HarpPilot

Scales, tabs, and live pitch tracking for the 10-hole diatonic harmonica.

Pick up whichever harp is in your hand, tell HarpPilot the key you want to play in, and it works out the rest — which position to use, which notes are available, and exactly which holes to blow and draw.

What it does

Scales and arpeggios — every scale rendered as harmonica tab for your harp and position, with bends and overbends marked. Standard Richter tuning, all 12 positions.
Live pitch tracking — HarpPilot listens through the microphone and highlights the note you're playing, so you can check yourself against the scale in real time.
Tab transposition — paste a tab written for one harp and play it on another. HarpPilot rewrites the hole numbers for you, and can follow along with your playing as you go.
Find Song Key — play or hold up a song and HarpPilot estimates its key, then suggests which harp and position to reach for. Genre presets tune the suggestions for blues, rock/pop, folk/country, or jazz.
Your own library — save the tabs you've worked out, with the harp and position they belong on. Everything stays on your device.
