Two of these instruments open the third movement of an F-major concerto by entering on “F G F G A G F,” then the same motif on G. This instrument only appears (-5[1])in the fourth section of the Christmas Oratorio. (15[1])Bach’s cantatas BWV 46, 67, and 162 call for the “da tirarsi” type of these instruments, likely distinguished by their tuning mechanism. This instrument plays (-5[1])a “D, high D, C-sharp, D, low D” solo accompanied by two bassoons in the “Quoniam tu solus sanctus” of the Mass in B minor. Two of these instruments play during the second of two trios bookending a polacca in the (*) fourth movement of J. S. Bach’s first Brandenburg Concerto. (10[1])Anton Joseph Hampel, a player (-5[1])of this instrument, (-5[3])invented the use of crooks (-5[1])to change its transposing (10[1])key (10[1])and the use (10[1])of hand-stopping to play (-5[1])notes chromatically. (10[3])For 10 points, name this (-5[1])coiled brass instrument (10[1])associated with hunting. (10[2])■END■ (10[8])
