This seems to be getting a bit bad tempered.

Sometimes when that happens it's a good idea to think about the music that brought us here in the first place.

A lot of the same issues come up - the tension between the need to concentrate on the music of a particular culture, and a need to be open to learning from, and becoming familiar with other musics from other cultures. The question of how far it is right to expect people to ground themselves in the culture from which they come. The reality that for many people there is not going to be any particular culture within which they have roots. And even when there is such a culture, they may feel more affinity with some other culture. And so on and so forth.

But thank God, when it comes to the music, surely for most of us, none of this is restricted by a need to stick to what we were taught in schools, and to only have any regard for what teacher said was good for us.

And I think that most of us have learnt that in order to make the music, you've got to have a special love of one particular music, and a particular relationship to it, and that is a key to appreciating the other musics, and learning from them.
