Two "Thumb Over" octaves ascending and descending, then two "Thumb Under" octaves ascending and descending. The video shows the RH playing two octaves TO, ascending and descending, played twice. This is then repeated using TU. To non-pianists, these may appear to be essentially the same, although the TU motion was slightly exaggerated. This illustrates why videos of piano motions are not as helpful as one might think. The TO motions ascending are basically correct. The TO motions descending has one error -- a slight bending of the nail phalange of the thumb. At these moderate speeds, this slight bending does not affect the play, but in strict TO, the thumb should remain straight for both ascending and descending play. This example illustrates the importance of learning TO as soon as possible. My tendency to bend the nail phalange is the result of using only TU for many decades, before I learned TO. Watch the lessons on scale playing on Youtube by others and you will see that most of them teach only TU. However, when they play scales fast, they use motions close to TO. To see those videos in slow motion, go to YoutubeSlow. Motions not demonstrated in my videos are glissando motion and the pivoting action on the passed finger for TO legato.
