Writing bombastic orchestral tracks titled “epic music” isn’t the key. Creativity is.
Good at writing epic music? Great! But you need a diverse portfolio. You are not going to stand out by doing the exact same thing as everyone else trying to break in. In reality, most game developers who are after epic music likely already have a composer to do the job that they’ve worked with before they made games with a legitimate budget. If they don’t have someone, the budget developers can quickly find an established “epic composer” anywhere, and their first choice won’t be an aspiring composer without any commercial game soundtracks to back them up.
I didn’t catch the attention of who became the first game developer to recruit me by writing something big and bombastic. He contacted me after hearing a Haydn-inspired waltz I wrote chamber strings. Why? Because his game needed that sound.
The game developers you might have a shot with probably don’t need epic. What they really want is something that fits the vision they have for their game. And looking ahead, a creative, possibly unique soundtrack will ultimately make you sound out than doing what everyone else is doing.
Ultimately, be creative. White a traditional choral piece, a composition with an untraditional orchestral set up, a ballade for cuckoo clocks, you name it.
Limiting yourself to a big sound won’t help you. Diversifying your portfolio most definitely will.
