Conn 10D French horn

The Conn 10D ‘Symphony’ full-double French horn has the smallest bell throat of the manufacturer’s range of Geyer^† model (‘Symphony’ series) instruments.

Its yellow-brass bell and first branch produce a bright timbre and an immediate response, in marked contrast to the large, dark tone of the iconic Conn 8D model.

Also available in the Conn professional French horn range:

^†Most modern full-double French horns follow one of two layouts defined by the position in relation to the standard three valves of the thumb-operated fourth valve. The 'Krüspe' layout places it close to the thumb lever and first valve; the 'Geyer' layout places it after the third valve. The Geyer layout results in fewer bends in the tubing ('open' wrap) which combined with a smaller bell gives a generally brighter tone; to compensate many Geyer models are made in yellow or red brass to darken their sound. The tighter 'closed' wrap of the Krüspe layout plus a larger bell results in a characteristically dark tone, so some instruments are made from nickel-silver to add brightness.
