Define "dynamics" in music.

In music, "dynamics" refers to the variations in loudness between notes or phrases. This concept encompasses how soft or loud a piece of music can be, and it is crucial for conveying emotion and shaping the musical expression. Dynamics are indicated through various markings in sheet music, such as "p" for piano (soft) and "f" for forte (loud), and they guide performers on how to interpret the intensity of their playing or singing.

This understanding of dynamics is essential for musicians, as it contributes to the overall dynamics of a performance and allows for a more engaging and expressive presentation. It helps performers create contrasts within the music, emphasizing certain passages while making others more subdued, thus enriching the listening experience.

Other options address different aspects of music but do not correctly define dynamics. The speed of music pertains to tempo; arranging music for multiple parts relates to orchestration; and teaching pitch focuses on how notes are perceived in terms of frequency rather than loudness.
