Description

AI generated. Clef Hearth is a focused standalone browser practice tool for reading the bass staff.

Generate four bar phrases in C, G, D, F or B flat major. Choose quarter notes, mixed eighth and half note rhythms, or quarter rests. The original notation renderer includes key signatures, stems, flags and ledger lines.

Demonstrate plays the phrase. Practice supplies a count in and metronome while you answer with mouse or computer keys. Note accuracy and input timing are scored once per due note, with misses and extra inputs recorded. Export an exercise MIDI file or a practice report.

Setup requirements

Open index.html or serve the folder with any static HTTP server. Use a deliberate play action to enable audio.

Dependencies and ongoing costs

No third party libraries, paid APIs or required services. A current Web Audio capable browser is required. Optional static hosting can be free.

Known limitations

AI generated browser practice aid. Not a formal music examination or learning certification. Bass clef, four bars and 4/4 meter only. Input timing includes browser and hardware latency; manual correction is not automatic calibration. The latest 200 assessed events are retained in memory. Note hints are allowed without changing scores. Exported MIDI uses short articulation gaps. Hosted downloads may be restricted.
