May Melody Keep You Alive! Singing Trough The Tide!

So the St. Cloud Library rejected the idea of me playing a concert there.  I was pretty upset but I brain stormed a while and decided to do a concert at the "skate park" by my St. Cloud appartment.  Just gotta scout things out to find power outlets.  Feeling better about music too.  I jammed on keys earlier and just played through my tricks and ideas an came up with a new one...  I use my right hand for this melody, use any bass progression you want:

C
B
A           X
G                 X
F
E      X
D X
C                        X

P.S.  Happy 19th birthday to me! (This Friday)
