Harmonica Key only supports iOS 10 and earlier. For iOS 11 support check out my new app, Harmonica Key Pro.

Harmonica Key is a music reference app for harmonica players. The app provides a simple interface for looking up common harmonica tunings, as well as overlay information about chords and scales.

Players can choose to display information for different key scales and chords as well as change the root key of the harmonica. In addition, reference sounds are played when a note is touched to help players get the correct tone for bends and overblow notes.

Nice reference tool.

I think this serves a purpose for harmonica players who want to take their music to the next level, understand scales, and this may sound funny but what notes they are actually playing. I would really like to see an app (or the addition to this app) where I can simply select a key of harp and it will chart out the positions and what holes fall into each position. So if I want to play in 3rd position on an A harp, it will give me the layout. Will you consider this? Thanks....I think you are on the right track, though.

I'm giving this app 4 stars because it does exactly what it advertises, and does it well. For some stupid reason however, I assumed it would have a position chart, so I regret wasting the $1. HEY DEVELOPERS... ADD POSITIONS!

Learning to bend and over blow

If you are trying to learn how to bend and over blow on the different keys of the harmonicas this is the app .When you're learning to bend and overblow what are those notes supposed to sound like ? This app lets you hear what that note should sound like.
This is a real harmonica learning tool.
This is working on my iPad air.
Thank you
