Excuse...

If I seem to you:
     less verbose
     less present
     less substantial posting
You know where my efforts are
     I'm working on a song
     A piece of music
     In six-part harmony
     My most ambitious work
     For they who lifted my spirits
     And brought me to life again
          (I suspect that if it's good enough they'd perform it.)
Most of my efforts will be over the summer
Since having a piano close by would really help!
