Guitar-Logic is a tool to diagnose chords and scales on a virtual fretboard.

Currently, it only diagnoses major and minor chords. Actively working on extending support to diagnose a wider variety of chords.

Guitar-Logic can currently calculate scale notes and positions, but not display or diagnose them on the virtual fretboard.

• Write your own tabs using the virtual keyboard
• See all scales for a certain key signature
• Search for a specific scale
• Diagnose sclaes by supplying notes
• Build and save your own scales and arpeggios
• API for other sites to use

If any of those describe you, I'd love to hear from you. This is a casual, open source, exploratory project. If you feel you hav something to contribute, just open an issue.

I've written and rewritten the code in a couple of different languages, so if you're a java, ruby, or javascript person, feel free to contribute
to any of those codebases.

If you're simply interested in the project and want to use it, feel free to open an issue for a feature and I'll add it to my todo list.

Thanks for reading!
