The Great Learning Orchestra is a network where musicians from various genres meet to explore and investigate music, in which listening is a central aspect. At the moment the orchestra has about one hundred musicians, of which a number show up for each project.

The Great Learning Orchestra, based in Stockholm, Sweden - but with members from various places, as far off as Finland and Great Britain - was initiated by Leif Jordansson and Pelle Halvarsson in 1999, and has taken on a number of compositions from the modern, experimental scene; pieces by Gavin Bryars, Dave Smith, Terry Riley, Erik Satie, Lou Reed, Pauline Oliveros, and others – always through the orchestra’s own interpretations, but if possible together with the composers, in workshops. Leif Jordansson has also started the A4 Project with The Great Learning Orchestra, encouraging one and all to contribute compositions that will fit onto a sheet of paper of the European standard size A4 (210 x 297 mm). This project has resulted in numerous new compositions, and a number of A4 concerts, called A4 Rooms, since the compositions are hung around the room, where after some of them are performed by the orchestra, which, at most occasions, is placed in the center of the room, leaving the audience explicitly free to roam the space and study the compositions during performances.

The name of the orchestra originates with the late British composer Cornelius Cardew and his work The Great Learning.
