Harp to a Harmonica

If I was an instrument

Just currently crafted

As I am

 The old sounds would come from my fresh body

 And startle those near

My simple, small, structure

Should not produce such a sound

And challenge everyone else for attention

That`s not my job

 I Can match with anyone though

I am useful

I am classic

I tune into melancholy jail blues

But I can find upbeats in downs

Can find a way to drown in happiness instead

If I wish it
