Grand Chorus and Dialogue: Concert Band Conductor Score & Parts

Marlatt's arrangement transforms an organ masterwork into a showstopper for concert band by weaponizing the antiphonal brass setup. The dialogue between the back-of-hall brass quartet and the main ensemble creates spatial drama that no traditional arrangement can match, and the orchestration captures all the harmonic richness of the original while letting the band shine on those big, resonant chords.

Stately and dignified, with moments of architectural power. The original organ grandeur translates into waves of harmonic color, and the antiphonal structure creates a call from the heavens answered by earthbound voices. There's a liturgical weight to the music balanced against accessible melodic warmth.

Directors programming a Grade 4 band with solid ensemble control and the logistics to position musicians in antiphonal formation. This works equally well for a concert band with strong brass players seeking a piece that showcases both the section and the full ensemble's capability.

• Position the antiphonal brass (2 trumpets and 3 trombones) at the rear of the hall or stage, separated by clear distance from the main band. This spatial separation is essential to the piece's dramatic effect and must be established in rehearsal.
• Balance the full band so the back brass doesn't disappear during unison passages. The goal is dialogue, not echo; both groups must project with confidence.
• Shape the brass entrances with intention. These aren't punctuations but call-and-response statements. Conductor and back brass leader should establish eye contact or use a wireless monitor if the distance is significant.
• Pay attention to the harmonic language. The Romantic vocabulary and organ-derived voicings demand rich, singing tone quality from all sections, not a bright or thin articulation.

Open a concert with this to command attention and demonstrate your band's sophistication in spatial and harmonic control. Its dramatic architecture also works beautifully mid-program to provide a textural and emotional shift from lighter fare, giving the audience a moment of contemplation before moving into the program's final section.

• Responding to antiphonal/spatial musical cues across rehearsal room or performance space
• Balancing harmonic texture in Romantic-era scoring
• Maintaining ensemble integrity during call-and-response passages
• Singing with warmth and resonance in sustained harmonic progressions
• Coordinating brass intonation across separated sections
