Harmonia – Guitar & Theory

● TUNER, METRONOME & DRUMS
Fast, accurate chromatic tuner. Flexible metronome with subdivisions. A built-in drum machine and jazz/rock backing tracks to practice your timing, groove and licks.

● CHORDS, SCALES & FRETBOARD
Explore chords, scales, modes and arpeggios across the whole neck. See positions, inversions and voicings. Get scale and mode suggestions for any chord or progression — perfect for improvisation.

● JAZZ, DONE RIGHT
Real jazz content most apps skip: ii-V-I progressions, turnarounds, reharmonization, tritone substitution, modes and voice-leading. Play over jazz backing tracks with the right scales suggested for each chord.

● INTERACTIVE MUSIC THEORY
A theory course you HEAR, not just read — from the harmonic series to secondary dominants and voice-leading, with listening and hands-on manipulation built in. Ear training to recognize intervals, chords and progressions by
ear.

● PEDALBOARD & LOOPER
A real low-latency guitar pedalboard: overdrive, distortion, delay, reverb, chorus, amp and cabinet simulation, plus a looper to build and practice ideas.

● SCORE EDITOR + MusicXML
Write, read and edit scores and tablature. Import and export MusicXML to work with MuseScore and Guitar Pro — your work stays open, not locked in a closed format.

● SCAN A CHORD CHART FROM A PHOTO
Turn a paper chord chart into a digital one with your camera. Processed entirely on-device — nothing is uploaded.

WHO IT’S FOR
Intermediate to advanced guitarists, self-taught players formalizing their theory, jazz students working through standards, and anyone who wants tuning, practice, sight-reading and composition consolidated into one app.

🔊 Bass and piano are cleaner, no more leaking into the effects.
