The Peter's Voice sound is best described as eclectic and their musical styles are purposely varied to pull from the wide variety of backgrounds of the members. Styles in the Peter's Voice CDs include folk, rock, Latin, and swing. All Peter's Voice CDs have 12 songs to represent the 12 Apostles of Christ and include a hidden track to explain some aspect of the CD. Although the group is very serious about their music, their CDs, and particularly their concerts, include many light hearted moments since their main goal is to get the audience to enjoy and have fun with the music while praising the Lord.
