How long have you been watching? I don't think they've edited out the music. The period of time when the readings and eulogies were given was just a long period without music.

I specifically wanted to hear the tenor singing Ave Maria. I have been watching continuously since they took the casket from the Rotunda. The tenor sings later ... I hope they show that. And then the Battle Hymn (a favorite) ... I hope they include that.
