I used to read a charming old book called Lion by William Pène du Bois to my children. It tells about an angel who is designing a new animal, and the drawing looks wrong to him. He asks another angel to tell him one thing that's wrong with the picture. After he corrects that flaw, he asks another angel, and so on until he comes up with a picture of a lion. I love the message of that book. There were so many things wrong with the initial drawing that the designer might have decided to rip it up and start over, but once he started correcting each flaw in turn, he came up with something superb. You can't correct everything that's wrong all at once.
Musicianship is similar. So many factors are involved in playing an instrument, that you can't approach them all at once. You have to pick one problem and deal with it, hoping that one thing will lead to another. Saxophone players, to take a personal example, might address their breathing, their embouchure, and their fingering, but they have to figure out what's the most important problem or the one that's easiest to address first. YouTube is full of videos giving us useful advice.
Sometimes one imagines that the problem is with one's gear. Even if you have a decent instrument, you might not be producing the sound you want, so you experiment with mouthpieces and reeds, hoping that once you've acquired the ideal mouthpiece, you'll play like one of the musicians you admire.
Recently I tried out three of the baritone saxophone mouthpieces I've bought over the years, because the one I was using was giving me problems. Surprisingly, one of the mouthpieces that I had given up on long ago turned out to be exactly what the doctor ordered, as it were. In a recent rehearsal of the big band I play in, I was happier with the way I was playing than I have been in a while. So maybe that mouthpiece is the one thing that will change everything - but I doubt it.
In my case the one thing that would improve my playing immeasurably would be to go back in time to my high school years and practice clarinet more intensively.
Failing that, I've been listening occasionally to talks on Youtube by Molly Gebrian, a professor of viola with a strong academic background in neuroscience. A recent series of hers fascinated me: The Power of Attentional Focus. Much of the research she refers to focuses on studies of performance in sports but is clearly applicable to musical performance. The lesson I drew from her talks was that, for a wind player, to improve your sound, for example, you won't get anywhere by concentrating exclusively on your embouchure and breathing. You have to focus on your goal, the kind of sound you want to produce. As you approach that goal, your muscles will find the way of doing it. Thinking about your lips and opening your throat can get in the way of using your lips right and opening your throat!
Gebrian says that you have to focus on something outside yourself. I'm trying that, and it works. Her videos assume an audience of music educators and young musicians aspiring to become professionals. Although I don't fit into that category, I find them insightful and useful.
