First off..You are doing great.  That is some excellent progress, and I have no doubt that you will have that song sounding excellent by the time you need to perform it.  We believe in you.  You are doing good.

Coolpink, I would guess that the dear husband is *not* a musician himself?

Most people are used to hearing the processed and optimized pablum that the music industry pushes.  They don't realize that it may have taken that pop star a hundred takes to get one good one, and that then a team of experts worked over that little bit of music that was played or sung to fix every tiny little rough spot and sweeten it up.  It is multimillion dollar product and it is simply not allowed to actually have any real rough spots.  By the time anyone hears it with the band or performer "on tour" they will have done it hundreds of times in practice with very good gear and a lot of support/coaching and another team of experts who work to make the live sound consistently excellent.

Or even when hearing a bar band or street busker play, one is hearing the result of what is often a tremendous number of hours of practice.  Probably sounded more than a little rough when they were just starting out.

Fellow musicians will *usually* be more encouraging and supportive, because they go (or have gone at some point) through the same stages of practice and development.  The average person, on the other hand, is sort of trained to think of music (or any art) as something that is easy and effortless.  Maybe you recall an old Dire Straits song, "Money for Nothing"?  Sadly, it portrays an all too common view of musicians.  LOL

Not that it excuses discouraging a spouse who is doing something they love.  

Oh, and if he *is* a musician?   Then he is very naughty (not in a fun sense) and should consider that he has to sleep sometimes and baseball bats are much less expensive than violins.  LOL

But don't let it discourage you.  You are doing great.
