Toccata
A keyboard showpiece of touch and velocity, tightening as it runs
Related
A toccata is a keyboard showpiece, its name from the Italian toccare, to touch. It is built from fast scales, arpeggios, repeated notes and chords in free textures, often opening with an improvisatory rush before turning to strict counterpoint.
In the Baroque era the toccata often served as a prelude to a fugue, as in Bach's organ works; in the twentieth century Ravel, Prokofiev and Khachaturian made it an experiment in piano rhythm and touch.
The ear goes not to a tune but to the hands: how one figure is shifted, accelerated and thickened across the keyboard. The difference from an etude is purpose — an etude trains one technique, a toccata displays the whole keyboard's explosive power.
