What is this type of music?
 

Hi, I like this type of music, where there are no instruments, but the vocals are doing the beat in the background, basically where it's all vocals rather than vocals paired with drums/guitar/keyboard etcetc. I just love how cool it is that those sounds can be produced from a human

Here's what I mean:

Basically any of the soundtracks in Crash: Twinsanity

and I recently found this type in a Glee song my nephew was playing haha:
Glee Cast - Yeah!

A bit hesitant to put this one on, because it's more beatboxing, but this is the first song I came across as a kid which is mostly just coming from his voice, and I always found it really cool:
Only Human - SNAP!

They can't be all classed as beatboxing, can they?

Any help and similar songs would be appreciated :D

p.s I'm not allowed to post the links for the music vids, sorry for being a noob, lel

Crash: Twinsanity OST is mostly acapella. That Glee song is a cover of an Usher song - not acapella or beatboxing - the Only Human song is definitely beatboxing.

When I type in "acapella" it comes up with songs that have the music completely cut out, and it's just vocals singing with no music. I'm talking about where they have made the music with their voice.
I know the Glee song is a cover, what I'm saying is, a lot of the background track is voiced.

Turbo B from Snap! is a great guy from what I remember.

A capella is a purely vocal performance, even if the vocals are emulating instruments.

What you're describing isn't a genre, if that's what you're wondering. It's simply a style of performing. You could do a capella arrangements for just about any kind of music.
