Hello Monica, the Granados is different than his other marches, but I like it. I really think this one would sound great with orchestration - the elements are there.
Your
Widmung was an endearing interpretation of this sentimental piece. I agree with all the praise that has been given...
I love the use of candles or dim lighting in a music room, it adds an excellent 19th century salon effect. I have dimmers on the chandelier and pole lamp beside my piano room, and like indirect lighting when it comes to the piano, even for reading music. I don't use a stand lamp any more, but if you're intent on using one for video, try adding dimmer at the outlet end to "
enhance the romance with little finance."

The room and pages seem too bright. Since lamps and candles have different color temperatures, it would be difficult to get both color correct on the video. Using a tungsten lamp instead of a halogen might give a better color balance. The mysticism and artistic motif would be enhanced if the light source was supplied only by candles in the room. The keyboard, fingers, and face would be luminescent against a dark background, just like a Georges de la Tour painting. This is one of my favorite lighting effects. You will have to fiddle with the exposure and white balance settings to dial in the desired dramatic effect on the camera, but it's worth a try next time. I haven't done a video, but have taken pictures with this similar technique.
BTW, your video would make a wonderful ad for Yankee Candle (A chain of candle stores here in New England:) I think they would supply you a lifetime supply of candles if you approached them.

Bravo Monica, for your creative spirit. You always surprise us with something new every time....
