How is crescendo played?

Increase the sound progressively across the marked span, judging the rate of growth from its length, any starting and arrival dynamics, the phrase and the ensemble. The full word or cresc. can carry a dashed continuation line, especially across a long passage; an opening hairpin performs the same basic gradual-dynamic function and is often convenient over a compact span, but its shape alone does not impose one universal duration or rate. Crescendo changes dynamics, not tempo: do not accelerate unless another marking or the musical context asks for it. A structural orchestral crescendo may also add instruments, register or repeated layers while the sonority grows, but those compositional devices are not part of the word’s minimum meaning.

How does crescendo sound?

Sound that swells steadily from softer to louder, building tension or arrival.

In context

Crescendo is the Italian idea of growing. Professional notation references document the text form cresc. and distinguish it from the graphic opening hairpin. The Mannheim school led by Johann Stamitz became celebrated for extended whole-orchestra crescendi and precise dynamic control; Rossini later made a characteristic structural crescendo from repetition, progressive reinforcement and successive instrumental entries. These are historically important applications of the general instruction, not separate definitions of it.
