1812—Linz, Austria

Beethoven writes his Drei Equale for 4 trombones, a work commissioned by Kappelmeister Glöggl of the Linz cathedral. Glöggl’s son, who later becomes a music publisher in Vienna, verifies that alto, tenor and bass are the instruments commonly in use, mentioning that in his father’s “collection of old instruments he had a soprano and a quart trombone, whereas only alto, tenor and bass trombones were commonly used.” He continues, “Beethoven wanted to hear an Aequale such as was played at funerals in Linz, and one afternoon when Beethoven was expected to dine with us, my father appointed three trombone players and had them play an Aequale as desired…” (Thayer 541).*
