I had an interesting experience today and thought I'd share it with others. For the last few days, I have been learning a new song, but there was a bridge section that was giving me some trouble. I decided to turn on the metronome and work on that section exclusively. After I was able to play the section flawlessly on the metronome, I decided to play along to the whole song. However, as I approached the bridge section I started fearing its difficulty and once I got there, I couldn't play it cleanly to save my life. I tried it a second time and it was even worse. I thought of a quote I had read in The Inner Game of Music, which went something along the lines of, "Something is either easy or it is impossible." The theory behind this is that if you truly believe that playing a certain piece of music is easy, then you'll likely sail right through it. However, if you view it as hard or difficult, you will create some doubt that you will not perform it well, and you'll be thinking more about failing than succeeding. I took a few breaths and remembered how easily I played the part against the metronome. I built back up my confidence and tried it again. As the bridge section came up I told myself, "This is easy. I got this". The part came and went and I played it flawlessly. I then played the song a few more times just to make sure it stuck, and had no issues. It's funny what a little confidence will do.
