Collection made up of 475 compositions of which 413 are sardanas by P. Rigau. The archive also contains 10 sardanas by Joaquim Vallespí, 9 by Josep Serra and, to a lesser extent, by Vicenç Bou (4), Enric Sans (2), Ferran Says (1), and 5 pieces for voice and piano by Rogeli Rigau, brother of Pere Rigau. The presence of the "Sardana de la opera Garin instrumentada per Pere Rigau" suggests that this could be the sardana that Rigau wrote as proposed inspiration for the sardana that Tomás Bretón decided to include in his opera Garin.
