Her interest for chamber music leads her to play regularly with Yana Tsanova, Carmen Vilà Fassier, Marina Comas or Sergio Guarné and with various chamber ensembles, such as the Neroli Trio or the Trio Clara Schumann. She also develops a pedagogical role as a piano accompanist in orchestral conducting and performance courses with maestros like Douglas Prosser, Lluís Claret or Jordi Mora. Her repertoire extends from the Baroque period to the present day. Pilar had the honour of premiering in her home country, Spain, Schulz's hourglass by the English composer Owen Leech, and Invitació al somni by the Catalan composer Feliu Gasull, with the GTR theatre company, conducted by Ignasi Tomàs.
Following a meeting with the pianist Elizabeth Sombart in 2006, she was named head of the of the Fondation Résonnance (Switzerland) in Spain.
