In the 18th and 19th centuries, classical improvisation was a vital part of the performance and compositional process. Performers and composers--often one and the same--improvised as freely as jazz musicians do nowadays. Currently, very few classical musicians are able to improvise in a classical manner.
Many classical pianists are uncertain how to begin improvising in a contemporary classical style. Although many effortlessly perform the works of Ravel, Scriabin, and Messiaen, when presented with the opportunity to learn improvisation they are often taken down difficult paths, either being taught to "play by ear", or taught to improvise on a very basic level.
My templates for classical improvisation play to the strengths of classical musicians. Based on sight reading and the advanced yet tonally logical musical languages of Ravel, Scriabin and Messiaen, these templates encourage a kind of mix and match approach which opens up a vast world of improvisational resources.
