I’ll vote no. TL DR: This would only be true if you play what you’re learning by ear with correct technique and not all of us are that intuitive.
I’ve had plenty of people (college music professors included) comment that they thought I had great ears. Nearly my whole life (from age ~5 to now, 38) I’ve played a lot by ear and done formal ear training (solfege) at college. In my formative years, nearly any piece of music I wanted to play that had no sheet music available (this was pre-internet) I had to transcribe myself. That all included songs by Petrucci, Eric Johnson, Steve Vai, Joe Satriani, Joe Pass, Yngwie, Al Di Meola, Brad Paisley and the list goes on. I could learn by ear and play their solos note for note ( …just not up to speed). I’m proud to say I developed really good ears. After all, people tend to get good at what they do an awful lot of, and for several decades I was training my ears for hours most days.
Now contrast that with my technique…that is another story. While I was formally trained as a classical guitarist in college, I never had any lessons before that. So all of my electric guitar playing, picking in particular, is self taught. I am a horribly non-intuitive individual. And even though work ethic is typically a good thing, it was the opposite for me in this situation. Anything that ever seemed difficult for me to play, I never thought of changing my approach or analyzing why it might be difficult. I just thought I needed to work on it more since “practice makes perfect” as the flawed proverb says. I eventually arrived at respectable speeds. On my best days I could play a couple measures of 16ths in the 170bmp range, just before I tensed up and it crumbled. I was pushing an inefficient technique to the max.
Once I found Cracking the Code, that of course changed. I was shown the error of my ways and learned what works, what doesn’t and how fast playing should feel so easy when you do it correctly.
This is my experience. I will say, if I were more intuitive, I’d have a different answer to this question. If my natural inclination when learning an Al Di Meola solo was to adopt a DSX motion since this is the best way to play his stuff, then learning his solos by ear would have had a great impact on my technique. If I then switched over to an Eric Johnson solo and noticed I’d do best with a USX motion, same thing. Now I know plenty will say “You can have just one escape motion and play pretty much everything by rearranging the notes or adding slurs etc. etc. etc.”. Well, yeah. But again, that works if you’re an intuitive person
