Sometimes I wish I could STOP using them! When I hear myself on playback, I find I overplay them.
I'm not quite sure I am following what the OP is talking about. Are you talking about slurring the note into the fourth, as in coming up from underneath? I may already be familiar (and doing this), but I don't understand the OP's question.
When I think of a fifth interval that's the basic power chord, and the fourth interval is the inversion of the same, as in Deep Purple, Smoke on the water. Are you actually talking about 6th intervals here? Eg, a third degree of the scale, played under the octave of the root? Then you harmonize that interval right up or down. If so, yes I dig that sound a lot.
Technically speaking this gospel/soul/R&B rhythm style makes use of sliding and hammered on 3rd's, 4th's, 5th's and sixths. Blues, funk and country players also use sliding tritones quite effectively. Country guys also tend to use bends more than hammer ons - like bending a minor 3rd up to a 4th or even a ma7 to a unison.
hey, i hear ya.
I meant sliding 4ths and 5ths. like all the soul/gospel guys do. get me?
