Harp Hero – the real harmonica rhythm game!

Point your harp at your phone mic, play along to songs, get scored live on every blow, draw & bend. Perfect for learning harmonica, practicing blues riffs, or nailing classics.

⚠️ NEEDS A PHYSICAL HARMONICA TO PLAY THIS GAME ⚠️
Harp Hero is not a touch screen game. It uses your microphone to
listen to your actual harmonica. Without one, there is nothing to
play.

HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━
Notes scroll down the screen. Each note shows
you which hole to play and whether to blow, draw or bend. Hit the note
at the right time and you score — the better your timing, the
higher your points. Chain notes together to build combos and push
for a Perfect run.

After each song you get a full breakdown: score, accuracy,
perfect/good/miss counts, max combo, and a letter grade. Beat
your personal best and the game lets you know.

PRACTICE MODE
━━━━━━━━━━━━━━━━━━━━
Struggling with a song? Enable Practice Mode and slow it down —
from half speed all the way up to 2x if you want a challenge.
Speed presets let you dial in the exact tempo you need.
━━━━━━━━━━━━━━━━━━━━
WORKS WITH ANY KEY
━━━━━━━━━━━━━━━━━━━━
Got a C harp? G harp? Bb? The game supports all 12 standard
diatonic harmonica keys. Each song tells you the recommended key,
and you can override it to match whatever harp you have in hand.
━━━━━━━━━━━━━━━━━━━━
CALIBRATION & TUNING
━━━━━━━━━━━━━━━━━━━━
First-time setup walks you through microphone permission, a live
mic test (you can see detected notes in real time), and your harp
key. If your phone's audio processing adds latency, there's a
configurable audio offset so the notes line up perfectly with
your playing. A dedicated tuning tool lets you calibrate every
hole individually.
━━━━━━━━━━━━━━━━━━━━
STATS & PROFILE
━━━━━━━━━━━━━━━━━━━━
Your profile tracks everything: total play time, average
accuracy, songs mastered, best combo ever, perfect hit rate,
and your daily practice streak. Per-song high scores show your
best grade and accuracy for every track.
━━━━━━━━━━━━━━━━━━━━
SETTINGS
━━━━━━━━━━━━━━━━━━━━

WHAT HARMONICA DO I NEED?
━━━━━━━━━━━━━━━━━━━━
Any standard 10-hole diatonic harmonica. A key of C harp is the
most common and works with the recommended key for every song in
the current library.
