First off everybody's assessment on auto tune is correct in this thread.
F AUTOTUNE!
There is a psychology behind music. And I agree its largely based around harmonious and dissonance and creating a resolution.
See the brain likes patterns. If the battern is broken rhe brain will try to fill in the missing pieces and see the rest of the shape. When it
finally does, its like an itch that it just scratched. Theres a sense of pleasure and satisfaction.
So you have chords and notes that are harmonious with the key or tonic. The wave forms are all equal fractions of the key or fundamental frequency of
the song. The notes in between are not fractions of that fundamental wave form and there fore are out of phase and break the pattern. The brain
doesnt like that dissonance and broken pattern It now has an itch to scratch. Notes like that that are out of key are often called tension notes for
a reason.
The next note or chord played should either rsmp up that tension to potentiate it, or be back in key and "resolve"
When it resolves and the pattern is making sense again the brain feels relieved and the itch is scratched. Pleasure is felt.
If its all harmonious notes, theres no effect. You need the tension from the dissonance to create like a mental pump to get the effect. Or like a
circuit needs some sort of difference in potential for the juice to flow.
Adding rythems is a connected but different conversation. Sure some other folks here can add to that discussion.
