An Open-Source application for the study of music theory and keyboard skills that takes input from a MIDI keyboard and outputs staff notation. Various analytical vocabularies of melody and harmony are represented. As a practice aid and exercise platform that operates across aural, visual, and tactile domains, this tool accelerates the acquisition of fluency in certain fundamentals of tonal music.

• Requires Python 3.6.x and Pip to install.
• To install Pip, see their instructions.

$ git clone https://github.com/ospreyelm/HarmonyLab.git harmony
$ cd harmony
$ pipenv install
$ ./manage.py migrate
$ ./manage.py runserver

You should now be able to run the application on your localhost at http://127.0.0.1:8000.

Chrome is currently the only browser supported, being the single browser that implements the WebMIDI specification.

This application can be deployed to any platform that supports python and django. One such example is heroku, a cloud platform as a service provider, which makes it easy to deploy changes directly from the git repository.

Create a Heroku app with the Python buildpack and the Herok Postgres add-on. Deploy from the desired branch of this Github repository; automatic deploys are good for testing the basic playing interface, but these should be disabled when creating course and exercise data.

The required Config Variables that should be added on the app settings page are as follows:

SECRET_KEY = YOUR_RANDOM_LONG_PASSWORD
DJANGO_SETTINGS_MODULE = harmony.settings.heroku
ALLOWED_HOSTS = ["yoururl.com"]
LTI_OAUTH_CREDENTIALS = {"your_lti_key":"your_lti_secret"}

To create an admin account for creating course and exercise data, use the Heroku CLI as follows:

$ heroku login # one-time setup
$ heroku apps # view app names for your login
$ heroku run python manage.py migrate --app HEROKU_APP_NAME
$ heroku run python manage.py createsuperuser --app HEROKU_APP_NAME
