Who is known as "the father of film music"?

Everyone must father something in life.

interesting clue considering that all the cameras shown in silhouette are ALL still cameras

What musicals or film scores did Max Steiner compose? I am disappointed that it didn't name any in the explanation.

Max was dope.

Until sound film, the sound track was provided live by theatre musicians. Steiner arrived in Hollywood just as movies included their own music.

only name I recognised!
