Almost all modern music conforms to the ubiquitous twelve-tone equal-tempered scale. This scale offers simplicity and consistency, but it lacks the precisely tuned harmony that just intonation can provide. Using this interface, you can find justly-tuned chords similar to any single-octave equal-temperament chord. Click on a chord to hear it. Then shift-click to hear the equal-tempered chord and decide which one you like best.
