What is the exact name of a voice free version of a vocal music?

Question

My main goal is searching in google for some sort of rock musics, I want the best keyword for search.

My question: What is the name of a voice free version of a vocal music?

Is that instrumental? or is there is a more specific name for it?

Answer 1

You can look for "Instrumental Version" or "Karaoke Version".

In the reggae world, these tracks, often on the B-side of a 7-inch single, can be referred as "Version", "Dub", or "Riddim".

_{off topic: In case you don't find the song you want, you can try to remove the voice of your track (with Audacity for example). You can also check on Sound SE.}
