Oboe. Nominal pitch: C.

Technical description: Built in two sections only with division below R3 hole, however the sections do not separate and the instrument is effectively in one piece. African blackwood with german silver keys, reed well, bell rim and ferrule at the socket. The bore is narrow down to the bell where it flares only slightly. The wood in the bell is exceptionally thick. Simple octave keys. The keywork of this instrument adopts many features of the Boehm flute which adapted to the clarinet but failed to become established on the oboe. Most notable among these are the larger finger holes and the inversion of the right hand brille mechanism enabling F♯ to be fingered with R2 and F♮ with R1 (as on modern flutes and clarinets). On this instrument F♯ can be fingered with R2 or R3, or using the R3key. The three rings on the right hand are connected, as are the left-hand rings and there is a connection between the two sets of rings so that lowering any of the right hand rings lowers those on the left hand. B♭ and C can be obtained with the R1 side keys as on a normal simple system instrument, but the linkages make it possible to play B♭ with L1 plus L3 or any right hand finger or the R3key. The Ckey for L0 operates as a thumbplate; the thumb normally rests on the key and it must be lifted to obtain the C. The vent for the C♯ stands open; the lowCkey also depresses the C♯. There is linkage between the lowB and the lowCkeys. There is no articulation between R1 and the G♯key. L0: C; 8.1. L1: P; 8.2. L2: R; C♯tr. L3: R; . L4: G♯; lowB; E♭-dup. R0: sup. R1: R; B♭; C-dup.
