Field notes
The chord lesson connects formula, sound, and hand position: users can hear a full voicing or tap individual fretboard notes. Its explanations cover sus versus add chords, inversions based on the actual lowest pitch, and octave extensions. The page also says its voicing estimates narrow choices by fret span and fingers, while leaving the final shape selection to the player.
