Grand Sonata in A major, Op. 22

Composed around 1821 and published in London, the Grand Sonata Op. 22 is the most ambitious and formally rigorous of Sor's works for guitar, designed to demonstrate that the instrument could sustain the weight and intellectual seriousness of a full Classical sonata. Its three movements — a weighty Allegro moderato, a lyrical Andante, and a virtuosic finale — place extraordinary demands on the player's command of counterpoint, cantabile tone production, and right-hand independence. The work played a central role in Brian Jeffery's landmark scholarly reassessment of Sor's output and remains a cornerstone of the advanced guitar repertoire.
