Recently the students of the UWSP cello department gave their opinions after reading an interview with Janos Staker. I chose to write about this because I know that vibrato is a big issue to all cellists. Starker says that a wider vibrato because it sounds out of tune, and the adjacent notes can be heard at times. I agree that being able to hear adjacent notes is not really a desireable thing, but I don't think that it always has to be thin and narrow. I think that it depends on the mood of the piece, and should be chosen based on the emotions that are felt by the player.
Nothing is written in stone when it comes to music.
I like that. I think it is hard to limit emotions sometimes. There is such a fine line between letting your emotions be seen in your music and being obnoxious. The discussion of the different types of love are interesting too. Starker says he cries in his own way.
