The piece is scored for an amplified Bass singer and nine instrumentalists: two soprano saxophones and a cornet, one percussionist using a variety of instruments including sea shells and wood boxes, a Zitherist playing on a chromatic zither as well as one tuned in 13 tones, a harpist, an accordionist, a contra bassoonist and a double bass player.
…During this conversation the vulture had been calmly listening, letting its eye rove between me and the gentleman. Now I realized that it had understood everything; it took wing, leaned far back to gain impetus, and then, like a javelin thrower, thrust its beak through my mouth, deep into me. Falling back, I was relieved to feel him drowning irretrievably in my blood, which was filling every depth, flooding every shore.
Benjamin Franklin wrote about the Eagle (Aquilla):
I wish that the bald eagle had not been chosen as the representative of our country, he is a bird of bad moral character, he does not get his living honestly, when a diligent bird has at length taken a fish, and is bearing it to its nest for the support of his mate and young ones, the bald eagle pursues him and takes it from him…. Besides he is a rank coward; the little kingbird, not bigger than a sparrow attacks him boldly and drives him out of the district. He is therefore by no means a proper emblem for the brave and honest . . . of America
