is the high end sound that's hitting the chords around 2:30 of this video



a synth or a sample?
if it's a sample, what kind of a sample is it? (instrument name, genre)
if it's a synth, what are tips to create that kind of sound?

also, what genre does this music belong to?
(i want to know so i can find similar tracks)
