Thanks for your thoughts. Tomatis is not a way to learn a language. It is supposed to be a way to train the ear to make language learning easier. I have "learned" Russian using methods you described, and also lived there for a year. But I still feel frustrated that I cannot always catch what people are saying.
There are many threads in this section asking if this or that method works. My opinion is that no method can be successful if it's used in isolation from everything else. Although I have no personal experience with any particular teaching method, I've heard comments from people taught by the Callan Method, and the comments were far from flattering. The classes, they said, would bore them to tears, and they'd always end up feeling they hadn't made any progress at all. I think the only good way to learn a language is to try and soak up as much of the language as possible, from a variety of sources, look up any word that comes to one's mind, do essays on made-up subjects, and - if a stay abroad is not an option - make acquaintances in chat rooms. Also, I think reading specialist books on the relevant language would be a great help.
