My college professor once told me, “You can’t get rid of bad habits; you can only replace them with new ones.”
I went to school for a B.S. degree in Music Education, with my major instrument being French horn. To make a long story short, though I had been learning the instrument since I was 10 years old, I was never satisfied with my level of playing. Even after four years of being in the U.S. Army Bands, I wanted to get better. My hope was that individual instruction by a good horn professor could fix my problems.
The big thing I had going for me was that I am a musically gifted person. I have a good ear for pitch and intonation, a strong sense of rhythm, and a knack for being able to sight-read music (i.e., play sheet music without having seen or practiced it before). But being able to play an instrument requires more than a musical mind, one must also have the correct technique physically to be in control of the instrument and make it do what you need it to do.
And this was where I had my problems. My breathing, embouchure (“the use of facial muscles and the shaping of the lips to the mouthpiece of an instrument”), tonguing, and posture were not fundamentally sound; thus, I could not always produce the music the way my mind wanted to. I had formed some bad habits that needed serious changing.
