BACH, Prelude in C Minor, from The Well-Tempered Clavier, Book I; c. 1722 - 1:46
Quadruple meter, C minor, Harpsichord
Listen for the perpetual rhythmic motion of continuous running notes that are heard almost throughout. Notice the distinctive tone color of the harpsichord, in which strings are plucked by a set of plectra controlled by a keyboard.
