1) Find and save to the desktop the score you plan to use (the short version, or Mark’s annotated one). Then open it.

2) Find and open Mark’s conducting video on YouTube. It will open “in front” of the video. I started with the video because it was visible.

3) Move the cursor to the right margin of the page you are working on (for me, it was Mark’s conducting video) until you have a double-headed arrow. “Left hold” the mouse button (or hold the corner of the touch pad).

4) With the double-headed arrow and a “left hold” on the cursor, you should be able to use the cursor to resize the page. Resize it to left so that it is about half the width of your screen. Mark’s video will be on the left side.

5) Once this page is in place, the score should be partially visible (it has been “lying behind” the conducting video). Click on it and it will “pop” in front.

6) Repeat the double-headed arrow process on the left margin of the score and resize it to the right.

7) You may want to play with the positioning a little. I moved the video so the left side of the YouTube page was “off screen”, leaving Mark visible and more room to expand the score slightly.

8) Once the video is playing, move the cursor to the score, click once to make sure the score is “in front”. Then scroll through the score using the roller ball on the mouse or the touch pad – no more clicking required.
