I'm sure this is done a lot commercially but these are just tips if you're decent at doing notes and you want to sing the chorus for your tracks. I don't know shit about notes so I'm going to explain it as simply as I can. I deconstructed by ear Bobby Brown's chorus on "My Prerogative" because I thought his voice was really average so I wanted to know what processes he used to make his final product. I KNOW I'm not a good singer btw lol. This was done with Cool Edit Pro 2.0 1. I started with the main voice you hear above the harmonized notes, all I added was reverb to that one. (Effects > Delay Effects > Reverb > Tight and Close) 2. Then I did an (Alto? Do?) note which is the main part of the harmony. I didn't sing this well at all but it doesn't really matter. 3. After the high note I did two low ones. The first low note I did is just the lowest octave you can go for the harmony without it sounding like shit. And the loudest low note you hear that sounds kind of "robotic" I just did to the best of my ability and then lowered the pitch. (Effects > Time/Pitch > Stretch% 102/Pitch Shift: Splicing Frequency 32 Hz Overlapping 25%. High Precision) 5. I added a Falsetto (sing with a head voice) note but I don't think it was really necessary. 6. After I recorded all of my layers I went to Effects > Delay Effects > Flanger > Detuner and added it to all of them EXCEPT the main one you hear above the harmony. The point of this is making them "become one" because without it they don't blend well at all (because you can't actually sing lol) And this is the product: Mine: Download Technology amazing mp3 Bobby Brown's: YouTube - Bobby Brown - My Prerogative [HQ] I'm sure people with better voices can make it sound a lot better than I can but you get the drift.
