Re: What do you consider to be a wast of time ?
I have to respectfully disagree. Sure, playing Body and Soul in E may never show up in real life, but there is a lot to be gained from being able to play it in E - namely the effect it would have on your ear training. To me, playing in all 12 keys is more of an ear-training exercise than a music memorization exercise...
Yes, that's why I find playing
licks in 12 keys very important, you can easily run through a lick in 12 keys in one practice session.
If you play only one horn and you practice 8 hours a day, then learning all your repertoire in 12 keys is feasible.
If, like myself, you're a doubler and you work on being equally fluent on all of your instruments, spending all your time on one tune in different keys is not the most efficient use of your practice time.
I did at one point, when I was younger, learn Donna Lee in 12 keys, but I can't imagine doing that with the over 200 tunes I have memorized.
Once again, I was referring to the other thread by using the term "waste of time", maybe "least efficient use of time" would have been better.
If some of you are actually learning their repertoire in all keys, you have my admiration.
