When we gather together for corporate worship, the people assembled are engaging with the music at a variety of levels. I like to simplify this into three layers, or sections of a pyramid. At the top of the pyramid, the outermost layer, is the musical content. Some people engage and respond to the music used in worship purely at the musical level: melodies, harmonies, rhythms, and dynamics. The next layer down in the middle is the lyrical content. Some people engage and respond to the music and also recognize that there are lyrics and the lyrics have a quality. They are poetic and have rhyme, meter, and beauty. The bottom layer is the foundation that we want all people to get to. It is the spiritual content. All of the musical and lyrical content being presented is prompting us to recognize the spiritual reality of who God is and what God has done. Our songs in worship are there to move us into participation with God in the work of recreating and renewing the whole world.
