Can musicians use digital recording and editing to "cheat" by making them sound better?
Why, yes. Editing out a flub or a weakly hit and barely audible bass guitar note that would otherwise break up the dynamic flow of the piece and replacing it with the same note from elsewhere in the performance makes the whole sound better. In the early days of recording, if one person made a tiny error, an otherwise great take had to be scrapped and started over. I see no virtue in that. But it's not cheating and by the end of the 50s, EMI were already doing 'drop ins' with a second tape machine to fix tiny errors.
Is copy & paste, pitch correction, or even overdubbing - cheating?
I was doing a song with a friend in which he was drumming and I was doing a guide guitar. We got down a great take, it had the requisite drum feel and I was happy with it. It was only when, a week or so later, I looked at the lyric sheet, that I realized we'd forgotten a verse ! Well, forget about dragging my mate back, I wanted to lay down the guitars there and then. I wasn't up for waiting a month for him to come down. So I just copied and inserted one of the verses. I made sure all the other instruments that go on the copied verse are sufficiently different and distracting so you'd never know.
Personally, I don't use pitch correction because I make people sing ! If they miss the note, we do it again. But I have no problem with it in principle. A friend of mine had a friend of ours from Zambia doing some vocals and she missed a couple of notes but had flown home by the time he could get around to working on anything. Pitch correction was essential. I just hate it when it's deliberately used as an effect {it's valid to use it that way and my dislike is purely personal, the same way I dislike black or red nail varnish on a woman}. Otherwise, I never know when it's been used !
Many home recorders are like DIY people. We are not often people who do this for a living. But given some time and thought
that is not afforded to a pro, home recorders can come up with stuff that is easilly the equal and sometimes better than their full time counterparts. Because one's stuff is at home and you can afford to strike when inspiration hits, you have no choice but to overdub. So no, it isn't cheating. An interesting question would be "If you had every instrumentalist and vocalist at your disposal whenever you wanted and they were willing to help out and rehearse, would you still overdub ?"
Is it fair to present the listener with an "unnatural" performance? Where do you draw the line?
Is it natural to fly through the sky from one country to another ? Is it natural to communicate in seconds with people on the other side of the world ? Is it natural to have a band play it's songs in your van or car or kitchen ? Is a plank of wood with metal strings being fashioned into notes natural ?
'Natural' doesn't come into it. Turning on a telly or a stereo is arguably unnatural. Printing or surfing the net equally so.
The listener isn't concerned with 'natural' or 'unnatural', but 'like' and 'dislike'.
I don't know where I draw the line but when and where I do, it will be according to my own likes and dislikes, as irrational and arbitary as they may be.
And if no post-performance manipulation can make someone sound better, why not?
Well, to be honest with you, I don't think it's a 'given' that post performance manipulation makes someone sound better. Sometimes, it has the opposite effect. Sometimes it can bring out timbres that become exaggerated and can really irritate. On various instruments, post performance manipulation can be a positive downer. Often I've left something raw after trying out various things because it just sounds better the way it was ! All the things we do to drums don't guarantee a great sound. Sometimes, they just sound better raw and uncontrolled and dynamic.
I think sometimes, it's just a mindset we get into, "must do this and that to it".
