🟢show_metronome(bpm, beats_per_bar, beat_unit, subdivision, accent_pattern, ...)

Use this when the user wants a metronome, online metronome, 120 bpm metronome, tap tempo or a metronome for practice. Opens a live beat widget with 20 to 400 quarter-note BPM, 1 to 16 beats per bar, accents, subdivisions and an optional ramp with up to 1000 tempo stages. Reports milliseconds per beat and subdivision. The widget runs only while on screen; audio timing depends on the device. Does not record audio or detect pitch.

🟢calculate_tempo_values(bpm, milliseconds, note_value, modifier, beats_per_bar, ...)

Use this when the user wants bpm to ms, a delay time calculator, tempo calculator, note cycle hertz, milliseconds to beats per minute, bar length or song length. Accepts BPM or a note duration and returns whole to sixty-fourth values, dotted and triplet, pre-delay suggestions and approximate Italian marking ranges. BPM is quarter notes per minute, 20 to 400; up to 100000 song bars. Hertz is rhythmic repetition, not pitch. Does not record audio or detect pitch.

🟢plan_tempo_practice(start_bpm, target_bpm, step, step_type, minutes_per_step)

Use this when the user wants a metronome for practice with a tempo ladder from start to target BPM, a BPM or percent step and minutes per stage. Returns the ladder table, total time and CSV download. Supports ascending or descending 20 to 400 BPM with up to 200 stages; percent steps round to 0.001 BPM and target gets the full stage time. Does not track sessions or record audio.
