Anton Arensky’s Quartet in A Minor for two cellos, a personal tribute to his beloved friend Tchaikovsky, is considered one of the finest Russian string quartets ever written, with the second movement being a set of variations on a Tchaikovsky theme. Meanwhile, in conversations across time, melodies ricochet from Beethoven to Arensky (as well as Mussorgsky, Rachmaninoff and Stravinsky) as Arensky paraphrases a celebratory Russian folk song associated with the coronation of the Tsar—used by Beethoven in his Quartet Op. 59 No. 2, one of the famous works commissioned by Count Razumovsky.
