Reverse Chords Finder will run a strong algorithm based on an advanced theory of chords.

Click anywhere on the guitar neck and, after 3 or more notes, it calculates the chord and its root.
So we can actually say that this is a complete chord finder. Or at least, what they call, the best reverse chord finder.

This is done based on the weight of intervals existing among the notes you select. According to this system any combination of notes, including clusters, has a root. Once the root is found, the actual chord is easily detected.

Each string's pitch can be raised or lowered within a 24 semitones range. That means you have 191,102,976 possible tunings available.
