From forum discussions it seems that teachers in the US often used published bass methods books. Here in Denmark I've had 4 guitar teachers, 2 piano teachers and now a bass teacher, and none ofte them have used published methods books - although all were dedicated teachers. My teacher of classical guitar had made - and even published - some good material himself, with good progression in difficulty (so I learned to read music) and enjoyable melodies (own compositions and simplified small classical pieces), but ran out of material one day, and then used half of each session to search for suitable material. Also, we never practiced scales or right hand technique. I think it is a consequence of a Danish pedagogical tradition (back to the principles of Grundtvig and the "folk high schools" more than 150 years ago and an ideal of spoken teaching - "living word") and maybe an ideal of "creativity". What are the experiences in other countries, and does it in fact work better using published bass method books?
