The prolific musician Kurt Schindler (1882-1935) was a prodigy boy as pianist and composer; he explored all the field of the music, as director of opera, piano conductor, organist and recollector of field work. Although he travelled all over Europe, he had a special interest in Spain, where he made great friends as the Catalan Llu?s Millet, Francesc Pujol, the Vasc Jes?s Guridi, Norberto Almandoz or Esnaola, and the famous Felipe Pedrell, Manuel de Falla, Rodolfo Halffter and Julio G?mez. Schindler recollected hundred of Spanish popular songs and armonised them for his Schola Cantorum of New York with more than 300 voices. His interests in all Spanish Music made him to start a collection of Medieval Spanish Music in New York and Boston and start also giving concerts explaining these new repertoires.
