Store description excerpt
See and learn scales, chords and shapes on an interactive guitar fretboard — in any key and any tuning. Pick a key and a scale or chord. Tonic lights up every place it lives on the neck, labelled by note name or by scale degree. Tap any note to hear it. Change the tuning and the whole map redraws to stay correct — Drop D, Open C, ten tunings in all. WHAT'S IN IT • The whole neck: 22 frets, 14 scales, 9 chord types, every key, ten tunings (free: the pentatonics in standard tuning; the rest is Tonic Pro) • The five pentatonic boxes and CAGED positions, computed for your tuning. Isolate one box, number it in playing order, or climb the neck diagonally (Tonic Pro) • Chord grips with muted-string and open-string markers (Tonic Pro) • Lessons from the open strings to CAGED and the blues. Every diagram is a playable fretboard: tap it, hear it (first lesson free, the rest is Tonic Pro) • A metronome with tap tempo, accents and subdivisions. It keeps clicking with the screen locked (Tonic Pro) THE DEAL Your first 5 days: everything unlocked, nothing to cancel. After that the board stays free: standard tuning, both pentatonic scales, every key, both labellings, and the first lesson. Tonic Pro is a one-time purchase — everything above is yours for good, updates included, on every device, with Family Sharing. No subscription. No account. No ads.
