Well, I remember Mel Torme totally sucked playing the role of a gang leader in some old black and white movie where he got beat up by Paul Anka. But that's not really the point.
Pitch correction can be used to make overly dramatic singers sound more subtle than they really are. Sure, that's cheating, but I'm a "win if you can, lose if you must, but always cheat" kind of guy.
First off, Casting Mel Torme as a gang leader, someone with that weak a double chin, not a good idea.
OK. I was asked to "let all this go" I agreed with Mr. Campbell and thought he was right. It seemed earlier in a post that he agreed with me, that my drummer was fixing stuff that wasn't broken. I looked up his bass influences that included Steve Swallow--one of mine. That gives me pause to think--not sure what.
But on the subject of voice correction:
15 months ago my 32 1/2 year old Blue Fronted Amazon died unexpectedly. I had the expectation he'd outlive me. I was so painful & traumatic for me that I couldn't spend much time in my trailer alone. My trailer, formerly had been picture perfect place for the two of us. After the bird's death, I couldn't be alone in the trailer. It was morbid, almost haunted.
I spent all my evenings out with my laptop, emailing just about every person I know--just to distract myself from the loss & trauma. Anything to avoid going home to my empty trailer.
First it was Starbucks, then it was Applebee's, where I used the WiFi until I was kicked out at closing. At Applebee's they played lots of fairly current pop stuff. Most of it I would describe as empty, substance less, banal beyond description.
There was one tune played at Applebees that pops in my head now. " I only muss you when I'm breathing". There were others. I'm not sure what pop sub genre those tunes can be categorized as. Not R & B.
I found nearly all those Applebee tune selections offensive. Intolerable. All of them marked by a relentlessly aggressive electronics beat that I felt assaulted by. Another salient feature of that music was banality, excessive simplicity (to the point of being way too predictable). Yes, I believe that for music to be meaningful, significant, some goal oriented tendencies must be suppressed. There has to be some uncertainty to generate tension. (Great book, "Emotion & Meaning in Music" by the Leonard B. Meyer, I'd highly recommend.)
Of course, most of these banal tunes had pitch correction. The .mechanical & nasal quality of the pitch corrected vocals offended me even more. It got offensive. About a month after my birds passing I was so sick of being assaulted, smacked over the head by that loud, rowdy, offensive garbage at Applebee's, that I simply started going home to my empty, spooky trailer.
As for your argument that voice correction can mask deficiencies of 'overly dramatic' singers? My counter argument is that if an electric devise is needed to mask any of a singers shortcomings, don't perform with that singer & don't go to their performances. There are lots of really good vocalists out there, give THEM a chance.
Conversely, if pitch correction can & will mask the negative qualities of poor singers, then it will just as effectively mask good qualities of singers that actually are skilled & refined. Starting with vocal timbre/quality, voice correction will impart a nasal twangy quality that wasn't originally present, , and isn't desirable. (Just listen to Shania Twain sing her last hit, 'Forever & Always'. Nice song, touching video, but the use voice correction was a big mistake in the interest of being trendy & gimmicky. Should've kept it organic.) Anybody think that tune's better because of voice correction?
Voice correction not only alters (even kills) the timbre of a nice voice, vibrato is eliminated (good vocalists spend years cultivating an expressive vibrato) & subtly of refinement of phrasing is also lost.
I really do aspire to play Brazilian jazz, even Bossa Nova. I love it! I'm crazy about Flora Purim, Eliane Elias, even Lani Hall & Astrid Gilberto. I will never be good enough to play with the likes of Purim, who's a monster, nor will I be good enough to play with a pianist as skilled as Elaine Elias ( her bassist husband Marc Johnson's one lucky mo-fo let me tell ya). (But it's conceivable that I could get to perform with a "poor man's' Lani Hall or Astrid Gilberto). Can anyone out there say that any of these Brazilian jazz singers (hardcore or Bossa Nova) can benefit from voice correction. Voice correction would KILL the genre.
Voice correction I think is more limited to a certain modern type of pop genre, & if it's your cup of tea, fine. Not mine! In my world, learn to sing in tune or don't sing, & being able to play in rhythm without the crutch of a metronome is the price of admission to perform at a semi-pro level.
