Research has shown that the music we listen to can directly impact our mood, not that we needed research to tell us that. We already know that sad songs tend to make us feel sad, while uplifting songs tend to make us feel happy. Aggressive music can even make us feel angry.

Just about every genre of music has the ability to change our moods and even change our perceptions of our current situation and our surroundings. No one understands this better than the world’s greatest filmmakers.

They are masters at eliciting the ‘correct’ mood or feeling from audiences by inserting just the right piece of music at the right time to work hand in hand with the visuals.

In other words, a well-designed soundtrack can implant in us the desired atmosphere or mood of a particular scene or character, and make us laugh, cry or get angry as a result.

See How a Movie Scene Mood Changes by Removing the Music
To prove this point, why not put on your favourite romantic or horror film and navigate to your favourite scene that is accompanied by music. Now watch that scene with the sound on and then again with the sound switched off and you’ll see how the mood of the scene is completely lost or at least altered by the absence of music.

One genre of music particularly effective at altering our mood is blues (and blues rock). In fact the very name of this musical genre is based on a mood. Having the ‘blues’ is old time slang for being sad or depressed, which is why sad or depressing themes are the trademark of blues music and the artists that write and perform it.

Blues singers routinely sing about themes such as unhappiness, heartache, depression, sorrow, distress, sadness, dejection, woes, lamentation, wretchedness, gloom, worries, despondency, desolation, misery, melancholy, despair and heartbreak.

This is not to say that if you listen to blues that your mood will change so drastically that you’ll instantly become depressed and try to jump off a bridge. It’ll more likely just put you into a more ‘contemplative’ or ‘thoughtful’ mood than say if you were listening to a foot-tapping polka.

The Blues Can Make Listeners Tap into Their Emotions
In other words, the blues doesn’t necessarily cause listeners to feel down or depressed, but can make them ‘tap into their own emotions.’

And in the case of people that are feeling sad or a little down, the blues (like many other genres of music) can be cathartic like or a relief. But blues has its time and place, which means it’s not the most apt music for all situations or venues.

Have you ever noticed, for instance, how elevator music is usually upbeat and as far from sad or depressing as you’ll likely come across? That’s by design to keep elevator passengers calm and their moods upbeat, particularly those that may have a fear or anxiety of elevators or small spaces in general.

For the same reason you’ll never encounter an elevator playing the music from Jaws or the shower scene from Psycho. If you do, you’re either been pranked or you’ve taken a very wrong turn. Either way, just like the elevator you find yourself in, your mood will go from up to down.

Why Elevators Don’t Play Death Metal
You’ll also rarely find elevators that play the blues, blues rock, death metal or Leonard Cohen because there are far more ‘cheerful’ categories of music to keep passengers as happy. (If an elevator breaks down with people trapped inside it, no type of music no matter how upbeat, will keep the general mood from turning sour in a hurry).

Similarly, most formal or black tie dinners are accompanied by classical music because it’s a genre of music that lends itself to smart, formal or ceremonial gatherings, and thus enhances the general mood. The addition of rap, heavy metal or punk rock would likely have the opposite effect in such an environment, and result in a decline in mood.

The way music has the ability to alter or sway our moods is used to tremendous effect by a variety of industries including land and online casinos. For the best example of this, look no further than their slot machines / online slots.

Slots are typically noisier than a preschool at recess and for good reason. Their sound effects and music are designed to bombard our senses in conjunction with the game’s bright, colourful and bold graphics and, in the case of slot machines, flashing lights to put us in and keep us in a good mood so we keep ‘feeding the machine.’

Online Slots Use Mood Music to Great Effect
Online slots are no different. Each one has a unique theme along with its own music and sound effects to massage your senses and keep you happy and playing. In fact, the soundtrack is big part of every no deposit slot game so check out the most popular ones that are used to great effect.

While not all soundtracks appeal to all players all the time, most have been designed to appeal to the widest audience. That said, many slot fans are not bothered by a game’s music and in the case of online slots, can lower the volume and even switch it off.

Interestingly, a host of top-rated online casino software vendors have produced blues as well as jazz-themed slots. The best of these include The Blues Brothers from Bally; Jazz of the New Orleans from Play 'n Go, In Jazz from Endorphina, Lady in Red from Microgaming and The Jazz Club from Playtech.
