This is a special crossword where every instance of any of DO-RE-MI-FA-SO-LA-TI must be entered into a single square. Hit ESC to activate the rebus function. For example, SOLD OUT would be entered in five squares as SO-L-DO-U-T.
Wow! This was really well-done. I was a bit skeptical about the constructor's note, but then when I saw the density of rebus squares I totally agreed with the choice.
