Note Duration refers to the length of time a musical note is held or sustained in a piece of music. It is typically measured in beats, with different note values representing various durations. For example, a quarter note lasts for one beat, while a whole note lasts for four beats. Understanding note duration is essential for musicians, as it helps them interpret and perform music accurately. It also plays a crucial role in rhythm, allowing composers to create patterns and dynamics within their compositions. Properly recognizing note durations contributes to a cohesive musical performance.
