text: The frontmost key is used, in addition to the thumb key, to create G♭ 2 and G♭ 3 ; on many bassoons this key operates a different tone hole to the thumb key and produces a slightly flatter F♯ ("duplicated F♯"); some techniques use one as standard for both octaves and the other for utility, but others use the thumb key for the lower and the fourth finger for the higher.
