I’ve found the wrist, in particular, to be pivotal in sculpting a satisfying legato AND staccato. The rolling-in motion that ignites the very first three notes has a sustaining energy that culminates in a curve around at the peak note, rolling back to the tonic. (first note) A slightly lower wrist at the start might help produce the very first roll forward into a chain link of triplets making smooth and connected playing allied to a detached approach.

In a lesson-in-progress with an adult student, “roll” and “snip” cues wedded to fluid physical motions are explored and demonstrated. (A minor arpeggio–A-C-E-A, etc.)
