This may be common knowledge to music theory aficionados, but for many people (including me up until 8 months ago) you may not know this tip. When trying to write hooks, usually for a drop, or anything that relies more on the syncopation and rhythm rather than purely the melody, try experimenting with flatted-seconds or sharped-sevenths. This sounds unconventional to many people as the notes are not in the traditional major and minor scales, but I promise you this trick is something seen in a lot of music. I honestly prefer to hit the flatted second more often than going to the sharped seventh. It kind of creates an energetic, dissonant feeling that drives the melody forward. You can hear an example of it hear in Dannic & Sick Individuals "Feel Your Love" ( https://youtu.be/LPY9CvVsbH8?t=3m3s) (the first 3 notes of the drop). Check out some of your favorite "less-melodic" tracks and see if they do this, I guarantee youll find it in every few songs or so. Hope this helped some people!
