Allargando

Allargando, abbreviated allarg., calls for a broadening of the music: slower in tempo and usually fuller in tone. The literal Italian meaning is ‘widening’ or ‘making broader’, and the result should feel exactly that — the phrase opens out, the texture deepens, and the listener senses arrival.

The distinction from rallentando is mostly emotional. Rallentando merely slows down. Allargando does so while gaining weight and grandeur, usually with an implied crescendo. Composers use it at structural arrivals: the return of a principal theme, the recapitulation of a sonata, the final cadence of a symphony.

Elgar, Sibelius, and Strauss use allargando frequently in their broad late-Romantic perorations. Film composers borrow the gesture for end-credit cadences. Performed correctly, allargando feels inevitable — like a great ship coming to dock.

Italian gerund of allargare (‘to broaden, widen’), from al- + largo (‘broad, wide’). Common in scores from the late 19th century.

Don’t confuse allargando with ritardando. The tempo broadens, but volume should swell, not fade. In ensembles, lengthen the bow, support the breath, deepen the bow contact — match the breadth of the slowing with breadth of sound.
