Ein schöner Tag (English: A beautiful day) is the first single from Schiller's 2001 album Weltreise with vocals by German singer Isgaard and spoken word passages by German actress and voice actress Franziska Pigulla (* 6 May 1965), who became famous in the German-speaking countries as a narrator of countless documentaries and as the voice of FBI Special Agent Dana Scully from The X-Files.
The styles of the song and of the music video of Ein schöner Tag are very close to the previous single Ruhe.
The vocals by Isgaard are a sample of the theme "Un bel dì vedremo" from the opera "Madame Butterfly" by Giacomo Puccini.
The song will be included on Opus - White Album and had its premiere in the Schiller Lounge on German Klassik Radio.
The official music video for "Ein schöner Tag" was produced by Blau Medien GmbH and was shot in 2000 by German director Marcus Sternberg.
