minor, Op. 53, No. 2, is another one-movement work. It is highly chromatic, and contains a fugue. Medtner described it as "my most contemporary composition, for it reflects the threatening atmosphere of contemporary events". Marc-André Hamelin described it as "the most concentrated 15 minutes of music one could ever hope to play or listen to". It was dedicated to the Canadian pianist and pupil of Scriabin, Alfred La Liberté, one of Medtner's most loyal supporters. The last of the sonatas, "Sonata-Idyll" in G major, Op. 56, was completed in 1937. It consists of two movements: a short Allegretto cantabile Pastorale and a sonata allegro Allegro moderato e cantabile (sempre al rigore di tempo). Piano concertos Medtner composed three piano concertos: Piano Concerto No. 1 in C minor, Op. 33 (1914–18). Dedicated to the composer's mother, this one-movement work opens with an exposition section setting out the material for the work, the opening pages of which erupt with fireworks from the piano against a surging orchestral statement of the subject. A set of variations make up the central development before the opening returns two thirds of the way through the piece. Eventually the coda sets out the romantic "big tune" before the final pages lead to an unexpectedly bittersweet ending. Piano Concerto No. 2 in C minor, Op. 50 (1920–27). Dedicated to Rachmaninoff, who dedicated his own Fourth Concerto to Medtner. In three movements: Toccata, and a Romanza from which follows a Divertimento. The first movement is propulsive with kinetic energy, and there is much dialogue between piano and orchestra (a subsidiary theme resembles the Fairy Tale from the Op. 14 (1906–07) pair, the March of the Paladin). The Romanza and Divertimento are each in their own way varied in character, the Divertimento particularly rich in inspiration. Piano Concerto No. 3 in E minor "Ballade", Op. 60, 1940–43. The factors which led to the creation of this work are closely connected to the circumstances of his final years. It is dedicated to his generous patron, the Maharajah of Mysore. Three connected movements: the first, Con moto largamente, sustained and profound, slowly developing motion and energy; the second an Interludium, Allegro, molto sostenuto, misterioso quotes the first movement and prefigures the finale; a lengthy Allegro molto. Svegliando, eroico vigorously concludes the work. Medtner recorded all three Concertos with the Philharmonia Orchestra in 1947. Chamber music Medtner's chamber music includes a violin sonata
