a web app to train musicians to identify when instruments are flat or sharp within a lifelike musical context resembling a real ensemble

What does it do?

We’re building a web app to train musicians to identify pitch discrepancies between instruments in a musical performance.  Users select a set of instruments which play an excerpt from any of several recorded pieces.  The user must identify for each instrument whether it is flat, sharp, or in tune.  Difficulty is adjusted by changing the amount by which instruments are sharp or flat.
