Recently I went to a workshop on electric guitar. Between several subjects, the presenter talked about dynamics with distortion.
He said that you can use palm mute to create the effect of a "growing melody". For example, you start your song with a full palm mute, and you keep going slowly releasing your hand from the strings during the time until you achieve a "full open sound" (just before a chorus, for example).
I understand that maybe with heavy distortion it's not really dynamics in terms of "amplitude" that we're talking about, but I couldn't think of any other techniques that could have a similar effect of dynamics. The subjects in the workshop changed and I forgot to ask my question:
What other techniques you can use on electric guitar with distortion to bring something similar to "dynamics" to your sound?
