I don't think there's anything lazy about not doing something until you find a need to do it. I've lived my whole life this way and I also work my butt off to make sure I'm prepared for rehearsals, shows, auditions, you name it. Nobody's ever accused me of laziness because I didn't do esoteric study of things that I would never apply.
But here's the thing - everyone learns differently. I learn based on motivation. During the lockdown I tried, twice, to sit down with an instructional book and brush up my reading in the bass clef. But because I had no practical application for that at the time, I was not motivated to continue.
Right now I'm doing that same study in that same book because I do have motivation - I'm starting a new course of study and I want to be able to read efficiently enough to not waste too much time. So when I have a good enough reason, I do things.
Now, one could say that being able to read can help me learn music that I want to play, which is a practical application, but my ear will always be faster than my eyes on this so for a lot of people that's probably true, but it's not true for me. I can already read well enough to know that a lot of the transcriptions I do look at are wrong, though.
I just had this debate earlier in the week here and I agree completely… I weigh in on the “must read standard notation” on the third page….
How do you play “Any Way You Want It”?
