Allegro

Quick Definition

A fast and lively tempo.

Full Description

Allegro is one of the most recognisable tempo markings in Western classical music, indicating a fast, lively pace. The word comes from Italian, meaning cheerful or merry, and its musical use dates back to the Baroque period. In practice, allegro typically falls between 120 and 168 beats per minute on the metronome, though composers have always treated it with some flexibility depending on the character of the piece. Allegro appears across virtually every musical form — from the opening movements of Haydn and Mozart symphonies to Beethoven sonatas and Chopin études. It is often the default tempo for energetic, driving passages, but the term carries an expressive weight beyond mere speed. A passage marked allegro should feel animated and purposeful, not simply rushed. Composers frequently modify allegro with additional qualifiers: allegro moderato suggests a slightly restrained pace, allegretto is a shade slower and lighter, while allegro vivace pushes toward the very top of the range with added brightness. Allegro assai and allegro molto both indicate an especially fast reading. For pianists, allegro passages present a significant technical challenge — maintaining clarity of articulation, voicing, and dynamic shading at speed. Practising allegro sections slowly before building tempo is standard conservatoire advice. The goal is always musical intention at the given speed, not raw velocity.
