Note 7 — [E-Text Edition of Volume III - Part 1 of 2, Slice 3 of 3 - BANKS to BASSOON] (continued 10)

Op. cit. problem 29 shows the arrangement of the bellows for the wind-supply. In problem 30 is drawn a large section of the barrel, showing six bars of music represented by the pin tablature, which can be actually deciphered by the help of the keyboard included in the drawing. These diagrams are admirably clear and of real technical value. A copy of this work is in the library of the British Museum.
