Are adults harder to teach than kids?
As most know, Kids are like sponges when it comes to new things but they need more monitoring around the issues of practicing and the fine motor skills aspect of playing an instrument. Things like hand and finger placement and arching, posture and issues around relaxing while playing. Adults usually have clearer goals, a good track record at sticking to things and are the ones actually paying for the lessons. So their self expectations are high. They are adults and so the time to practice or the way they organize and prioritize their time can be an issue.
