Sonata in D minor, K. 141

Domenico Scarlatti wrote 555 keyboard sonatas, and this D minor piece — marked by Kirkpatrick as K. 141 — is among the most immediately distinctive. The technical conceit is a repeated single-note tapping in the right hand, a tremolo effect produced by rapidly alternating fingers that creates a texture unlike anything else in the keyboard repertoire of the period. Against this shimmering, almost percussive backdrop, the left hand carries the melodic and harmonic argument in longer note values. The result has an almost hypnotic, machine-like quality that anticipates certain aesthetic concerns of much later music while remaining completely idiomatic to the harpsichord. There's fire in this piece — Scarlatti spent most of his career in Spain at the court of the Queen consort Maria Barbara, and his later sonatas absorbed something of Spanish flamenco's rhythmic intensity and modal color into the Italian Baroque formal frame. K. 141 is one of the clearest examples of that fusion: technically a binary-form Baroque dance, emotionally something fiercer and more urgent. When played on harpsichord at full tempo, the repeated notes take on a kind of aggressive brilliance that piano performance can only approximate. You'd listen to it when you need music that is simultaneously rigorous and alive, precise and burning.
