Candlelight 

For a relaxing or for a romantic eve, try lighting a variety of candles. Votives, tapers, tealights, as well as a scented candle in a container. Either have all the lamps off or on the lowest setting. You will instantly find your heart rate dropping a few beats as the mood you have set is incredibly inviting as well as relaxing. Turn on jazz or classical music. Enjoy a meal or just enjoy the beauty you have created.
