Divertimento No. 4 in B-flat, K. 186/159b: Concert Band Conductor Score & Parts

This is genuinely early Mozart exploring uncharted territory with wind instruments, and that sense of discovery comes through in every phrase. The pairing of oboes and English horns against clarinets and bassoons creates an unusual textural palette that keeps both ensemble and audience engaged, and the writing is clean enough to reveal any balance issues in your sectionals.

Elegant and conversational, with the formality of the Classical period tempered by moments of lightness and wit. The unusual instrumentation creates a chamber-like intimacy even at full volume, like listening to sophisticated voices in thoughtful dialogue.

Intermediate to advanced concert bands looking for substantive wind music repertoire that doesn't lean heavily on the brass section. Ensembles comfortable balancing six woodwind voices and seeking material that teaches orchestration principles through direct experience.

• Balance the paired oboes and English horns carefully; they often carry thematic material over the lower woodwinds, so clarity matters more than projection.
• Work the horn parts separately from full ensemble rehearsals. These lines are rhythmically straightforward but exposed enough that any hesitation becomes obvious.
• Shape phrases across the entire wind group rather than treating each choir independently; Mozart's architecture here relies on smooth handoffs between instrumental pairs.
• Let the accompaniment figures breathe. Repeated figures in clarinets or bassoons can flatten if players lock too rigidly into a mechanical pulse.

Program this alongside other works from Mozart's wind music catalogue to trace his development, or use it as the centerpiece of a concert exploring different approaches to wind ensemble writing across composers. It works particularly well in spring concerts when audiences are ready for something refined but less heavy than autumn repertoire.

• Balancing multiple simultaneous melodic lines in mixed woodwind textures
• Performing paired instruments (oboe/English horn, clarinet/clarinet) with intonation precision
• Sustaining long-line phrasing across sectional role changes
• Reading Classical-era harmonic language and implied conducting
• Responding to transparent orchestration where individual voice quality is audible
