Jonathan Bellman writes that modern concert performance style—set in the "conservatory" tradition of late 19th- and 20th-century music schools, and suitable for large auditoria or recordings—militates against what is known of Chopin's more intimate performance technique. The composer himself said to a pupil that "concerts are never real music, you have to give up the idea of hearing in them all the most beautiful things of art." Contemporary accounts indicate that in performance, Chopin avoided rigid procedures sometimes incorrectly attributed to him, such as "always crescendo to a high note", but that he was concerned with expressive phrasing, rhythmic consistency and sensitive colouring. Berlioz wrote in 1853 that Chopin "has created a kind of chromatic embroidery ... whose effect is so strange and piquant as to be impossible to describe ... virtually nobody but Chopin himself can play this music and give it this unusual turn". Hiller wrote that "What in the hands of others was elegant embellishment, in his hands became a colourful wreath of flowers."
