Another important role for modern musicians such as professional musicians and conductors is to preserve the tradition of music theory and to convey it to future generations. It is not good enough to change the music theory established by the great geniuses of the past without permission, just because they are talented. The fact that traditional music theory is not properly inherited is a great loss for humanity.
It would be easy to understand if you imagine the world of traditional performing arts in Japan such as Noh, Kyogen, and Kabuki. Modern Noh artists and Kabuki actors first learn about the “form” that has been passed down for generations. After mastering the form perfectly, you put your own interpretation and expression on the stage. The form that has been inherited is an acting theory that has been refined through the research and practice of the generations of actors, and each movement has a profound meaning. Without studying the type of tradition at all, it would be awkward to get me to do it myself, saying, “This is a new Kabuki that I think.” It is their main business to protect and communicate the type that has been passed down from the old days, and creating a selfish style is just “play”. People involved in traditional arts must inherit such traditional culture. It’s a museum-like job, but that’s the mission.
Today’s musicians should play classical music that has made music theory exactly, in order to pass it on to future generations.
