An article I was reading was mainly about modern RNB and the way it insights violence through two different ways. The first is the lyrics and second is the beat, it is not a constant beat but a broken one. You are more likely to have something kick off a a function where there is a lot of RNB played.
Looking into it further, some of the effects that music can have are:
Motivation - some music is motivational
Relaxation - Chillout music
Aggression - http://www.apa.org/releases/violentsongs.html
Happiness - Music can stimulate your body to produce serotonin (the happiness hormone) and so elevate mood
Boredom - often caused by a track that has been heard too many times and you get bored of it
In order to have the maximum effect, the same type of music needs to be played i.e. playing a mixture of relaxation, aggressive, happy and boring music will leave a person in an emotional mess and they won't enjoy themselves. Hence why I stopped playing chillout/relaxing music at the beginning of a function as background music.
So as a DJ we need to play happy music that gets the serotonin pumping but the problem is finding tracks that give the feel good factor. Through trial and error, I think I now have a pretty good list of tracks that work. Through experimentation, I get less empty dance floors, less people going out for a fag break and lots more appreciation at the end. But I am concentrating more on mixed family functions/weddings/30+ birthdays where you can play more tracks from different genre and avoiding younger parties where they want more modern music played as most of the current chart stuff does not give a feel good factor. There is enough to include as part of a mixed genre function but I haven't identified enough to do a whole evening yet. Teen parties are not my area of expertise so I don't do them.
A track that gives the feel good factor has to have positive happy lyrics. A lot of the tracks that have stood the test of time and get played again and again to give a feel good factor fall under the category of cheese and that is why they probably still get played.
It also explains why sometimes if you don't have many people dancing, you get thanked at the end for a good night and people enjoy themselves. You have probably played the right music to create the happiness factor.
This all came about because I think I got into a rut, playing what I thought should work and it wasn't always working so I decided to find out why. It is easy to get into a routine of doing the same sort of thing at every function and sometimes hard to accept that what you are doing is wrong because you have always done it that way and it is your perception of what a DJ should do.
Now I have got my whole CD collection ripped to a hard drive, it is easier to spend some time listening to tracks and pulling out the one's that I had forgotten about or that I didn't think of but are worthy of inclusion in a set.
Thats my Sunday morning waffle and a little research project that has kept me quiet for a while.
Feedback/comments greatly appreciated
