HarpBend

The ultimate harmonica practice app.

HarpBend listens to your playing and highlights every note on the harmonica grid in real time — so you can see exactly what you're playing, nail your bends, and build your repertoire faster.

REAL-TIME DETECTION
HarpBend uses your microphone to detect the pitch of each note as you play. Blow, draw, and bend notes light up instantly on the grid — no latency, no guesswork.

VISUAL HARMONICA GRID
A clear, color-coded grid shows every hole, direction (blow/draw), and bend position. Supports both diatonic (10-hole) and chromatic (12-hole) harmonicas.

HARMONICA KEYS
C, A and G — the three harps most players own first — are included free. The Keys Pack adds the 19 others — 22 diatonic keys in all — so the grid and the detection follow whichever harp you pick up.

SCALES & MODES
Overlay any scale on the grid to see exactly which notes to target. Pentatonic, blues, dorian, mixolydian, and more — perfect for learning solos and improvisation.

CHORDS & ARPEGGIOS
Visualize chord tones directly on the grid and practice arpeggios hole by hole. From basic triads to jazz extensions.

JAZZ & BLUES STANDARDS
Practice on real chord progressions — 12-Bar Blues, Autumn Leaves, So What, Summertime, and more. The grid updates live at every chord change so you always know which notes fit.

SCROLLING MELODY
Follow the tune on a scrolling staff while the grid shows you where the notes are. "Fading Light", an original minor ii-V-i study, is included free.

METRONOME & BASS PATTERNS
Built-in metronome with adjustable tempo and accompaniment patterns (Rock, Pop, Shuffle, Walking) to practice with a full rhythmic feel.

BEAUTIFUL THEMES
Choose from Classic, Ocean, Forest, or create your own custom color theme.

Requires microphone permission for pitch detection.
