Move Change: notice closer to the bottom of the tune graphic. I was using \begin{center}..\end{center} to centre the tune graphic, followed by the change notice, if any. But this leaves a paragraph gap after the center section and hence a gap between tune graphic and change notice. Change to use figures to position the graphic, include the change notice as a caption, and use {\centering} around the image to centre just the image.
