Here we are starting to learn a new piece - Musette from Suite No. 3 by Bach. We often learn a new song by starting with pizzicato (plucking) since using the bow adds a layer of complexity. Once our left hand is solid, then we can add the bow (right hand).
I like to talk to students about the tonal patterns we find in music and also a methodical approach of how to go about practicing at home. Professional musicians don't play long sections of songs when they are working on them. Isolating the tricky spot is generally the best way to conquer it. Then it's all a matter of repetitions!
