I honestly believe the best weddings I have been to have had the best bands, singers and DJ's.The type of music you pick can set the tone of your wedding and solidify a theme. And it's the thing people most often remember. Think about what musical genre best reflects your personalities and inspires the ambience you want to create: '70s disco or a romantic string quartet? A throwback big band feel or kick-off-your-shoes rockabilly? The way the music is delivered—by live band or DJ—also affects the atmosphere. The type of music you want may also dictate your decision too—big band sounds are generally best live, for example. There's nothing like a live wedding band to get a crowd excited and create a sense of sophistication. A good bandleader will play the master of ceremonies at your reception, interacting with folks on the dance floor, paying attention to the "feel" of the room and selecting music accordingly.Live music is, well, live. You and your guests will experience the pleasure of a performance. Anything can happen to raise the excitement level, from an infectious horn section interlude to a moving solo. Ideally, you will want to see a DJ or band in action before you commit so you can gauge firsthand the way they dress, improvise and work the crowd. If that's not a possibility ask to see some video of them playing.
