Added the below entries to the 18th Century Timeline from Cameron’s The Crucifixion in Music (Cameron, Jasmin Melissa. The Crucifixion in Music: An Analytical Survey of Settings of the Crucifixus between 1680 and 1800. Contextual Bach studies, no. 1. Lanham, MD: Scarecrow Press, 2006). As it turns out, they are all works originating in Austria, which is not surprising, given the span of dates (1680-1800) and the fact that Austria was one of the areas of greatest trombone activity during this era in the history of the trombone.

1701—Salzburg, Austria: Heinrich Biber uses trombones to double voices in his Missa St. Henrici (Cameron 81).

c. 1720—Vienna, Austria: Antonio Caldara uses trombones to double strings in his Mass for 4 Voices (Cameron 84).

c. 1758—Austria: Leopold Hofmann alternates strings with trombones and continuo in his Missa in Honorem Sanctae Theresiae in C (Cameron 83).

1788—Vienna, Austria: Antonio Salieri uses trombones in his Mass in D to double alto and tenor vocal lines (Cameron 83).
