When playing a bard with a Lute I can imagine the magic coming from the Lute, but how does the Bass cannon Bard "Aim" her magic. As a tiefling maybe she could use her tail? All ideas are welcomed!

Edit: Got with the group and they suggested that I learned the brown note instead of dubstep bass. I went with it and came to the conclusion that my bard, after learning the spot on his drum to cause the note, I tried emulating the Brown note with my vocal chords and ruined my vocal chords. In a musical piece where you played both the brown note and sang it would contact you to beings of not this world: The Great Old One from the warlock pact. I chose Dendar, the night serpent as the campaign has 7 evil followers known as the seven serpents and the leader is Medusa. Also bards are known to have a way with words.

TLDR;Bard found the Brown Note
