UPDATED: Katharina Wagner says that Tom Tykwer will NOT direct the Ring at Bayreuth in 2013.
Tykwer is also a composer of film music. His soundtrack career grew out of financial necessity. According to his Homepage he had no budget for a composer, so turned his own hand to the task. These first composing experiences led him to the "great discovery that the composition process actually begins with the scriptwriting, and that with the search for the language of the film, it finds its tone melody and harmony." Meanwhile, Tom Tykwer has put his music to all his films.
Originally motivated by putting together a soundtrack, the music now composed by Pale 3 (Tykwer/Klimek/Heil) is not only film music. And in co-operation with Xaver Naudascher, the creative process of scoring music outside the realm of cinema is sometimes a kind of liberation. "It is like with writing or painting: with a semi-elaborate computer, music you think up can be transformed immediately. The music exists, regardless as to whether or not you have any financial backing."
Tom Tykwer's motto on his Homepage is:
"I like everything that speaks to me loudly, and that gives me a vision. I don't care about the genre. It's the same for all arts, and the same for film and for music."
