Beginning around age 5 or 6, I began learning songs from recordings. During my youth, my motives were to learn those individual songs, but (perhaps without realizing it - though I suppose I DID realize that I was becoming quicker and better at it - and noticing more-and-more details) I ended up with a set of skills that - for many university and conservatory music students, as well as graduates and professionals - end up being real stumbling blocks.
It's never too late to delve into this, and as far as "At age blah-blah, the human brain blah-blah"...well..to hell with that mess...MOTIVATION (I very sincerely believe) overcomes MANY obstacles and shortcomings.
This is an OLD fb post of mine, and the other person was a 3rd/4th tier country music singer, who was making his living cleaning and refinishing log houses (and automobiles), and who was receiving some air-play in Europe, but not in the USA. He was an "ok" singer, but had not learned how to play guitar nor keyboard instruments.
That having been said, "Learning/knowing a whole bunch of songs" (or tuba repertoire/solos/excerpts/etc.) is GREAT, but knowing HOW to learn and HOW to interpret-and-master that repertoire (WITHOUT having to necessarily be spoon-fed interpretation of every piece of a repertoire by some teacher/guru) is much more powerful.A c. fifty-year-old man (who's doing some work around here) is wanting me to teach him some stuff about the guitar.
(I showed him some basics the other night...
He has recorded some country songs, actually has had some air-play, and owns a pretty good guitar, but doesn't know how to play it.)
He was getting ready to leave for the week and said, "Show me something I could do with two or three strings"...
...so I racked my brain and thought of that Harrison intro to Here Comes The Sun, and played it for him (very simple) and then went into the song a little bit.
He asked "When did you learn that?" to which I replied "Just now".
He couldn't seem to believe that. I explained to him that "knowledge" is a lot more powerful than "learning a bunch of songs".
