HISTORIC FLUTES
I play a modern Muramatsu flute and a Hammig piccolo, as well as period instruments of various epochs:
A baroque flute (one key) at 415 Hz
M. Wenner, after Carlo Palanca, Turin, ca. 1750
A late baroque-classical (?) flute (one key) at 443 Hz
Anonymus
A classical flute (6 keys, C-foot) at 425-430 Hz
William Henry Potter, London, ca. 1810
Historic piccolo (5 Keys) at 430 Hz
Cabart, Paris
An early romantic flute (5 keys, D-foot) at 430-440 Hz
Clair Godfroy ainé, Paris, ca. 1835
A late romantic flute (Boehm-system, conical bore) at 438-442 Hz
Fernand Chapelain, Paris, ca. 1880
A Wooden Boehm-flute at 440-443 Hz
Richard Müller, Bremen, ca. 1935
The Querpfeife - rare old version of the piccolo flute with no keys at all which appears in the works of Telemann and Carl Philipp Emanuel Bach - I am among the few who play this instrument. I happen to own a model which plays at 415 Hz.
