If you want to improve at your instrument, enjoy your lessons, and get the most out of your musical education, a daily practice commitment is necessary. How much you practice each day depends on your age, level, instrument, and musical goals, but here are some very general guidelines:
Beginner 15-30 minutes/day Preliminary-Grade 2
Lower Intermediate 30-45 minutes/day Grade 3-5
Upper Intermediate 45-60 minutes/day Grade 6-9
Advanced 1-2 hours/day Grade 10 and above
