If you go to 7.14 ish of this video, you can clearly here some kind of keyboard thingy in the background. Im not sure if it's a synthesizer or a keyboard, never played either and don't know much about either.

Are most keyobards capable of that kinda sound ?

Sorry, i understand that this is a n00b question.
A keyboard is just a means of controlling a piano, synth or midi, it's literally just the keys that you press The sound in the song seems to be strings, guess they could be acoustic but it's probably a synth sound that would be sequenced using a keyboard
