It was much freer and I experienced a wider vocal range. In addition to the musical changes, I noticed a greater focus on goals in my life. I felt more centered. I was also hearing music in my head more clearly. This made me more aware of the importance of the music you hear inside you.
Most people concentrate on just the playing and work to fix the technical problems.
But you hear the music inside first and this is what fuels your desire to recreate the sound. I believe that music schools and teachers assume that somehow inner listening just develops. They don't really ever explain to their students that the whole thing starts inside your head with something that you hear. Generally teachers believe that if you develop a certain technique you will play better. But a better technique will only reproduce more accurately the sound that you want, the sound that you hear inside and imagine.
