How much practicing is required?
Because I see music study as language acquisition, I think it’s very important to:
Set up a regular time of day, with as minimal interruptions as possible
Start daily with scales to focus thinking
Practicing should start at 15 minutes per day for the youngest beginners, adding 5-10 minutes per year of continued study.
Part of the lesson time weekly will be to address issues that arise at home around practicing, i.e. motivations, balance with high school demands, problem solving.
