One of my warm up exercises Vic has given me in my lessons, is to play all the notes in the scale with a metronome, starting at the low notes and working my way up to the higher notes. They key of the day is A and here is my warm up with the metronome. I could have kept to the beat a bit better and some of the high notes could have sounded better. I liked that most of the time I kept on track and had some dynamics.
