The regular rhythm and upbeat tunes of military music or marching bands positively affect your mood even if you don't actually 'enjoy' listening to it.

Mood reflects the biology of the brain. How you feel is affected by the chemicals in the brain, and these are the same chemicals that form the basis of mood-altering drugs. You may use yoga, meditation, cognitive behaviour therapy (CBT) or exercise to alter your mood, or revert to healthy eating, regular exercise and getting enough sleep.

All moods have a cause. If you change the root cause, then your mood will follow suit. Furthermore, mood is a choice. It may not be a completely free choice, but you can choose which mood you spend the most time in.
