Ball Metronome

Since people began making music together, they have used visible signals: stamping feet, moving heads, hands, or sticks. This creates a shared pulse. Mechanical metronomes use side-to-side pendulum movements, but these do not create a clear impulse. Many modern metronomes rely on flashing colors, which is not ideal when the beat is meant to be perceived only in peripheral vision. At the edge of our visual field, we perceive movement very well, but colors only poorly. The Ball Metronome therefore uses a falling motion. A ball striking the ground is immediately understandable and highly predictable. The impact creates a clear visual impulse, similar to a conducting gesture. The tempo is intentionally limited to 30–120 BPM. At very fast tempi, a falling movement becomes harder to perceive clearly. As in conducting, you can instead let the metronome indicate half notes or full measures. Examples: If you want to maintain 160 BPM in 4/4 time, set the metronome to 80 BPM. The ball impulses will then fall on beats 1 and 3. If you need 180 BPM in 3/4 time, set the metronome to 60 BPM. The ball will then indicate the beginning of each measure.
