YT video's will only confuse you,, everyone has their own style,, so its difficult to decide whose style to follow. Just don't... Minor & Diminished chords are for Trap beats,, but other than that,, find 4/3 notes you like that sounds good together,, play with it & lay it out the way you think sounds best,, use the same notes in a different range of the beat & play with it till you feel it sounds right,, slap some 808's on it,, a hard hittin' kick,, snare & add thin hi-hats. There you have a Trap beat
