During your first beginner piano lesson I will recommend method books and music for use during the actual piano lesson and in practice time.
PRACTICE: Piano lessons for beginners should be complemented with daily practice (even if it is only 10-15 minutes) to build confidence and dexterity. You have to practice to improve, and it's also more fun that way!
SHOULD ADULTS TAKE LESSONS ? Listening to music is a great stress reliever and playing it is even better!
