Silence.

It is that silence that occurs before the first note. The silence of anticipation. In a moment the hall will be filled with music. The whole place will burst into a firework of sounds. One last moment of waiting for the music.
That's why the picture is almost white. The sounds have not yet filled this space with color. Only this ridiculous looking wizard is filled with color.
Normally you don't see the conductor in his full height. Especially since conductors haven't dressed like this in a long time. This retro type, as you may have already noticed.

It's like the anticipation of Christmas.
