This was Jean Sibelius' second string quartet. It is a standout in many respects, it contains music that seems both ancient and modern by turns, some of its phrasings and techniques can stick in your mind and emotions (an "ear worm" as an associate called it) and create unforgettable moments. Here is an excellent performance of this singular 5 movement work by the Melos Quartet of Stuttgart, one of my long time favourites in this genre of ensemble for their strong clear intonation and precise yet penetrating interpretations ... and yes I tend to like German string quartets quite a lot.
String Quartet #2 “Voces intimae,” in D minor, Op. 56, (1909)
