It's been decades since my beloved N.Y.C. piano teacher, Lillian Freundlich bestowed upon me the gift of Domenico Scarlatti Sonatas. And at the time, (while I was a student at the New York City H.S. of Performing Arts) I had no idea that those she had selected were permeated with the basics of technique bonded to musical expression.
Yet, I have no specific recollection of my mentor having isolated finger staccato from that generated by the forearm. Similarly, wrist staccato was even more foreign to her musical vocabulary. (Nonetheless Mrs. Freundlich always checked for supple wrists, and for relaxingly suspended arms without a trace of tension)
Basically, Lillian Freundlich's springboard was the singing tone, and how to phrase by building smaller measures to larger ones using a free fall relaxed arm and a progressive note-grouping approach. She also doted on the dotted 8th/16th rhythm to smooth out bumpy lines.
As years have passed, and more than one teacher has influenced me during an extended musical journey in and out of the Conservatory, I've come to the conclusion that identifying and isolating various types of staccato is part of the enriched piano learning cosmos–that such a physical/musical nexus is intrinsic to growing artistry.
Excuse my wordy introduction, but perhaps it's a necessary prelude to a tutorial I prepared right after having resurrected Scarlatti Sonata in G, K. 14, L. 387 as part of my spiritual homecoming.
Having observed reams of detached notes in forte and piano dynamic ranges permeating the score, I realized how fortunate I was to have spent inordinate time with my adult students cultivating various kinds of staccato via scales and arpeggios around the Circle of Fifths. It clearly amounted to a common journey of infinite value!
Finally, to have reviewed a Baroque era composition that was exemplary of the Keyboard School of Virtuosity fathered by Domenico Scarlatti, afforded an opportunity to re-explore staccato playing in all its expressive facets.
