Drop2: Jazz Guitar Ear Trainer

Drop2: Jazz Guitar Ear Trainer - your complete practice coach

Drop2 listens to your playing through the microphone and gives you instant, note-by-note feedback - no cables, no interface, just your guitar and your phone. It even hears you over its own backing band: play along over the speaker, no headphones required. A smart scheduler points your practice at what you haven't nailed yet, and a weekly report says what to work on next. No guitar to hand? Tap the neck instead, or train your ear alone.

Works with acoustic and electric guitar. All listening happens on-device - your playing never leaves your phone. For iPhone and iPad. In English, French and Japanese, with note names in English, German or solfege.

FRETBOARD TRAINER
Hear a note, then find and play it anywhere on the neck. Start with naturals, add sharps and flats, then the whole fretboard. Spaced repetition drills the positions you keep missing.

PRACTICE WITHOUT A GUITAR
Guitar in the other room? Tap the answers instead. The app names a note and a string and you find it on the neck; it names a chord and the voice on top and you build the grip with four taps. Moves drills voice leading: the grip you are leaving is on the neck, the next chord is named, and you build the voicing that moves the voices least - then comp a whole tune the same way. Same scheduler, no microphone.

SCALES & ARPEGGIOS
Play the one-octave scale or arpeggio for any root and chord quality and have each note checked by ear. A full-neck map colors the chord tones so you see the shape as you learn it. A curriculum opens new keys and qualities as you master the basics.

LINES - SOLO OVER THE CHANGES
Walking bass and drums loop a progression or standard form - ii-V, the blues, So What, Blue Bossa, Autumn Leaves, All the Things You Are, and more - while you improvise. Targets mode prescribes the guide tone to land each bar and grades your voice-leading. Free mode classifies every note live - chord tone, tension, avoid or outside - on a color-coded neck map. Score on headphones or over the speaker: an on-device model picks your guitar out of the band.

DROP-2 VOICINGS
Learn and drill the essential jazz voicings across roots, qualities, inversions, and string sets. Browse any shape, hear it strummed - then the app names a chord, you play it, and all four notes are scored, octave by octave, so it tells inversions apart. Includes ii-V progressions, a daily review, and a play-along band to comp the changes with.

EAR TRAINER
Drop2 plays an interval, a chord, a cadence or a phrase, and you answer on the neck: intervals as degree-labeled circles, chords as real drop-2 voicings in any inversion - name the quality, or the voice on top - cadences as voice-led shapes, and jazz phrases you tap back note by note. Hold any answer to hear it first. Then pick up the guitar: hear the line over its chords and play it back, and the app checks every note.

PRACTICE THAT ADDS UP
Every drill has a finish line: a run of questions, a strip that fills, and a result card with your score and personal best. Tell the app how long you have and whether you have a guitar, and it plans the day's workout - an ordered route across the trainers that hands you on as each step is done. Each week it reads your log back to you: what you mastered, what is solid, and the one thing to work on next. Behind it: streaks, a heatmap, accuracy trends, coverage grids, iCloud sync, a widget and a daily reminder.
