Op. 13 was originally written in the 1980s for 2 Trumpets and 2 Tenor Trombones. I recently revised it for a Brass Quintet - 2 Trumpets, 1 French Horn, 1 Tenor Trombone, and 1 Tuba. (The popular group 'Canadian Brass' is such a quintet.) An 'intrada' is an introduction, between acts, conclusion, or whatever - it is an old term.
Op. 61 "Fanfare for Brass" has 6 pieces for Brass Quintet. Files are 'Fanfares-1.mp3' through 'Fanfares-6.mp3' with PDF files similarly named.
Files are accessible below.
