I do not know what it is about the use of drums and horns in music that make me want to put on a horned helmet*, grab a sword, and charge a castle. But I like it. The only problem is that sometimes it feels too epic for a “normal” combat.
This kind of music should be saved for that BIG moment when your characters are assaulting the the fortress of the evil emperor. This is the soundtrack of thrilling heroics and epic battles, of great heroes and diabolic villains. Your players should be inspired to greater acts of heroism than normal with this in their ears.
Be aware that this may result in more character death than normal, but heroic sacrifices are still heroic and will be talked about for many sessions to come!
* I am aware that a horned helmet is easy to grab in melee combat, so it would not be a good choice to wear…but come on…rule of cool!
