One clean tick a second, nothing spoken and nothing to read — this is the simplest steady beat there is. Count reps or breaths out loud against it, pace a reaction drill, or keep a one-per-second cadence honest without staring at a clock. Press start and it keeps ticking; it comes set for half a minute, but the run is yours to extend.
At sixty ticks a minute it doubles as the slow end of a musician’s metronome — an even, unaccented pulse rather than a downbeat, which is why it suits counting and pacing far better than keeping a musical bar.
