Nailing a take is one thing...nailing the timing perfectly is another.
With some exceptions...you can take 10 drummers, tell them you want a 120 BMP tempo, then let them play for a 4-5 minute song...then put up a 120 BMP click against their playing...
...and then come back to this thread and tell us how many were even close to holding it steady throughout the entire song!
That's assuming that not deviating from 120BPM by some margine is actually a good thing
Also, it's quite telling that you chose 120BPM in you example. I don't think you did it on purpose, but unfortunately it is a tempo that's being ingrained in many of us, as it is also for some odd reason the default tempo of pretty much any DAW/sequencer I've seen.
Now to that...add 4-5 more band memebrs who might already have trouble following the drummer throughout...
If they're having a trouble following the drummer, then they have bigger issues, and I'd have a hard time believing that a click track would save them.
I have yet to hear one valid argument why playing to a click is not possible or so difficult to do
When you put the issue in that manner, there are no good arguments. If you can't play to a click, then you should learn. However...
...so I don't get the objections to it.
The objections to it (at least my objections to it) is NOT whether it's difficult or impossible, but whether it is necessarily the RIGHT thing to do. There is a difference there
You tap your foot when you play
I don't
Since I was trained as a classical pianist, such things were frowned upon
...or you listen to the drummer...or you use a click...it's all the same shit.
I know some clicks just sound crappy...but if you use a real percussion sound that becomes part of the drum sound...and maybe even do it with an accent on the 2nd and 4th beats...or just the 4th....it's no different than when the drummer plays that same percussion.
No argument. I will often lay down a scratch drum track for tempo reference to play to it because personally I need the reference, plus it's much more pleasant to listen to than a simple click. However, there are times when I will not use it... or rather I may have a couple of bars of it going at the beginning of a take, but than have it off so I can play w/o it to make it easier to make intentional and natural tempo changes.
Personally, one of the things I absolutely love about punk music is the crazy tempo changes that occur. And stuff like this has been becoming more and more rare, and I suspect part of this is because we have enslaved ourselves to playing to a click, DAWs themselves make it difficult to do this (especially if you also want to include some MIDI sequences), and we want our club music to be nice and simple 4/4 stompy stomp.
Finally, I recommend you listen to some 19th and early 20th century music played by good artists. It's amazing how a 110 piece orchestra can actually play together, including some nice tempo changes, tight rhythm by following a conductor. Even better, listen to an orchestra such as Il Giardino Armonico, who specialize in Baroque music, do not have a conductor and have such tight timing that will put your click track to shame. And THEN come back to me and tell me that you can't have people play together, and keep a steady tempo w/o a click track.
If they can't, that's because they're a buncha lazy hacks that think they should record before learning how to play.
