Before lessons with Jeff, my practice was pretty random at best and I found that I wouldn't improve much from week to week. With the systematic approach and fundamentals focused practice, I find myself looking forward to practice each day and seeing improvements daily. Not only that, but I feel good at the start and end of practice. It used to be that I would be worn down by the end of practice where it would even affect the next day. The routines really reinforce each other and create a solid foundation including endurance and range. This has given me much greater confidence in my playing and performing. It's a great feeling to not have to worry before a gig whether I'll "have any lip left" at the end. I'm sure anyone would benefit from lessons with Jeff.
