So, now I'm gonna play the D major scale, two to a bow.
The D major scale, as you can see, that was a three octave D major scale. That goes up pretty high on the E string. So it's one of the more difficult ones. And if you get really good at the violin, it's very useful for all the great concertos: Beethoven, Brahms, Tchaikovsky. So, practice your D major scale.
