We all have our own playlists and preferences. Why would God not also have His own? Is it only about the lyrics or is music and its rhythm, sound, style, and beat also a message? The music of worship is to be worship music -- defined not by what we find meaningful but by what it says and how it says it. It is also largely congregational -- designed for and used for communal song in response to God and His gifts that are the core and center of what happens on Sunday morning. It seems pretty clear from the Old Testament and especially the Psalms that God has something to say about the music of worship. Even the New Testament references to music are not quite generic but speak to the context and content as well as the purpose of such music. Why now do we think that your favorite radio station or your playlist ought to be reflected in what is sung (or, more accurately, heard) on Sunday morning?
For that matter, I am also not a fan of the cocktail style piano music that puts the melody to a hymn in with the same style, chords, and rolls that one might expect to hear as background music in a bar -- background music designed neither to inspire nor offend but simply to be there in the background in case anyone just might be listening. I do not mean to offend those who write them because I am sure there is a market for them but that is not good church music. As good as the piano is, it is not a melodic instrument designed to support the voice. It is a rhythmic and percussive instrument that uses strings but in a very different way than a violin or cello. If you have to use a piano exclusively, better to play it straight than to make it sound like the piano man who adds a soundtrack to your lonely sips of fine bourbon or who plays unobtrusively while you and your party laugh and drink your wine.
Hymn and chant and high thanksgiving... sings the hymn stanza penned by Marcus Aurelius Clemens Prudentius (348-405). Hymn and chant and high thanksgiving ought to be the norm --not canned music we listen to or praise bands to entertain us or organists who make themselves more than the music they play but the song that lifts the voices to a unity of praise and thanksgiving for what Christ has done and for the fruits of His redeeming work we now receive. This is not simply about borrowing the sound track from secular music but also about stealing the songs from the Contemporary Christian Music station or tracks we listen to online or on our various devices. We do not sing love songs to Jesus but sing of the love Jesus has shown us sinners who deserved nothing of His kindness and mercy but who have received more than we could ever expect or dare to ask by His death and resurrection. Of course, worship has its own music -- the music of the Divine Service and the hymns that make the voices of many into one voice lifted to God with high thanksgiving.
