Tempo in beatboxing refers to the speed or pace at which a beatboxer performs their vocal percussion rhythms. It is typically measured in beats per minute (BPM) and plays a crucial role in establishing the overall feel and groove of a beatbox performance. A faster tempo creates a sense of urgency and energy, while a slower tempo can evoke a more laid-back or relaxed vibe. Beatboxers often use tempo variations to add dynamics and variety to their routines, contributing to the overall musicality of their performance.
