From the developer:
Chordex brings a wealth of musical chord knowledge to your desktop.
It offers two modes of operation. In the first, you can select a chord and the app will list the notes in that chord, telling you both their names and their degree on the scale. You can also play the chord or individual notes on the built in tone generator.
You may want to check out more Mac applications, such as M-Audio Key Rig or Speak, which might be similar to Chordex.
