A Cryptic Tune?

I wish I was more cryptic with the words that I use

It's like being in a jazz band playing rock and roll tunes

The words have a purpose and the melody is clear

But what I'm really saying is taken far from here

I have an ear for music and I sing songs in the shower

But I am never washed fully clean you'll always find a trace

Of the filth that is on my mind, it's dirty and without peace

I used to be a showman playing for the madding crowd

To mellow out their feelings I always spoke my mind

With caution on the saxophone swooning a lullaby 

With rhythm and with the soul when I play the blues they sigh

So the listeners can console and take of what they will

Don't take these words for granted there are lines in-between

I dare you if you will find the meaning behind these words

I am rock and rolling still but the jazz man holds the key

Every other blue tone writer will never be like me

Who wants to sing a happy song where everything is bliss

No one that I've met so far can sing a song like this

They hop and hip and pop and step on everyone's toes

But to be cryptic in your writing lets the reader know

There is more to what you are saying and still more to come

So be poised with readiness for the ultimate surprise

I once played piano in a band of fools who believed in God

But most of them are either doing time or living with their lord

Me I'm going steady but not in the right direction as far as I can say

I need to go back to the beginning to who I used to be

Then block out every note and try to change the key

Then this cryptic tune of mine will be an undefined melody.
