A great post from Liz at Helping you Harmonise:
And common sense is what stops conductors getting too self-obsessed. Yes, conducting requires depth of knowledge, and insight, and interpersonal magic and a well-honed technique, yada yada yada. But none of that has any point unless the music sounds good. It doesn’t matter who you studied with, what refinements to technique you have discovered, or what new vision of the music you have developed if you aren’t helping your performers to sound their best.
