Huy--You are creating an argument based on loaded language:
- "You either know the tune or you don't. You're either faking or you're not."
- "I see this as a manner of "settling for less" and am curious why it's justified."
- You know your **** or you don't.
Essentially, you are saying, "I have no rational argument." ...Maybe you do, but you aren't making it.
You have admitted that you cannot tell the difference by listening, so you should just come out and say "I think this is important, because I think this is important, and I want everyone to agree with me."
Damonsmith--You said "The subtext of so many of these threads tends be about, making excuses to not work on one thing or another."
The subtext of your comment is that people should not debate the best use of their time, and do what you tell them. However, time is precious and limited, and we should be careful in selecting what we are going to spend it on. Effective practice is about making good choices.
The thing about the relationship between memorization and performance is that there is a diminishing return. The closer you get to 100% memorization, the smaller the improvement in your performance. Perhaps 90% memorization and then spending some time on new techniques will make for better music.
There are many reasons not to waste precious practice time memorizing the RB, one of them being that those tunes are getting a little stale, and jazz audiences will continue to shrink as we continue to flog the RB over and over.
Finally, FWIW, a master teacher at a jazz violin class told my son not to waste his time memorizing music. So, even among the big boys there are differences of opinion on this.
Sometimes a gig may require memorization, but the music does not.
