It is always very interesting to see how little information most cellists posses about the music that we play and teach. It is even more amazing to find how little we tend to know about the development of the instrument and about the technical and musical influence that players exerted on the public, critics and composers on different times of musical history. The general trend of thought just takes the works of great composers as a fact, without relating it to the obvious parallel instrumental and technical developments. It is important to understand that all compositions have a reason for which they were created, and that a lot of these works were created for and inspired by the playing of major musical figures only remembered by current instrumental teaching for their ability to write an Etude or a technical exercise. Recent efforts in reviving old recordings from these past masters of the instrument have shown some light into stylistic playing as well as giving us a fair idea about how great these cellists were. To them we must show our historical debt for enriching the cello literature, and expanding our technical and musical understanding. Musical interaction between instrumentalists and composers keeps the evolution of music alive, expands the technical scope of the players and points the way into new development in instrumental making.
