Ilyana has been studying piano for two years. Currently, she's working on various weight applications for staccato.
I found that imaging a basketball being bounced vs. a ping pong ball being tapped, helped the student with her overall physical approach.
The short video below illustrates. We ended up playing 8th notes, not being overly ambitious to tackle 16th notes as originally intended.

In this second video, I was exploring varying depths of staccato when I played through Scarlatti Sonata in G, K. 14
