Hey Tdot, I just let my imagination flow and hum some random melody. When I stumble on some good melody that I like I quickly put it to fl studio piano roll, and than look at the notes and see which scale uses those notes. I'm not that good to tell by ear on what scale a specific melody is on, so I need to analyse. It helps greatly if you have all the scales with its chords written on the paper!
Oh and try humming some known melodies and just improvise on that. Just hum the exact melody of eg. timbaland and go off the track and start improvising. That way you can find some great melodies! And it's not plagiarism! It also helps on improvising the melodies.
Hope it helped
Alright cool thank, I've tried humming to come up with melodies but I find that I only come with good melodies being hummer when I'm not consciously trying to do anything special.
When I try and and hum a melody it's over thought it doesn't work for me. I would try that though, and sometimes the melodies I do hum or to hard for me to put on the keyboard and play it.
