Making chords fun

I'm studying an online course, which teaches how to play rhytms and riffs using simple major chords. For example you can play a rhytm used in many popular songs with C, Am, F and G chords, all in the C major scale.

Just by playing the root note of the chord with the left hand and the whole chord with the right. Goes like this:

LH: C (half note, octave below middle C) + RH: C chord (start on middle C, quarter notes.)
LH: A (half note, octave below) + RH: Am chord (start on A to the left of middle C, quarter notes.)
LH: F (half note, octave below) + RH: F chord (quarter notes.)
LH: G (half note, octave below) + RH: G chord (quarter notes.)

One more thing. You start on the left hand note, the pattern is left: half note + right: quarter rest, quarter note chord. Which means you start with the right hand after you've held the left hand note for 50% of the time (50% of a half note is a quarter note.)

Remember, you're moving down the keyboard, to the left. Try this, sounds great. Will put in more riffs as I discover them, you can too if you know about them.

Looks like this on the staff:

Why not just play them in the left hand? Freeing the right hand for whatever.

That's another way to do it. The course covers blues scales in some of the later books. Jytte, how about setting up an underpage on your site with useful riffs and improvisation exercises? Just an idea to think about.
