I watched you play that portion of the solo and I can definately see you trilling, so I tried it and worked great! I didn’t even think about it when looking at your sheet music. I’ve been working on trilling for a couple months, I found an online exercise a couple months back specifically on trilling that I actually use when warming up; it’s really helped to strengthen my “ring” finger and little “pinky” finger, especially when hitting those side keys of low C# and low Bb. Humming has really been helping me out a lot with Mack the Knife; I’ll upload it as soon as I get my webcam replaced. Humming wasn’t much of help in working on “Take Five” on the alto because it’s in 5/4 time. I will be uploading “Take Five” to the blog in time shortly.
