Church (Organ) Sonatas, Vol. II: Nos. 9-11, 13, 15 (K. 244, 245, 274, 328, 336): String Orchestra, Conductor Score & Parts

These five sonatas represent Mozart at his most economical and elegant. The string writing sits perfectly for young orchestras while the keyboard part demands enough sophistication to hold an accomplished organist's attention. Programming them as a suite gives students exposure to genuine liturgical music history without the baggage of oversized Baroque works.

Intimate and purposeful. Mozart distills the drama of the sonata into compact movements where every gesture carries weight. The organ's steady harmonic foundation anchors the strings' graceful dialogue, creating music that feels both ceremonial and conversational.

String orchestra directors seeking authentic liturgical music that challenges without overwhelming young players. These sonatas suit orchestras ready for Classical-era harmony and multi-movement thinking but not yet prepared for Romantic density. They work equally well for conductors building a chapel repertoire or programming a historically informed concert.

• Balance the organ carefully in rehearsal. The keyboard functions as both harmonic filler and melodic participant; it should be audible without overwhelming the strings, particularly in the faster movements.
• Attend to phrase shape rather than strict metronomic pulse. These sonatas benefit from natural rubato that allows the melodic line to breathe, especially in the slow movements.
• Keep articulation clean and consistent across the string section. Mozart's shorter note values demand clarity; muddiness destroys the architectural quality of his counterpoint.
• Use the continuo realization (organ score) as a guide for understanding voice leading, but allow yourself to conduct through the strings' melody and bass line first.

Present this volume as a thematic unit in a concert exploring the Classical string orchestra, or scatter the five sonatas across a season as preludes to other main-stage works. They pair naturally with other Mozart orchestral music or with a cappella choral selections from the same era. Their brevity makes them ideal for benefits, school assemblies, or services where full-length concert pieces would overcommit rehearsal time.

• Reading and performing Classical-era harmonic language (I-IV-V-I progressions with cadential clarity)
• Balancing melody against figured bass (understanding continuo's role beyond mere accompaniment)
• Stylistically appropriate articulation and phrasing in Galant style
• Conducting and performing multi-movement works with unified interpretive vision
• Coordinating with keyboard partners in chamber orchestra texture
