Most of us saxophonists are interested in jazz or some other form of improvisatory music. In my experience, this produces a rather strong temptation to spend our practice time exploring the freer, more creative side of music. The value of exploring your creativity is going to be utterly wasted if there's no technique to support it.
Jazz is a perfect example.
One of the great ironies of jazz music is that, while it sounds so free and spontaneous, it's actually a highly structured art form. You can't really blow freely over those chord changes until you've spent many long hours systematically working out the minute details of technique, harmony, and underlying theory. Okay, hold the sarcasm. Basics Playing wind instruments is a lot like sports. It's best to schedule a regular practice time every day.
