Why “Drop2”

The name is a voicing.

Take a four-note chord in close position and let the second voice from the top fall an octave: the harmony opens up and settles under the hand. That’s a drop-2 voicing — the grammar of jazz guitar comping, from Wes Montgomery on down.

This app began life as a drop-2 trainer. The name stayed; the ambition grew.

What it does

It hears you

Play into the mic and Drop2 recognizes pitch and chord voicings in real time — no cables, no MIDI. Your guitar is the controller.

The fretboard, note by note

Hear or see a note, then find it on the neck. Spaced repetition keeps resurfacing the ones you miss, until you know every note on every string.

Scales and arpeggios, by ear

Play the one-octave shape for any root and quality, in any position. Every note is checked by ear, and the chord tones light up on a full-neck diagram.

Drop-2 voicings

Every inversion across three string sets — learn them with playback, drill them by playing, then comp them in time over the band. maj7 · 7 · m7 · m7♭5 · dim7 · mMaj7

Solo over the changes

A walking bass and drums loop the tune you pick, in any key. The app names the guide tone to land on in each bar — or grades every note you choose to play instead.

The unglamorous part

A chromatic tuner, a metronome with a drum-kit voice, streaks, an activity heatmap, and a daily plan that targets exactly what you’re due to review.

“The point isn’t to finish a course. It’s to hear a phrase and know where it lives on the neck.”
