Expand your chord vocabulary & master harmony
Explore hundreds of voicings, build smooth progressions, harmonize melodies, train your ear, and master the fretboard — thirteen interconnected modules for the complete guitarist.
Voice Leading Lab
Browse every voicing for any chord — filter by string count, inversion, and position. Build chord progressions with the smoothest voice leading and export them as images or MIDI.
Melody Harmonizer Lab
Record a melody with your mic or audio interface, or draw it in the piano roll. Harmonize it with smart chord suggestions and hear your arrangement played back instantly.
Chord Progression Generator
Generate progressions in any key, scale, and style with a tunable tension curve. Smart 'what if we replace this chord?' suggestions surface secondary dominants, tritone subs, modal interchange, and more.
Scales Lab
Every scale in every key on an interactive fretboard — formula, note names, and playback. Practice over a built-in drone (root, fifth, or any diatonic chord) and see which chords live inside each scale.
Voice Leading Workshop
A guided course in connecting chords smoothly — 6 chapters and 32 levels, from shared common tones to guide-tone lines, turnarounds, and real progressions. Hear every transition, see each chord's notes, and level up with XP.
Harmonizer Workshop
Progressive exercises in harmonizing melodies across major, minor, modal, and harmonic minor keys. 10 levels from basic triads to chromatic harmony.
Counterpoint Workshop
Write species counterpoint over cantus firmus melodies. Learn the rules of melodic independence step by step, from simple consonance to full two-voice writing.
My Chord Progressions
Your personal progression library. Save favorites from the Voice Leading Lab or the Generator, replay them anytime, rename them, and export any progression as MIDI or an image.
Ear Training Workshop
Train your ear across four modes: intervals, chord qualities, inversions, and chord progressions — graded levels from absolute beginner to advanced jazz vocabulary.
Fretboard Mastery
Master every note and interval on the neck. Per-position accuracy heat-maps show your weak spots so practice goes exactly where it counts.
Practice Routine
Chain exercises from multiple modules into a single auto-paced practice session. Build once, run daily.
Guitar Tuner
Tune your guitar with precision pitch detection. Supports standard tuning with real-time cents display.
Progress Tracking
A live skills radar shows your mastery across every module. Track XP, completed levels, and best scores — see your weakest skill at a glance.
How it works
Explore & Discover
Browse hundreds of chord voicings, discover new shapes you've never played, and hear how every inversion sounds on the fretboard.
Practice & Level Up
Train your ear, your fingers, and your fretboard knowledge through gamified workshops: voice leading, harmony, counterpoint, ear training, and note/interval ID — all scored and leveled.
Create & Export
Build smooth chord progressions, record melodies with your guitar or mic, export your work as MIDI or images, and bring it straight to your playing.
