When we strum, we create sonic shapes. Shapes which involve many facets. We experiment our way into realizing our harmonic intentions.
The overall rhythmic sound shape from strumming includes combinations and mixing these things together: Hitting/Missing, Range, Dynamics [volume], Accents, Tempo, Double-timing and Touching [Muting]-Pressing.
We can't possibly micro-manage all of these facets. Our goal is to develop our rhythmic self and skills by training in intelligent ways.
