Pride's love of music lead him to create Gesang.

but of course Gesang wasnt made just to play music for Pride,

Pride uses him to help keep Wrath under control,and also act as caretaker of Pride's children.

although he loves playing music Gesang himself speaks very little often being mistaken for a mute

Gesang is drawn to music, if he comes across a mortal that play music he likes he'll trick them into having a contest, if the mortal wins Gesang will give them a trinket thats suppose to bring good luck ( it doesn't it act like a homing beacon for other demons) and if Gesang wins he consumes the mortal gaining the mortal's talent.

But if Gesang comes across a mortal the plays music he doesn't he will simply tear them apart

Gesang can control sound waves, he can use sound waves to make shields, blow away enemies, vibrate machines to the point where it eithers falls apart or blows up.

He uses his music to hypnotize his enemies and make them do his bidding. if he is near pride,the other sins or Pride's minions, his music can amplify their strength and even heal them and himself.

Gesang which means " to sing "

the idea of this character came to me after listen to Toccata and Fugue also know the every villians theme and Soundwave from animated and prime

and also another go at the sound cannon

the body is based of a cello/violin/pipe organ
