Thank you very much Cary!

Thank you very very very much for your advices !Your work is incredible.And sorry for my english,I’m french.
Okay but is it bad to practice too much? Something like 6 or 8 hours a day.I think it’s impossible to be efficient during 8 hours of work.

I play piano and sing in a band,this is my job.How many times a day should I practice?How many times a day the professionals practice?Thank you
