Tap tempo is a feature commonly found in music equipment, such as metronomes and digital audio workstations. It allows musicians to set the tempo of a piece of music by tapping a button in time with the desired beat. The device then calculates the tempo based on the speed of the taps, providing a precise beats-per-minute (BPM) value. This function is particularly useful for live performances and practice sessions, as it enables musicians to quickly adjust the tempo to match their playing style or the energy of a song. By using tap tempo, artists can maintain better rhythm and synchronization during their performances.
