Here’s a great beginners piano lesson YouTube playlist from Sharon Bill filmed in 4K covering the basics of all the major scales. Sharon shows the basic construction of the major scale and then does each particular scale C major, D Major G major all the way through into the flat major scales too.
Sharon shows hands separately, hands together in similar motion and also in contrary motion over two octaves. She also gives tips on how to use the best fingering method with practical tips on posture. I also demonstrate how to give the scale more rhythmic direction and music fluidity.
