Quantum Levels Revisited
A few weeks ago, I created the concept of Quantum Levels of saxophone practice. The Quantum Levels Philosophy states that we can pretend that the saxophone can only be played at discrete speeds that are multiples of 30 beats per minute. This forces the brain of the developing saxophone player to make large jumps in development. For example, instead of practicing an etude at a speed of 30 beats per minute one day, and 31 beats per minute the following day, the Quantum Levels Philosophy would state that the saxophonist should practice the etude at 30 beats per minute on day one, 60 beats per minute on day two, and 90 beats per minute on day three.
Here are the discrete Quantum Levels of saxophone practice:
| Quantum Level | Speed in Percent | Speed in Beats per Minute |
| 1 | 25% | 30 beats per minute |
| 2 | 50% | 60 beats per minute |
| 3 | 75% | 90 beats per minute |
| 4 | 100% | 120 beats per minute |
| 5 | 125% | 150 beats per minute |
| 6 | 150% | 180 beats per minute |
| 7 | 175% | 210 beats per minute |
| 8 | 200% | 240 beats per minute |
| 9 | 225% | 270 beats per minute |
| 10 | 250% | 300 beats per minute |
| 11 | 275% | 330 beats per minute |
| 12 | 300% | 360 beats per minute |
| 13 | 325% | 390 beats per minute |
| 14 | 350% | 420 beats per minute |
| 15 | 375% | 450 beats per minute |
| 16 | 400% | 480 beats per minute |
| 17 | 425% | 510 beats per minute |
| 18 | 450% | 540 beats per minute |
| 19 | 475% | 570 beats per minute |
| 20 | 500% | 600 beats per minute |
