- NEW material 'giuliani': figures require a real voicing — the generator assigns cycle positions (bass root + upper chord tones) to DISTINCT strings with valid frets per bar; bars that cannot be voiced are skipped (deterministic), clear error when nothing fits. Patterns: p-i-m, p-i-m-a, p-a-m-i, a-i-m, p-i-m-a-m-i, p-m-a-m-i-m. Honors the chord pool, string restrictions and the tuning; one figure per beat. - 6/8 meter added (numerator 6) across score model, settings, generators; meter selects now offer 4/4, 3/4, 6/8. - Arpeggio category: Giuliani entries replaced with note-sequence broken-chord figures (1-3-2-1, 1-3-2-5(8), 1-5-3-5(8), 1-2-3-5-3) — pure pitch sequences, no voicing claims. - Beam fix (root cause): setBeam now happens BEFORE voice.draw — VexFlow decides flag vs beam at draw time; registering after drawing left both flag and beam. Beams drawn after notes, flags suppressed correctly.
Sheet Music Trainer
A web-based application designed to help musicians practice sight-reading and ear training. It listens to your instrument (or voice) via the microphone and gives real-time feedback.
Live Demo (If available)
Features
- Sight Reading Mode: Read notes from the interactive staff and play them on your instrument. The app listens and confirms when you hit the correct note.
- Ear Training Mode: Listen to a reference note and try to reproduce it. The reference note duration is configurable, and it can optionally wait for your instrument to go quiet before the next one plays.
- Phrase Mode: Practice short phrases — several bars of a single-voice line. Material: generated melodies (any key/mode, seeded), scale drills (one/two octaves or within a fretboard position, up/down/up-down), bundled exercises (verified public-domain melodies + original studies), or your own
.abcfiles. Two paces: at your pace (beginner, waits for each note) and with tempo (metronome count-in, forgiving hit/miss tracking). Note that matching checks pitch, not fingering, and repeated identical notes need a brief release between them. - Real-time Pitch Detection: Uses your device's microphone to detect notes instantly, with an analysis window and detector adapted to your instrument.
- Chromatic Tuner: Tunable needle with cents display, always-on when enabled.
- Instrument Support: Optimized for Guitar, Bass, Piano, Voice and Whistle, with configurable tunings for guitar and bass.
- Virtual Instruments: On-screen interactive guitar fretboard and piano keys for visual reference or touch input.
- Customizable: Difficulty (range, accidentals), key signatures, rhythm/metronome settings, reference note duration, microphone sensitivity, and more.
- Dark & Light Themes: Full theme support including native form controls.
- Zen Mode: Distraction-free practice interface.
