let me elaborate, im really good at makin melodíes but where I struggle is when I have to make another melody for the breakdown, when I try to make abother melody it just doesnt go with the other melody(the main one). I wanna be able to come up with melodies that complement the other one. sorry for grammar.

if it helps I make similar music to kshmr, or at least try

I agree with knappster, if you can't find a melody that compliments your drop, simply use the one from your drop. Fade it in, or use the same melody on a softer sound such as a pluck.

why not try analyzing other songs ? Porter Robinson - Language got the coolest breakdown imo i studied that then suddenly understood how it works. basically the chord progression decides where the melody will go. if the chord prog changes (not just randomly) then it'll be real smooth

This, if you're stuck, the best thing you can do is analyze songs.

Bro if you have one good melody, then you're pretty much set. Try and build up to it with background chords and stuff that fits around the melody, before you actually start playing the melody.
