Epic music for a brass band

K: Ebmaj T: 110 BPM TS: 4/4 INST: Cornets, Flugelhorn, Tenor Horns, Baritones, Euphoniums, Trombones, Tubas (Eb/Bb basses), Percussion (Timpani, Bass Drum, Cymbals, Snare) Mood: Epic, heroic, majestic, triumphant, uplifting Structure: Intro → A (Main Theme / Fanfare) → B (Development / Countertheme) → A (Recapitulation / Climax) → C (Coda) Summary: This is a bold, cinematic brass-band piece in E♭ major at a steady, march-like 110 BPM in 4/4. Expect bright, open harmonies, strong octave and fifth doublings, and big tutti statements from cornets, trombones and tubas, supported by timpani and bass-drum hits for dramatic punctuation. Textures will alternate between fanfare-style unison/antiphonal passages (cornets/flugelhorn vs trombones/euphonium), lyrical solo or ensemble lines in the tenor/euphonium range, and full-band climaxes. Use dynamic shaping (hairpins to massive fortissimos), occasional modal/color tones or suspensions for tension, and a clear recapitulation leading into a short, emphatic coda.
