How is the term "allargando" defined in musical terminology?

The term "allargando" is defined as a directive to broaden the tempo, often accompanied by an increase in weight or intensity of expression in the music. This technique is typically used to create a more expansive and grandiose feel as a piece progresses, allowing the performer to emphasize particular moments within the music.

In practical application, when an allargando is executed, musicians will typically slow down slightly while simultaneously playing more expressively and heavily, thereby enhancing the musical impact. This contrasts with terms that invoke speed changes or volume decrements, as allargando seeks to impart a sense of grandeur rather than brevity or lightness. The term also does not imply a flourish or dramatic conclusion, as it is about phrasing rather than simply ending a section of music.
