Use dimmers to soften overhead lights or simply change a few light bulbs to lower wattage for the evening. Large gatherings can be a little brighter since the level of energy goes up with the level of light. Remember, however, that the goal is to flatter people and create a festive atmosphere. The sound of stimulating conversation is often the main attraction at a party. However, other sounds, such as a crackling fire in the fireplace or meat searing in a hot pan, can also enhance the atmosphere.
Music can be a wonderful addition to a party, either as entertainment or for a background effect.
When using music as a background for smaller parties, be careful that it doesn't become overwhelming. It should never be so loud that it interferes with conversation. Prepare music ahead of time carefully considering both your guests and the atmosphere you wish to create. Either holiday music or light classical music is a good choice for a dinner party while jazz and cheery holiday tunes help to create a lively atmosphere as people mingle and talk. Delight the sense of smell from the moment people walk in the door.
