My friends and I recently formed a band, we've jammed and wrote some tunes. They turned out good. The only problem they're more "metalcore" sounding (Trivium, As I Lay Dying, Unearth). Now as the composer of the band I wanted to pull the band into the direction of Melodic Death Metal bands like In Flames, Enter My Silence, Arch Enemy etc.. so is they're any type of theory I should learn to create riffs and leads?

If anyone could help me that would be awesome.
