Tin whistle all the holes closed, the whistle generates its lowest note, the tonic of a major scale. Successively opening holes from the bottom upward produces the rest of the notes of the scale in sequence: with the lowest hole open it generates the second, with the lowest two holes open, it produces the third and so on. With all six holes open, it produces the seventh. As with a number of woodwind instruments, the tin whistle's second and higher registers are achieved by increasing the air velocity into the ducted flue windway. On a transverse flute this is generally done by
Tin whistle or C instead of C on a D whistle). This makes available another major scale (F on a C whistle, G on a D whistle). The standard range of the whistle is two octaves. For a D whistle, this includes notes from D to D; that is, from the second D above middle C to the fourth D above middle C. It is possible to make sounds above this range, by blowing with sufficient force, but, in most musical contexts, the result will be loud and out of tune due to a cylindrical bore. Traditional whistle playing uses a number
