What does 'ritenuto' indicate in a musical context?

'Ritenuto' is a direction in music that indicates a sudden reduction in tempo. When a musician sees 'ritenuto' in the score, it instructs them to play more slowly than the preceding tempo. This term specifically suggests an immediate change in speed, contrasting with other terms that might imply a gradual adjustment.

This distinction is important because understanding the dynamics of tempo can greatly affect the character and expression of the piece being performed. 'Ritenuto' is often used to create a sense of drama or to highlight a particular moment in the music, making it a valuable term for performers to recognize and interpret accurately.
