Famously used in many horror films, this ultra famous pipe organ Toccata is one of Bach’s most popular works.
The first part of Bach’s piece is a toccata, the name of which is derived from the Italian toccare, “to touch.” It represents a musical form for keyboard instruments that is designed to reveal the virtuosity of the performer’s touch. Bach’s take on the toccata is typical in that it has a great many fast arpeggios (notes of a chord played in a series rather than simultaneously) and runs up and down the keyboard but otherwise is generally free form and gives the composer much latitude for personal expression. In Bach’s day, toccatas often served as introductions to and foils for fugues, setting the stage for the complex and intricate composition to follow.
The fugue—a technique characterized by the overlapping repetition of a principal theme in different melodic lines (counterpoint)—that is the second part of Bach’s composition reflects the particular popularity of the form during the late 1600s and early 1700s. Bach made much use of the fugue in his compositions, most famously in solo organ pieces such as this one but also in instrumental works and choral cantatas. This particular fugue, with its accompanying toccata, is not only the best known of Bach’s many fugues but the most famous of fugues by any composer.
