Anyone Need a Good Vocal Coach?

Last night, on our way home from dinner with friends last night, the boys and I were talking about what our plans are for tonight.  I told him that daddy and I would be singing the National Anthem at a festival in a neighboring suburb.  (Apparently we're opening for the Little River Band....I used to have one of their CDs when I was in high school.  Cool!) Anyway, Cody asked, "What does the National Anthem sound like again?"  I decided this was a good opportunity to practice it , and I started to sing it.  

When I got to the end, there was nothing but silence.  A couple of seconds later, Cody said (in a very matter of fact way), "Well, mom, it was really good until you got to the end. "  

"Oh," I said.  "What was wrong with the end?"

"Well, it was that note...the high one."

"Uh. huh.  I see.  And what was wrong with it?"

"Your pitch, mom.  It didn't sound very good."

"Yes, well.  Let me try it again and see if I can do it better this time."

"Okay, mom.  I think that would be a good idea."

I sang the end again and this time, I sat up straight and tried to use more support at 10 p.m. while driving the minivan in a blinding rainstorm so I might impress my son.

"Oh yes, mom.  Sooooo much better."

I think I just found myself a good vocal coach.  Do you think it matters that he's only six?
