I'm having a hard time understand the proper way to play octaves when using a 2 finger right hand style. It becomes very awkward and cumbersome, even on slow passages. What advice can anyone offer to aid this? Also, I am finding conflicting things regarding "raking." When I descend on a scale, I use the finger that just finished playing a note to hit the next string, since it is resting on that string already. Is this the proper way to descend on the strings? I find it to be a cleaner method, but as I read more and more about strict alternation in the right hand, I'm finding online lessons call it bad technique. What is the proper way?
