///he may or may not be an idiot , but he may be a good teacher who inspires his pupils, I would not dismiss someone as a bad teacher because they said what he said, who cares a feck what its called, in equal temperament its the same thing.///

Because he's wrong, you fool. And you're wrong too. It makes a difference.

////josepp, youare talking shite, music is about enjoyment , many people can play very well but cannot read music, I can read music, I also spend a lot of time practising.
I find your atttitude intolerant////

I could care less what you think. You're wrong and you know you're wrong. And if you really knew how to read music, which i very much doubt, you wouldn't say it makes no difference.

////I think it is incredible, that you can make a value judgement on someone as a teacher , because they called b sharp c, or said b sharp doesn@t exist, or whatever , what the feck has that got to do with inspiring someone to play music.////

Okay, say your 12-year-old kid comes home from school and you notice on his homework: "Jak drove the kar to the klub at 5 o'klok." And you ask him why is spelling it that way and he says, "My teacher says there is no such thing as a hard C and that we should just use k. It sounds the same. And I really, really like this teacher." What would you do?

////if yu hadnt noticed most of the modern music is in equal temperament where in effect b sharp is c.////

Yes, B-sharp is C. That's totally different from saying there is no such thing as B-sharp. Who taught you to read music?
