Our goal with this project is to create a simple, accessible tool that can be used for learning basic music theory at an approximately 5th-grade level. By way of a virtual keyboard, users can designate note combinations, and upon submission, an analysis of the chord (root and quality, or interval type if less than 3 unique notes) will be displayed. The program displays an exact match if one can be found, and the most likely result with side list of less likely results if no exact match exists. Upon recieving a chordal input, users can also seek out further information about each chord, with a piano representation, a sound byte example, and in certain situations a definition.

Compared to existing tools, we are prioritizing accessibility: users primarily recieve the simplest, most likely result, displayed as a section on the current page. Users DO NOT need an prior music theory knowledge in order to determine what the result is.

We are using materialize and an open-source Javascript keyboard to display the page, in addition to server side APIs for recieving data.

API/Reverse Chord Identifier

API/Chord Sound, Piano Display, and Progression

Materialize

Audiosynth.js and playKeyboard.js

AS A music student I WANT a tool to help me learn to analyze chords GIVEN THAT I press notes on a keyboard THEN I recieve the name of that chord GIVEN THAT I type in an interval THEN I recieve the name of that interval, including the case of unison GIVEN THAT I have recieved a chord analysis THEN I can see a visual respresentation and hear an example
