To play or solo over
your Ostinato,you will have to build up your co-ordination.
Co-ordination is not
free and "Here is where you start payin" ( you know like that Fame series,but no leg warmers ! )
:" You must earn the
right to play it, and if you can't play it you can not perform it."
So to build up your
co-ordination chops work through the variations over the top of your pattern.
At least try the last
one :)
