3- Music:
Play soothing music. Playing some soothing music can contribute to the calm and relaxing atmosphere of the massage. Gentle classical music, or sounds from nature are both good options.
If possible, try to find out what type of music your partner/client enjoys. Remember that the massage is about them, not you, so you should try to cater to their tastes.
Don't play the music too loud, it should be playing very softly in the background. It should add to the experience, not take away from it.
