MUSIC SELECTION GUIDELINES:
Although couples usually have wide latitude in choosing the music for their wedding ceremony, the pastor and music minister may "veto" your selections for practical or liturgical reasons. In a sense, the whole Church participates in your wedding liturgy, so it's important to ensure that the music is prayerful. The Church offers three criteria for liturgical music that should be applied to your choice of wedding music:
1. Is it prayerful? The purpose of any Catholic liturgy, including a wedding liturgy, is to give glory to God and to sanctify (make holy) the worshipers. Your wedding music should reflect that purpose; in other words, it should help the assembly to pray and to give thanks to God for your marriage. The criteria of prayerfulness is one reason why popular music—including some of the "classic" wedding marches taken from secular operas—is often not permitted.
2. Is it accessible? In other words, will the assembly be able to sing along? In Catholic worship, the assembly (everyone attending the wedding) is not an audience, passively watching events unfold at the altar. Catholic liturgy calls on the assembly to actively participate in the prayer of the Church, including its sung prayer. Doing so is one of the most powerful ways your friends and family can express their love and support for you and your spouse.
3. Is it beautiful? Beauty is a window onto the divine (Catechism #32), so it is not surprising that the Church calls for the music used in its worship to be beautiful. This criteria is obviously somewhat subjective, depending on personal tastes and local culture. Whether your music is beautiful or not may depend less on the particular selection than on the skill of the musicians who sing or play it. A hymn that seemed ho-hum the first time you heard it in church might have great potential in the right hands.
Your music ministers have vast resources at their fingertips and can help you make appropriate selections that fit your vision.
