Origin is based on an ostinato bass line that sets the feeling and emotion of the composition. The ostinato also makes the piece pulsate.  This primal feel builds in momentum throughout the composition. The chord symbols are added for the advanced players enjoyment and teacher accompaniment. Additionally the student will find that the sustaining quality of the ostinato gives a strong base to launch out with new musical ideas. This is a good piece for exploring. Even isolating small sections can make for a comfortable and inspiring feel for creating a unique personal sound.
