Clock the Beat
Backbeater is a compact tool to help drummers play at a consistent speed—or at least be more aware of variations in their tempo. The basic version clips onto a snare drum and tracks tempo in real time, then transmits the results to a smartphone for display using a free app. There’s also a Backbeater Deluxe option, which comes with a mounting bracket to position the smartphone on a nearby cymbal or drum stand for easy visibility. The app can save songs and set lists, making it a useful tool for performance as well as practice.
