How to emphasize lower notes in a chord?

So I find that when I create a chord, and when chords exist in general, the highest note is often the one that's heard. However, in some of the songs I want to work with, the lower note in the chord is the melody. I've worked with velocity before and understand it, but I don't know how to make the velocity of each note in the chord different, as that's the only solution I thought of. Does anyone know of a better way to do it, or how to individually change velocity if that's the only way?

I don't think uploading a score is necessary, as it's literally any chord this can work with. I want the lower note to sound out, unlike how the highest note always seems to become what the chord sounds like.
