Demonic Illusion: Deafening Wolf Song

Demonic Illusion: Deafening Wolf Song  ( 幻・聾する狼歌曲, Magen: Rousuru Ookamikakyoku) is the signature sound-based genjutsu of the Inuzuka Clan.

Overview
The genjutsu itself is a lost art among the pack; even the most influential members of the clan are unbeknownst of its existence. The technique was developed sometime in the Warren States Era, before the Inuzuka had began their focus on Taijutsu as their primary focal point in terms of combat. The genjutsu is capable of targeting over hundreds of people; any and all of those who hear it's melody are subject to falling prey to the illusion.

Weaknesses
Akin to both the power and chakra required to effectively cast this technique, it takes a considerable amount of time to prepare, often rendering it ineffecient for direct confrontation. Also, because the technique is sound based, it gives off the user's location.

Trivia

 * This technique was the very first technique developed entirely on the author's phone.
