In theory no. In practice, yes.
I agree with BD about the basics - I know scales are terribly boring (exBF who is now a professional musician says they are the most boring thing in his life - poor love has to do an hour of the damn things every day) but you have to have them. And DD2 loves playing, and playing with ensembles (this is the thing I really wanted her to get out of music, to be fair, not the damn exams) and it has done so much for her...but she just doesn't do the 10 minutes that she should. I know, wearily, whereof I speak...
I have crawled out of bed but exhaustion has hit me like a truck and I think I'm going to go back. THought I had to do some work but I see that the deadlines aren't as bad as I thought and Herbs is doing the heavy lifting anyway.
Look at that rain!!!!!!
