How do you guys go about turning melodies into songs?

Questions about producing? Ask them here.
Right now I've got more melodies than I know what to do with, and yet I haven't really gotten much progress into another song.

Do you guys use many different melodies? Or repeat the same one with minor changes? And what types of timbre work best for roles such as a background bass, a lead instrument, etc. Any other advice you'd like to give for turning melodies into songs?

I need all the help I can get, thank you guys

EDIT:
Here's some sample melodies I made if anyone wants to take a look:

That guy has more good vids, one is about making it sound less, like its made on a computer.
In that vid he is exactly doing what I learned from musicbear, change the velocities of some notes.

This link is to a vid about song structure.

What works best for me is trying and keep trying. I am prob now around 2- 3 years seriously trying to make music.
I still learn new things almost everyday.
In my musical journey, sometimes I repeat the same melodies.
And in other songs, I repeat the same melody, that has a few notes changed.
Or, alter the synths frequency dial/knob, to make the melody, have a different sound
or sound like a different instrument.

In the case of Timbre, for background bass+lead instrument etc, it depends
on how I want the song to sound.

Tip: Make a melody and make a tune, based on that melody. Ha! Ha! :D
That's an almost easy way, to use melodies you have made.

And if you can't find a certain synth sound for a melody, don't be afraid to make a synth sound
from scratch. :)
As Gps said -Structure!
All genres has a structure. It is always advisable to work inside those rules as a beginner. It makes the audience 'happy' when they recognize the music, as they expect to recognize it
So study structure. Listen to a lot of songs, in the genre you like to be part of, and learn how the structure of the good one are.
Dont copy! Be yourself, but dont be avantgarde or spooky, because peeps wont understand your music (Unless you are a super freak genius, and give birth to the next great thing :P
-and dont reuse phrases ..its ..bad (imo
The only thing to do is to do it, to go, now, not tomorrow. And if you don't know what to do, do it anyway, do something, anything. The main thing is first to light your mental engine, to heat your imagination a little, and then you will not think about it anymore because you will be busy writing your track.

If a particular sentiment, or a particular idea, has accompanied the writing of your melody, plunge again into that feeling, this idea and do something, anything.

As Gps and musikbear have said, structuring can be a solution to develop a melody. Define the main parts of the track: Intro = 8 measures, Part1 = 16 measurements, etc.

Another solution for starting from a melody: give yourself constraints, invent yourself binding rules. And if necessary, formulate them, with words.

For example, your melody: A F B A F - A A F B A F.
Constraint 1: Another synth will have to use part of the notes of the melody from the ninth measure.
Constraint 2: the bass will play with the notes F.
Constraint 3: the hats will start playing on the A-notes to the third bar.
Constraint 4: etc.

Advance by trial-error, placement-correction, etc. Make it.

Word of a procrastinator :lol:
