I think the "classical music" today has reached only a small percentage of the global's population. The fact that many musicologists, theorists, and performers have written substantial analysis that are so academically orientated that are tough to graps. (Maybe I am wrong). Many people are neglected to listen to classical music.
In today's society, the classical music does not reflect on today's soceity, envirnoment, the pace of lives etc. I think the classical music can be enjoyed by more people, when the communication is clear.
The communication between the performer and the audience should have a common ground. Whether, the music is from the past or present, it must be able to reach out to the public. This is where there will be a discreptencies on interpretations, such as tempi, articulations (instruments have evolved, and advanced itself), dynamics, techniques, nuances etc. throughout each centuries.
