As some of you may know, this is not the first book I have written on the world of the Bass Guitar, in fact I think it is the thirteenth (or something like that). But I felt that I had not created something really and totally (not that previous teaching methods are not!) useful, for those whose goal is to make music their profession, or, at the very least, for those who want to be able to play to the best of their ability, in as many musical contexts as possible. So I'm going to try, premising that I am a bass player by profession, but I do not consider myself a professional bass player. I have only gained about 20 years of experience, gigging, studying, and more. To recap, I will try, with all my might, to give you as much advice as I can, and I will also try to get you to avoid the mistakes (many) that I have made over time!!! So guys, this, rather than a real teaching method, we could define it as a kind of "manual" for optimizing various studies, based, as I said, on my experiences, both as a musician and as a teacher.
