Praying is like playing jazz. The more you pray, the richer your prayer becomes. You can pray alone, but the exciting things happen with fellow pray-ers. It helps to know and trust others, too (although you learn a lot when you pray with new people). Some services are traditional, others creative. Some synagogues are formal, others less so. The Jewish service is built around a set of spiritual themes. Sometimes we all pray in harmony, other times we pray at our own rhythm, at our own volume.
