Bassoon

14 keys. 4 sections of light wood, possible boxwood. Bell: 306mm; long joint: 498mm; wing joint: 462mm; boot: 436mm;and crook. 14 brass keys with round, flat key heads, mounted in brass saddles. 2 harmonic keys linked to crook key. Overlapping touches on B, C and D keys. Brass rollers on F and A flat key touches. Tenons bound with string; This instrument has tuning devices on the tenor and long joints, consisting of a cog mechanism operated by turning a screw. Turning each of these would result in the pitch being kept steady when tuning, as opposed to when pulling out the crook only. To compensate the resulting change of position of the keys, they too have extensions, and to keep them in the correct place they each have metal “needles” which are placed into a hole. Classical styled bell, without the “modern” low Bb key attached to it. Crook key (interestingly, on the inside of the crook, directly opposite the player).
