How to make techno

in techno I really like the groove and the bass it really drives the track but then how should I do if I want to create a synth above that?a “lead” or a “melody” .I hear some tracks on beatport that have a synth on them and it really makes the track more beautifull…br
ex:maceo plex - conjure dreams (simply 3 notes on top but really pushes the track not being just drums and bass)
