I've been playing with Rayman Origins game and I wondering what is the instrument that sounds in it. You can hear it in Jibberish Jungle ~ The Darktoon Chase.
It's the first one that sounds.
I think is an Australian aboriginal instrument.
A lot of the comments think it's a jews harp but I don't think it's a real instrument at all.
A jews harp has a lot more 'twang' in it & though you can kind of 'speak' whilst playing it, you can't get that kind of quick-change filter detail that I'm hearing.
I think it's one of two possibilities
a synthesiser played through a talk box
The two most famous exponents of this were Peter Frampton who used guitar, & directly influenced by Frampton, Roger Troutman, who used a synth instead.
Peter Frampton, Do You Feel Like We Do - tagged to start at the drop solo 5:50
Roger Troutman interview - he starts playing at about 30s, but it's well worth hearing the preamble.
History of Talkbox, Vocoder, and Autotune [rather lumpily, but contains some good references] runs the entire musical history using clips from as far back as the 30s. Includes Frampton & Troutman. Ends up on autotune, which isn't relevant to this particular question.
