George Gershwin the American composer wrote a terrific little piece "Lullaby" for piano (here it is) and then "orchestrated" it for string quartet. (here). If you have a few minutes, listen to both versions...the original for piano is a whole lot different although it is EXACTLY the same notes.
There was a debate and a howl that went on when Turner Movies started colorizing the old black and white movies. Remember? There has been a similar debate and furor in the music biz for a couple centuries now.
Just something that might be of interest.
