Is being able to sight read music a good thing?
Yes.
Is it necessary to be a good musician?
Hell no!
Is it necessary to study music theory?
Absolutely hell no!
So far, so good.
Is standard notation for stringed fretted instruments superior to TAB?
Absolutely. Throw away the TAB and make your own choices on fingering and picking. Even better, learn to read the grand staff. I used to do wedding receptions borrowing my wife's piano songbooks and sight-reading it from the beginning.
Standard notation is a far inferior method to convey what should be played when it comes to stringed fretted instruments. Especially since almost all TAB programs include standard notation.
Rubbish. See my earlier remark.
The snobbery from the folks who subtly imply that musicians who don't sight read are somehow less of a musician than readers is repugnant. It's sad to see it still persists on here. I wish I could say I was surprised.
The snobbery is yours. I don't know anyone who believes that readers are better musicians. Too many fabulous musicians who don't read.
Readers often get better gigs because leaders and producers know that we can deliver without wasting time and money—or that we can do it at all.
BTW, I have no problem responding to confrontational nonsense with reality.
