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.
