String Quartets (Ligeti)
The Hungarian composer György Ligeti published three string quartets: two string quartets proper (1953–54, 1968) and a student piece from 1950 published toward the end of his life. The first two quartets represent his early period, inspired by Béla Bartók, and middle period, which was largely micropolyphonic.
In 2012, sketches and notes for his projected String Quartets Nos. 3 and 4 were discovered by Bianca Ţiplea Temeș at the Paul Sacher Stiftung, and represent Ligeti's late period.
