Legato Bowing -Using The A Major Scale
Legato is a type of bowing that is long and smooth. In order to play with Legato bowing, we need to use the whole bow starting from the frog and going all the way to the tip of the bow. In order to play smoothly, we need to concentrate on playing with a relaxed bow arm and wrist.
All bows are the same size, but each of us have different arm lengths. The ideal bow stroke has the musician ending at the place in the bow where our arm is extended out fully with the bow straight and perpendicular to the strings. If you pull the bow too far for your arm length, then you will wind up with a crooked bow stroke.
Practice the A Major scale in a mirror to make sure you have long smooth bow strokes and that your bow stays perpendicular the entire time you are playing it.
