Variations on a ground Take another five

(Fred wrote: "In former days I was busy with old English manual music, composers as Byrd, Bull, Philips, Farnaby etc. And they wrote sometimes a ground - in fact what we should call now a passacaglia . In the same time I had an interest in the work of Dave Brubeck. The mix of these things is ... this piece. Take five (of Brubeck) is in 5/4, but in these Variations it stands for 5 bars (take another five). The melodic-line is build upon 4x5 bars.")
