I've been practicing this from time to time as it's quite a challenge, a great SOTM choice! It's especially hard to both play in time and "play with the time", as Miles once put it. I've been asked what that means, and I take to mean changing the exact rhythmic placement of notes in the measure, often by playing the same notes behind the beat. This tune is just simple enough and complex enough to have an infinite number of variations of that.
I just calculated that it's been 494 days since I first touched a saxophone to my lips1 . Sixteen months and 9 days, or 1.33 years. Time passes, but not fast enough to get through all the exercises and long tones.
1 (Unless you count that brief encounter with the young woman in the woods of Marin County in 1973. That wouldn't be fair though, as I was unable to perform. In all fairness, I did own a bass clarinet for a short time before it was stolen. I could play a few notes in C minor concert.)
