Concerto in A Major - I. Allegro: Clarinet Book

This arrangement opens Mozart's masterwork to ensembles that might otherwise lack the resources for the standard clarinet concerto instrumentation. Dennis Nygren's scoring for solo clarinet with clarinet choir creates a warm, blended sound that emphasizes the soloist's line while providing sophisticated harmonic support, making the first movement feel both intimate and richly textured. Programming this movement alone gives you flexibility in concert planning while building toward performances of the complete concerto.

The first movement balances Classical elegance with genuine virtuosity. Mozart's melodic gift shines in the opening theme, which unfolds with natural grace; passages of rapid figuration follow, demanding crisp articulation and secure intonation. The clarinet choir provides harmonic warmth and structural clarity, allowing the soloist to inhabit a space between the intimate and the heroic.

Advanced high school clarinetists and college-level clarinet students ready for substantial solo repertoire with ensemble support. This arrangement works equally well for programs developing a mixed-ability clarinet section, since the accompanying parts can be distributed across multiple players to manage technical demands.

• Shape the primary melody with a singing tone; the opening theme needs space to breathe even when accompanied by the ensemble.
• Balance the solo line so it sits comfortably above the clarinet choir without forcing either section to compensate dynamically.
• Observe Mozart's articulation markings carefully; they define the character of individual phrases and prevent the writing from feeling uniform.
• Work the section entrances cleanly so the accompanying clarinets support rather than obscure the soloist's passage work.

Feature this as a concerto movement on a chamber or solo recital, pairing it with other Classical works for clarinet or with contemporary pieces that highlight different aspects of the instrument. The single movement structure also works as an elegant standalone performance at pops concerts or educational demonstrations of clarinet literature.

• Sustaining long melodic lines with consistent tone quality and shape
• Executing rapid scalar and arpeggiated passages with clarity and evenness
• Balancing solo articulation against ensemble accompaniment
• Responding to Classical phrase architecture and harmonic rhythm
• Ensemble coordination in mixed-ability clarinet settings
