I did none of these things and yet learned how to play others songs. Funny thing is, I'm pretty sure that I woulda had a better/easier time doing this stuff. Admittedly, I was lazy with respect to that stuff. I mean, I was a hard core practicer back in the day so I wasn't lazy but I found the who listening over and over process tedious. Boo hoo for me...I think because I had a good sound memory, I could get by well enough. Wished I would have tried harder though. I'm sure that my cover version (in the cover band days) were not always note perfect. Ya know, I had a good ear and leaned on it as my crutch.
I think to the point of the opening post, these tools make it much easier to do this stuff. Man, I woulda loved to have all this back then. Mighta helped me with my lazy tendencies. For that matter, being here at GT and really back filling the theory that I skipped oh-so-long ago has been great.
Wow was I a big baby back in the day.
