freestyle
Within the Japanese asalato community, the term freestyle refers to solo improvisations.
creating original variations
One method to begin freestyling is through creating original variations of existing asalato rhythms.
For example, a player can treat a simple groove like lucky chance similar to a drum set groove, but change the last two beats of the groove every four bars, similar to adding a short drum fill at the end of the bar.
signature style
It is highly valued in the Japanese asalato community to have a signature style when freestyling.
