Harmonica
- Beginner — even with only a C harmonica, a registered song can be played in C.
- Intermediate — transpose to the key you want and play the harmonica you own.
Why Chord Guide
This is not an app that plays MP3s.
It is an app that turns an MP3 into a song you can actually play.
Chord Guide — hear it, see it, play it right away.
The difference
Why it is different
Your own digital score
Unlike a player where listening is all you get, Chord Guide analyzes the song and shows lyrics, chords, and harmonica guidance on one screen, following the playback position. "Listening along" becomes "playing along."
Lyrics in a normal app are just text. Here lyrics, guitar chords, and harmonica holes all move on the same timeline.
From "too hard" to "I can play this"
The original key is often too hard. Transpose, easier chords, capo, and key match lower the difficulty. Even with only a C harmonica, most songs can be prepared to match your instrument.
Pick the key and capo position that your hands can reach today.
Vocal only, MR only — change how you practice
Sing along with the vocal, practice karaoke style with MR only, or keep just the singer's melody and play the rest yourself. Playback stays in sync; only the practice mode changes.
Loop, speed, and section practice work the same way in every mode.
Sing with two lyric lines
You can sing a song with two kinds of lyrics. Even across countries, people can sing K-POP using a second lyric line written in their own language.

Chord Guide is not a tool for listening to a song. It is a tool that lets you play it. Start with the song already on your drive and turn it into something you can perform.
