If a piece is marked "poco à poco," how should it be interpreted?

The term "poco à poco" is Italian for "little by little" or "gradually." In the context of music, this instruction indicates that the performer should make a gradual change over time, whether that pertains to dynamics, tempo, or expression.

When this phrase appears in a score, it suggests a subtle and continuous progression, rather than an abrupt change. For instance, if it’s used in relation to volume, it might mean to increase or decrease loudness slowly, rather than immediately or dramatically.

Understanding this term is important for accurately interpreting the composer’s intentions and creating the desired effect in performance. Hence, the correct interpretation of "poco à poco" aligns decidedly with the notion of making adjustments in a gradual and measured manner.
