Harmonica Notes vs HarpBend

Harmonica Notes is a compact educational mobile app that turns your phone or tablet into a 10-hole diatonic harmonica. Its simple two-row interface is designed for beginners learning hole numbers as well as for experienced players who want a quick musical notepad on the go. It features auto-recording and annotation, and the harmonica can be tuned so you can play along with any song you hear and then copy the notes into your or your kids' musical notebook.

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 in all keys. 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. 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.
