stretto [It., narrow, close]

(1) [Ger. Engführung] In a *fugue, the imitative treatment of the subject at a shorter interval of time than is employed in the initial exposition. The technique is often reserved for a climactic moment near the end. It is also employed in the *ricercar, beginning in the 16th century. (2) In nonimitative works, a climactic, concluding section in a faster tempo; often stretta. Examples occur in the finales of Italian opera (e.g., Rossini’s Il *barbiere di Siviglia, act 1). The term is also often applied to passages such as the conclusion of the fourth movement of Beethoven’s Fifth Symphony.

Italian Concerto

A “Concerto in the Italian Manner” for solo harpsichord with two keyboards by Bach, BWV 971, published in 1735 as the second part of the *Clavier-Übung. The work is so named because it is in the form and style of the Italian instrumental concerto of the early 18th century, the concerto’s characteristic element of contrast being achieved through contrasting *registrations on the harpsichord’s two keyboards.

double time

In jazz, the use of rhythmic values twice as fast as the prevailing values without, however, changing the tempo of the chord progressions, which in such a case is typically slow. Often introduced in the course of an improvised solo.

In a *concerto, it marks the point at which the soloist is to play a *cadenza.
