How do I fill a gap with silence, at the beginning of a track, in multi-track mode?

Hey everybody!

I have 2 tracks in multi-track mode ... one is Music and the other is Vocals. The music starts at the beginning and lasts 3 minutes. The vocals don't begin until 10 seconds into the music. I need to insert silence in the beginning of the Vocals, because I will be sending both tracks to a producer and I want the tracks to line up from the beginning. Otherwise, they will have to line up my vocals.

Thanks for any help. :-)
