GoKawiilGitori data: G string's 8th fret is guitar's toughest note to identify
Gitori analyzed 275,169 answers collected over three years from more than 10,000 players of its Find the Notes fretboard game. The data shows the upper-middle of the neck, especially the G string between frets 6 and 9, is where players most often misidentify notes, with the G string's 8th fret (E♭) wrong about a third of the time. By contrast, open strings and the 12th fret, along with the low and high E strings generally, are answered correctly far more often, with error rates around 6%.
