During a rehearsal one day in 1842, Hungarian composer Franz Liszt was less than thrilled with the performance of the Weimar orchestra, which he directed. “Gentlemen, a little bluer, if you please!” he exclaimed, astounding the musicians. How on earth does one play bluer? Similar requests followed, according to a report in the musical periodical Neue Berliner Musikzeitung. Liszt demanded the orchestra not to go “so rose,” because the music was instead a “deep violet.”
