questions about "Say It Right" PLEASE HELP

[veravv]

hey i have to do a project for my class on a pop song, so i picked Say It Right. We have to put down the instruments, melody, rhythm, harmony. can u please help me out!

instrument wise- I hear drums (percussion), guitar, keyboard, some computer generated sound (spacey effect) or maybe it was a keyboard?, vocals used for ad-libs.
harmony- You can hear harmonies in the 2nd verse, and the chorus I think, not sure.
melody- The melody is tricky, I think it's the spacey effect.
rhythm- There are 2 beats per measure

I've been trying to figure out the instrument that occurs right after parts in the song like the beginning where she says "Either you got it.." <sound> or you dont <sound> either you stand <sound> or you fall <sound> In the one video I seen they have the one guy making the sound appear from him...but I don't think that is really the case.

[Loosen Up]

yah that's timbaland just saying "hey....hey....you don't mean nothing at all to me..." and then he does some scatting at the end...
also you could mention something about how they used 4 microphones in the recording studio. and they were all moving around while she was singing, which is why her's and timbaland's voices sound dreamy and it sounds like there are more of them in the song. it probably also added to the spacey sound effect and the echos, although i would agree that that could also be partly due to keyboards and/or a computer...but yeah nelly said all this in an interview, but i can't remember which. ill post again if i find the source...
