This is a page I wanted when I was practicing yesterday— whatever I was doing was hard enough that I wanted to see these written out, all together. They’re simple, so they’re good starting independence rhythms together with more complex ostinatos. Most of the time I don’t actually want the denser practice rhythms found in Syncopation.
Also see my pages of tresillo/cinquillo inversions. Together that all makes a pretty robust, functional independence/comping vocabulary.
