Very interesting article. I think before I played a bit too musical, in a short time I wanted to learn many pieces without even playing them very well. Now I take more time to practice with a metronome and pay attention to the harder parts. I play them slowly working on my technique. I’m really happy the way I’m practicing now. The strange thing is that before I’ve played clarinet for years and I’ve never practiced this thoroughly as I’m practicing now with the violin. It feels like a completely new experience in music!!
