The five bars in the Bach invention had been fighting back all week. This morning she opened PracticeBell, tapped the Invention No. 8 checkpoint, and played the passage once at ninety-two beats per minute. It came out ragged, so she graded the take Uneven, named Pulse as the cause, and wrote one line: the right hand rushed the turn. Two clean runs later the checkpoint advanced her four beats and spelled out what to rehearse next. She warmed up against the metronome, pushed the tempo ramp until her scales held, tuned one shaky arrival against the drone, then logged the session to the piece. A handful of honest records, and tomorrow knew where to begin. PracticeBell is built around that loop: name a real problem, gather honest evidence, and let the counts decide when tempo is allowed to rise. - Passage Bench turns a bar range into a checkpoint with a tempo floor, a target, an advance step, and a clean-run gate - Grade every take as Clean, Uneven, or Breakdown, tag its musical cause, and read a deterministic next-session instruction - Metronome with time signatures, subdivisions, accent patterns, tap tempo, and selectable click voices - Tempo Ramp and Gap Trainer for gradual speed work and internal-time recovery - Records live in a private local store; PracticeBell adds no advertising or analytics SDKs and asks for no sign-in, and the microphone feeds only the live tuner - Chromatic tuner and sustained drone for intonation, with scale, interval, and tempo-term references - Piece library holding composer, key, signature, BPM target, status, and per-piece history - Plan Lab, routines, tempo programs, goals, streaks, and CSV or PDF export of your own sessions
