Duncan is an excellent drum teacher, especially for grade-school and middle-school aged kids. My 11-year-old son thinks Duncan's great, and as learned a variety of rhythms/beats to prepare him for middle-school band as well as playing along with popular songs. Duncan has an easy, friendly style with kids, and jokes with them to get a smile and put them at ease. That said, he is a serious music teacher, and has my son repeat exercises until he can do them correctly. My son has learned an awful lot in the last year and a half, and really looks forward to his weekly drum lessons with Duncan.
