Haydn provided the inspiration for Mozart’s String Quartet in G Major, the first of six he dedicated to his mentor and friend. Tolstoy’s dark tragedy The Kreutzer Sonata was the inspiration for Janáček’s quartet, a visceral work with unforgettable power and lyricism. Grieg’s String Quartet No. 1 in G Minor is a richly sonorous work with forward-looking harmonies and rich color. There are also allusions to the folk music the composer loved, especially the earthy Intermezzo with its suggestions of the traditional Norwegian hardanger fiddle.
