A close examination of this video show a tuba tort, can you find it? This is what Tuba players mean when the whisper “lay down the B-flat.” B stands from boy.
I am afraid that even reasonably mistaken self-defense arguments will not work in this instance. One would often expect this type of conduct from a drum major, but the industry secret is that it is the Tubist that you have to watch out for. Tuba inventers Wilhelm Friedrich Wieprecht and Carl Moritz were well known in the 1830s for chasing children down the street while playing menacing E-Flat notes.
