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
Finger agnosia magnetic stimulation (rTMS), they noted both finger agnosia and acalculia in the test subjects when areas of the intraparietal sulcus were stimulated. They concluded that the areas underlying finger agnosia and acalculia are extremely close to one another, but distinct. These areas receive blood from the same branch of the middle cerebral artery. Any damage to that blood supply would cause symptoms of both acalculia and finger agnosia. As in many other agnosias, those with the disorder have difficulty recognizing their errors and often do not correct themselves. There is no known treatment for finger agnosia. Typically, finger agnosia does
