I just started going to a new bass teacher, and he wants me to work on the OFPF for scales. But, he wants me to stretch without lifting my hand. I have the Ed Friedland bass method where he talks about the OFPF method, and he mentions shifting after using the index and middle fingers so that the ring and pinkie can be hit their target. I have tried to stretch my hand like my bass teacher wants while keeping my whole hand in place, but I don't think it's physically possible with my hand. Are there any others out there that can't physically stretch that far? Am I crazy? Wait, don't answer the last one - I know that answer.
