My favorite part of the whole timeline (I've only read through the 16th century so far!) is what is possibly the earliest incident of trombonists causing trouble.
1467—Siena, Italy: A trombone vacancy in the palace wind band is filled by Frenchman Petro Tristano da Valenza. He begins with a monthly salary of L. 8, but receives a raise to L. 12 within months. Upon ...the first anniversary of his appointment, he is promised another raise, this one to L. 16, on the condition that he acquire and wear the required uniform worn by the other band members. He apparently refuses to do this, as he is replaced a few months later (D’Accone, Civic Muse 538).
I have to wonder what it is that he was wearing instead. Speculations?
