Let's put together straight eighth notes with dotted eighth notes and sixteenths and discuss them in relation to our feet tapping or patting. Straight eighth notes fall directly on the downbeats and upbeats of the beat or the pulse of dance music. Typically your foot naturally taps or pats in time to the music. When two or more eighth notes are to be played in a groove, be aware that your foot naturally "pats" or strikes the ground on the downbeat of the music, and then naturally rises to the top of it's natural pivot swing before returning to the ground. You are naturally and instinctively keeping time with your foot. At the very top of the rising motion the next upbeat or straight eighth note will occur.
Just after that straight eighth there is still room for the final sixteenth note in a grouping of four sixteenth notes. Learn to feel that last little sixteenth as well as the straight eighth note just before it in relation to your foot pats. You can anticipate the next measure or the next phrase by either this straight eighth note or by the sixteenth note after it. Learn to feel the difference.
