Sort of. I'm probably quite biased because I was never told what the hell is the point, and I found no use for it whatsoever yet I was graded and had to jump through the hoops anyway. I hate that sort of thing, I want to know WHY I'm doing things, not just do them out of obligation. Funny that this is the only part of all my studies that I feel that way, but maybe if had a better teacher, yet everyone just turns up the same excuses that don't sell me the thing at all.
I don't think you can HURT someone's musicianship by getting them to do whatever ear training exercises. I think it's just a matter that I for one would like tangible proof that doing 3 voice dictation is worth my time and I haven't seen any, and all I hear is that it might help but it's always so vague and so far in my experience it hasn't. It's just made me angry.
I'm not -against- any sort of ear training, my problem is with a curriculum that requires you to pick out which note is missing from a 12 note cluster. Seriously. Or being able to transcribe four part chorals by ear? Who the in the name of Jesus H. Christ needs a skill like this? I certainly don't! It's like if I was required to, I don't know, become really skilled at snowboarding. What the gently caress is the point, again? Unless you like snowboard, yeah, but I don't see the connection and it's a really hard thing to train!
