A Dictionary of Music and Musicians/Spitzflöte
Appearance
SPITZFLÖTE, SPITZFLUTE; i.e. Pointed flute. An organ stop, so called because its pipes are slightly conical, that is, taper gradually from the mouth upwards. The diameter of the top is generally one-third of that of the pipe at its mouth. The tone is thin and reedy, but pure and effective. The Spitzflöte may be of 8 ft., 4 ft., or 2 ft. pitch; in this country stops of this kind are most commonly of 4 ft. pitch.
