I noticed that the song "Somebody I Used to Know" used the wobbly guitar in the refrains. I was wondering if they used it for rhythm on the e’s of the beats ?

What’s the theory behind the vibratos?

;do you notice it on the solo on the e’s of the beat? In (notations) Do they count as 8th 16th or 32nd notes or a pulse?

There are certainly rhythmic aspects to it, yes.

Vibrato and tremolo are basically small adjustments in pitch (and, sometimes, timbre). When these adjustments occur rhythmically, they do create a particular rhythmic background that can be used for musical effect.

There's no real theory, they're just creating rhythmic interest with vibrato and tremolo techniques.


They are not a specific rhythm. They are just an effect to add colour.
