I will concede that reading is becoming increasingly irrelevant outside of classical circles.
But the only reason I don't get to read very much any more, is because so many of the musicians of this generation are plumb ignorant. And I find the situation sad.
There. I've said it.
I get by in a world where there are no charts any more, because of the ear training and improvisation skills that I learned as a jazz musician- AFTER I learned to read.
But I hate the time we waste in rehearsal, and I especially hate the lost flow and creativity.
That's right, LOST.
When I was younger, a band would run through a new chart once (10 minutes, tops). The rest of the session would be devoted to feel, dynamics, fills, etc.
Nowadays, the whole rehearsal is devoted to figuring out what the $&@?!! the missing chords are on the chord sheet, where the repeats are, etc. No time left at the end of the night to build our own arrangement, or to simply jam...
And after wasting hours of our lives on pitiful details every friggin' week, we still hit the stage tentative and poorly unprepared.
The choice is to spend a few months learning to read, or spend the rest if you life spinning your wheels when it comes to efficient musical communication.
