The goal of the app is to help finding the tone of a music piece while experimenting in jam sessions by inferring it from a given set of notes sorted by importance.

The protocol is the following:

1. The player tries several notes on top of the music
2. until they find several notes which felt and sound good -- most probably the tonic and the dominant.
3. Then, the app infers the potential tone and provides the corresponding key signatures along with the main chords.
4. The player can give a feedback by precising which notes are in or not.
5. Repeat 1-4. until a unique tone matches the set of notes.

The project is based on the following techs/dependencies:

• ReScript
• Expo
• rescript-react-native
• yarn

To run the app in local:

# Compiles ReScript files to JS -- in watching mode.
yarn res:watch

# Start Expo
yarn start

You can run the app on your smartphone by using Expo Go.

NOTE: the project has only been tested with the Expo Go app with an android phone.
