Just some short improvisations all in the same key of G (though one does a bit of Em). I didn't realise the keyboard compass ran out so soon so in one piece there is suddenly a gap in the melody. The previous two improvisations I uploaded were also in G so I guess this is actually a set of seven.
I'm no master improviser - I couldn't create a fugue on the fly but as Daniel Roth says everyone should be able to make something short to fill a gap in a service etc. So it is something I like to practice, or often just idly play away and let stuff sink in sub-consciously what I like or don't like.
