Between ensemble and solo performances, an insight into the practice of the string quartet. The Kuhmo Chamber Music Festival in Finland, is the perfect setting for directing a documentary on string quartets. String players from different quartets share their view on their musical practice and highlight the particularity of playing in such ensembles: how to reconcile 4 individuals with their own musical personalities. The documentary particularly follows the members of the British Lindsay Quartet during their stay in Kuhmo in 2004. They built their reputation on their recordings of the complete works for string quartets by Beethoven, Bartok and Haydn. We can attend their rehearsals and see how they negotiate their interpretation and reach a state of "synchronized individuality."
