Hi Mikjay, I’ve transcribed the entire song and it’s available as a download…you can find it on the saxophone music section here:

For improving your speed, you can take a scale and a chord arpeggio, starting slow and building up speed. Where many can go wrong is to cheat and keep getting faster while still making mistakes along the way. A metronome can help with this by keeping you honest and I did a metronome lesson on this which you can find in the “technique” section of the lessons.

Also include chromatic scales for this!
