I practice on average an hour a day by splitting up my time into several different areas: 20 minutes of technique exercises for warm ups, 10 minutes of reading music and sight reading, 15 minutes of ear training on
www.good-ear.com, and 15 minutes of learning a bass line, melody or solo to a song. Recently I've been able to fit 20 extra minutes into my routine. Should I add more time to what I'm already practice or should I look into something else to spend that extra playing time on?
