melodies from within

I used to put down notes of a melody, never heard of,
that came to me from within while walking or resting.
Might have accumulated about 25+ passages over the years.
Have been thinking that perhaps one day
I may write songs from some of them.

Two hours ago while I was grocery-shopping,
the latest one sounded off in my head.
This time it is almost like the finale of some symphony,
about 1/3-complete, and I like it; it is of Schumann's style.

But, I told myself, that I will no longer put down
the melodies emerging from my heart; let them pass.
For that nobody can I sing to; why bother?
