Sotheby's annual sale of early musical instruments, Thursday (10.30am) has the perfect gift: a mute violin. Intended for discreet practice in the early 19th century, it has no body and only a tiny sound hole. Est price: pounds 700- pounds 1,000.
The 18th- and 19th-century flutes in the sale have a lower pitch than those of today. The 'A' to which orchestras now tune vibrates at 440Hz (cycles per second) compared with 390Hz in the Renaissance. The quest for brightness of tone is to blame: military bands at the turn of the century pushed the vibes up to 455Hz. Today's 440Hz is the result of international agreement. A Richard Potter late 18th-century flute (est pounds 1,200- pounds 1,600) has three extra joints of slightly different lengths because in those days pitch could vary from town to town.
