Ominous Latin Chanting/Playing With

Basic Trope: As the battle draws near, the music tunes up, with a choir as the lead vocals.
 * Straight: As Lizardax and Bob draw their swords to lock in mortal combat the music whips into frenzy, topped off with an epic chanting chior.
 * Exaggerated: The choir is so loud that it drowns out any other sound while everything is devastated with an epic Earthshattering Kaboom.
 * The choir is obviously the part that the producer blew the budget into, making it the only memorable part of the movie/anime/videogame/what have you.
 * Justified: Bob has kidnapped a chior, or the epic battle is taking place in a church during choir practice.
 * The chants are actually part of a magic ritual that either empowers Lizardax or turns Bob into a One Winged Angel.
 * Inverted: A calm scene is accompanied by a Cherubic Choir.
 * The people from the choir are fighting each other while Bob and Lizardax are the ones singing.
 * Subverted: The Latin choir is only the opening to what is otherwise a choir-less battle tune.
 * Double Subverted: ...but it returns when the enemy goes One Winged Angel.
 * Parodied: The Choir can be clearly seen in the background, or the choir can't carry a tune.
 * The choir uses various profanities in their lyrics as a Bilingual Bonus.
 * The Choir uses Canis Latinicus.
 * Deconstructed: The music is clearly building towards epic points in tone, tied to moments in the battle, but since there is no choir to point the high points out, the song feels hollow and empty...
 * Reconstructed: ... Until the battle breaks into another room, and then choir comes in.
 * Zig Zagged: Every time there is a sword strike or hit landed the choir chants a note, going on and off as the battle progresses.
 * Averted: There is no music during the action sequence, or the rhythmic drone of industrial machinery.
 * A different type of music is playing during the scene.
 * Enforced: "Epic faux-Latin chanting Choir: Accept no substitutes."
 * The creator knows Latin, so he can make it real.
 * Lampshaded: "So we've got Benedictine monks living in the floorboards, unfortunately. We have set some traps with fresh bread and brandy, though..."
 * Invoked: "This epic battle is one for the ages, but it's missing something. I know! Let's add an epic faux-Latin chanting choir!"
 * Defied: "Let's use an AC/DC song for the final battle."
 * Discussed: "Wait, I think I can get my local church choir to illistrate our epic battle, through music."
 * Conversed: "The chanting is nice, but I'd have prefered Sea of Sorrow by Alice in Chains."
 * Played For Laughs: The choir members get in the way of the action, and their singing drowns out the combatants' smack talk. Eventually the frustrated Bob and Lizardax nod to each other, cut down the choir, and go to the tavern together for some ale.
