Touchscreen ON while music is played

I would like to have the screen go to the ON position as soon as music is starting to play. So when the music starts to play the screen goes ON and stays ON as long as the music is played, then the screen goes blank after after a time out when the music is finished.
anybody ?

Setup: Volumio on a Raspberry Pi 3B with a pifi dac+ v2.0 and a Touch Screen in a case.
