In the case
Everything Chopinly carries, each on its own page. All of it is free, runs in the browser, installs to a phone like an app and works offline. The practice clock and logbook are the spine; the rest are the tools you reach for while the clock runs.
- MetronomeA pendulum on the Web Audio clock; accents, subdivisions, tap tempo; survives a locked screen.
- PianoA keyboard sized to the screen: chords, glides, sustain, one to four octaves.
- TunerA chromatic tuner on the mic: cents dial, note name, hertz, A4 calibration.
- Pitch pipeA sustained reference tone on any note in any octave; A4 calibration.
- RecorderRecord takes from the clock; they stay on your device, attached to the goal; compare A and B.
- ScoresPDF scores with tap-to-turn pages, bookmarks and Pencil ink on a separate layer; big scans cached.
- Sight singingA melody on the staff, a count-in, then every note you sing is judged on pitch and rhythm.
- ComposeTap-to-write notation on a grand staff: playback, PDF into your scores, MusicXML both ways.
- Ear trainingHear a note or a chord, play it back — on the screen or on your real piano through the mic.
- Practice logPress play, name the goal; minutes, notes, history and analytics follow — no forms.
