In this video, I take a detailed look at the design of Avid's Sibelius - a popular music notation application. Sibelius is the embodiment of what not to do as a user experience designer and this video covers a range of examples of inappropriate design patterns and bad user interface choices. Then I go insane. This really is one of the great examples of breaking all UI design principles and every UX design principle too. It's like a design bull in a musical china shop.
