A Dictionary of Music and Musicians/Stretto
Appearance
STRETTO (Ital.), literally 'close' or 'narrow.' A term used in two ways. Firstly in Fugue, where it designates the following of response to subject at a closer interval of time than at first. This device is usually employed towards the end of a fugue, so as to give some impression of climax. But there are plenty of exceptions to that custom; e.g.
Bach 48, No. 1.
which occurs close to the beginning. Some subjects will bear more than one stretto, in which case the closer naturally comes last; e.g.
from the 'Amen' chorus of Handel's 'Messiah.' (The inner parts are omitted for the sake of clearness.) Still more remarkable instances will be found in the fugue of Bach's Toccata in D minor.
