Regarding the repertoire, the musicians chose two composers whose works have been on their repertoire for decades: Ludwig van Beethoven and his String Quartet in D major, Op. 18, No. 3, and Maurice Ravel and his String Quartet in F major, which the Zagreb Quartet, in one of their previous formations, recorded in 1980s for Jugoton. These two works have a number of common features, despite a distance of exactly one century – Beethoven wrote his Quartet at the very beginning of the 19th century, and Ravel at the very beginning of the 20th century. The stylistic discrepancy, between classicism and Beethoven’s early creative period, relied on the ideas of the “String Quartet’s Father”, Joseph Haydn on the one hand, and neoclassicism and Ravel's early creative period, relied on the ideas of impressionists on the other, has been overcome thanks to Ravel's view of the ideal of the classical form, that is, beauty. Obviously, also the Zagreb Quartet strives to that ideal with their interpretation based on precise intonation and a harmonious balance between instruments, enhancing it by the correct interpretation of the thematic material, with an expression that leaves a positive impression and is deprived of populist mannerisms.
