The DJ sets the mood and atmosphere of the occasion
By carefully mixing the right type of music to what is going on during the event, the DJ can enhance the mood. For example, by playing the appropriate music at the right volume for cocktails/dinner, guests can enjoy their eating and socializing as if they were dining in a fine restaurant. After dinner, appropriate music for dancing (both slow and fast) can be initiated to entice your guests to move to the dance floor, as if they were in an upscale night club or ballroom.
The DJ knows when to change the tempo and style of the music
By carefully watching and analyzing the guests reactions to the music, a good DJ can make the appropriate changes to suit the mood of the audience to keep them dancing and/or entertained. The DJ can also take requests and play them at the proper time, which further enhances the audience/DJ experience.
The DJ acts as a focal point to get things done in an orderly fashion
A DJ can help you, the caterers, photographers, wait staff, and guests make things run smoothly at an event. Whenever something needs to be announced to your audience, the DJ can do the chore. This can include items such as asking people to take their places at their seats, starting the buffet line, the introduction of the bridal party, the announcement of the bride and groom’s first dance, leading the parent’s dances, doing raffle drawings, etc.
The DJ has the professional equipment needed for your affair
The DJ has the right type of audio equipment to play music in a way that will encourage your guests to get up and dance (or allow them to enjoy conversations with other guests). Most importantly, a professional DJ will have backup equipment if anything should fail so your party will keep going and you won’t need to worry.
