The mission is to make software that aids to compose beautiful fugues and to ultimately create the fugues for the 3rd volume in the series of the well-tempered clavier: Das Wohltemperierte Klavier III.

Quotes on the Well-Tempered Clavier

The motivation of our efforts are encaptured by several quotes:

Martin Geck: "Altogether, though, The Well-Tempered Clavier is about something greater: the piece is not about the player being introduced into the realm of music, but about the music itself, which unveils a part of its universality. Martin Geck: "Doch insgesamt geht es beim Wohltemperierten Klavier um Größeres: Das Werk ist nicht vom Spieler her gedacht, der in das Reich der Musik eingeführt werden soll, sondern von der Musik her, die ein Stück ihrer Universalitšt enthüllt."
Hans von Bülow: "The Well-Tempered Clavier's preludes and fugues are the Old Testament, and Beethoven's Sonatas the New Testament for piano players." Hans von Bülow: "Die Präludien und Fugen des Wohltemperierten Klaviers sind das Alte Testament, die Sonaten von Beethoven das Neue Testament der Klavierspieler."
Ludwig van Beethoven: "Whenever I stagnated in my compositions, I pulled out the Well-Tempered Clavier, and immediately, new ideas budded for me." Ludwig van Beethoven: "Immer, wenn ich beim Komponieren ins Stocken geriet, nahm ich mir das Wohltemperierte Klavier hervor, und sogleich sprossen mir wieder neue Ideen."


The title The Pirate Fugues ought to reflect the nature of the software which is along the zeitgeist: the operators of the website ThePirateBay.org were convicted for assisting in making copyrighted content available; and Pirate (political) parties emerged across Europe. Jag lyfter på hatten för Piratbukten!

Previous work

Along the way, I discovered that in the 1980's David Cope had been successful to auto generate chorals in the style of Johann Sebastian Bach. Here is an article about his work and his views, to which I agree to a great extent.
