.....I've seen they always instruct to play 1-3-5 triads with the pinky, middle and thumb or vice versa. However, I've noticed some players use their pinky, ring, and pointer on their left hand or their thumb, pointer, and ring on the right.Which is the "right" way?
To me, it makes no sense for a book or teacher to make a student learn to play one way which may be easier at the time and then try to make them change things up down the road.
