Triple Quartet for Low Brass Choir: Brass Duo & Ensemble, Choir, Conductor Score & Parts

Hartley's conception of three distinct choirs (trombones, euphoniums, tubas) creates rich textural possibilities without requiring unusual ensemble sizes. The work showcases how homogeneous instrumentation can generate genuine musical variety and dialogue, giving each section its moment while building toward genuinely collaborative moments.

The piece has architectural clarity; you hear distinct voices building and receding, creating a sense of musical conversation. There's warmth in the lower brass sonority, with moments of brightness from the trombone section that contrast the deeper, rounder character of the euphoniums and tubas.

This work suits brass ensembles at the university level or strong high school programs with multiple skilled players in each low brass section. It is ideal for conductors seeking substantial repertoire that showcases the full range of trombone, euphonium, and tuba color without venturing into extreme technical demands.

• Balance the three choirs as independent voices first. Each section should be able to project its line without strain before bringing them together, ensuring the inner euphonium voices don't disappear under trombone brightness.
• Use the conductor score to map the sectional relationships and points where one choir answers or echoes another; these moments benefit from clear gesture and intentional space.
• Explore the lowest register of the tuba section carefully in rehearsal. Intonation stability matters here, and players should feel supported by the harmonic foundation they're establishing.

Program this alongside brass choir repertoire that calls for mixed instrumentation or full wind ensemble works. It also works as a substantial concert closer, where the homogeneous ensemble sound and clear sectional writing provide satisfying contrast to more complex orchestrations.

• Maintaining sectional balance and blend within homogeneous instrumental groups
• Reading and responding to independent voice parts in a non-traditional ensemble layout
• Executing clear articulation and phrasing across sustained harmonic passages
• Listening for and adjusting intonation in the low register
