Originally composed by Wolfgang Amadeus Mozart in 1780 during his Salzburg years, the Church Sonata No. 15 in C major, K. 336 (also known as an Epistle Sonata) was initially scored for two violins, organ, and basso continuo. It is a bright, festive, single-movement work designed to bridge liturgical readings during Mass. This specific arrangement reimagines the texture as a classic string trio for Violin, Viola, and Cello, shifting the original keyboard and string dynamics into a balanced, conversational interplay among three distinct string voices.
Skill Level: Ideal for strong intermediate to late-intermediate students (approx. ASTA Grade 4–6), advanced amateurs, or professional ensembles looking for an elegant, shorter classical programming option.
Ensemble Balance & Dynamics: Moving from a keyboard-centric baseline to a traditional string trio offers an exceptional study in chamber balance. The violin holds the brilliant upper register, while the viola must seamlessly hand off inner lines and harmonic support, and the cello provides the crisp, driving foundational pulse.
Style and Phrasing: The piece serves as an excellent vehicle for teaching late 18th-century classical style. Students will focus on light, elegant classical phrasing, precise execution of appoggiaturas, and clean, tapered phrase endings.
Technical Focus: * Developing a crisp, brushed détaché and controlled spiccato bowing technique.
Mastering intonation in a bright C major key across all three instruments.
Cultivating active listening to match articulations and sustain a cohesive group rhythmic pulse.
