hurch erpent in C by Forveille,
Paris (signed 1821), 3 keys

This instrument belonged to Alan Lumsden of the London Serpent Trio and was restored by Christopher Monk. The crook’s end of the horn was damaged, and Christopher added a metal mount that served to lengthen the instrument’s air column. While the serpent centers at A=440, its proportions and length without the metal endpiece suggest that the instrument could have either been pitched in D or C=460. Presently, we know of no other serpent d’eglise made by Forveille; this instrument is signed and dated 1821. The keywork permits the instrument to be played in either a horizontal or vertical position (British or French style). Two rear keys have been placed on the instrument, and the front key may be played by either the right index finger (British style) or the right pinky finger (French style).

Impressions of playing characteristics: This instrument’s second octave mid-range is quite flat. I must vent the 2nd octave F; however, the 2nd octave G centers beautifully with all toneholes closed and the 2nd octave A (with the first tonehole closed) proves to be the most resonate note on the instrument (and the most resonate 2nd octave A that I have ever encountered on a serpent). The first octave finger is conventional with normal pitch variations easily accessible. The 3rd octave fingering is idiosyncratic according to the player, the mouthpiece, and the bore humidity and temperature.
