Reply to Reading/Learning how to do Progressive House melodys?

I've been getting deep into production lately learning all the features of FL first by remaking a few dozen tracks then making my own with a very basic melodys.

My target style is something of Avicii mixed with SHM and elements of similiar artists

Good melody made into a big sound

Im no keyboard player and my only real way to make a melody thats better than what i have is spend the day wacking at my keyboard till i get something close to what i want, but it still does'nt sound right and i can't get it to work out it just sounds wrong and im not making anything good.

i believe its time to get some books but im not really sure what im trying to learn, chord progressions, melodys? just the basics thats going to give me knowledge to make some good progressions i have ideas on how i want them to go but when i go lower down the keyboards to make the sound fuller it just sounds more hard and thuddy rather than full and progressive.
