structure it is all by rote. Because there is mastery — there is no mystery.
Adroit hands show only gloss and felicities death. Surprise is supposed in the onslaught of notes. How sad are the fingers that smooth them over.
The scales are mere trapeze and not a razors edge. Your instrument is placation as your feel is dead. Hurrah when you finish— no one hand is clapping, The hill is climbed, but the great mountain is laughing.
