In two videos, I flesh out the need for a rolling forward wrist motion in playing the last movement of Clementi’s well-known Sonatina in C, vivace.
In addition, a 3/8 meter designation in rapid tempo requires the “feeling” of ONE impulse per measure not three. And this sense of ONENESS suggests CIRCLES of motion which are physically demonstrated in the instruction.
The supple or undulating wrist is pivotal to playing this Rondo movement with shape and contour, avoiding the pencil point, or Rosie the Riveter approach to notes. https://arioso7.wordpress.com/2011/10/20/piano-technique-avoiding-pencil-point-playing/
In this regard, I offer preliminaries to loosen up the wrist, and suggest rhythms that I enlist to develop streams of 16th notes.
There’s a slow motion frame inserted to graphically illustrate the rolling wrist motion that is so necessary to express this Classical era music with beauty and grace.
Note that behind tempo practicing, along with separate hands is always recommended.
