Main Release

This version was pushed to maplelab.net on July 5, 2016.

The purpose of this application is to visualize a large dataset in an easy-to-understand way.

It organizes a lot of data from Bach's Well-Tempered Clavier into a contained tool. The Piano Menu at the top left is the main controller; Form switches between Preludes and Fugues, Key switches between Major and Minor, and the Keyboard chooses Chroma (ie B, F#, A). After making three selections, the applet should populate with all the relevant information. This includes tempo data across performers and editors (tempo plot on the bottom right), and a snippet image of the relevant score.

This project was based on a larger research project in the MAPLE Lab exploring music and emotion.

Features:

• Interactive piano menu
  • Allows you to quickly select one of the 48 pieces in Bach's Well-Tempered Clavier
