This ball of sound as it may be known as a distinct appearance of a semibreve. Though there is a hole in the center this seemes to radiate the screech that fills the ears of the target upon striking them. This deals D-rank blunt force damage to the opponent if hit.

Effect: The user releases a high potched screech, From their mouth a blast of sound bursts forth that is 29.5 inches [the standard size of a basketball]. This ball of sound as it may be known as a distinct appearance of a semibreve. Though there is a hole in the center this seemes to radiate the screech that fills the ears of the target upon striking them. The real damage is caused by the severe knockback effect. Being thrown backwards from the power of the sound and potentially striking in to other objects or potentially being forced to skid across the ground of the "Semibreve screech" which can knockback the target the remaining distance of the spells range. [EX. if this hit s a target four meters away that target will be knocked back a meter].

Effect: The user conjures a violin and a bow. Requiring three powerful strokes of the violin, the blue whispy bow turns red, the power of the magic literally turning sound to colour. The user then slashes the now physical sound forward creating a slash of colourful sound that is a meter long, it seems to hold a monotone note, a high F. This slash does D-rank cutting damage.

Com ple ted

My name is Yoshino and I'll be supervising these spells.

Lullabye: Regardless of how you're using it, D-Rank sleep spells are not allowed, even if it is only against NPCs. I'm going to have to ask you to change this.

Note of the Banshee: Keep in mind that this is a D-Rank spell. It is incapable of doing multiple tasks at once. Take away the damage to ears and the knockback ability.

Empowerment Song: State that it's a endurance self-buff in the Type section. Add that the buff is of D-Rank.

Song of Sadness: Add that the debuff is of D-Rank and state in the Type section that it is a strength debuff.

Synesthesia: Add that it deals D-Rank damage.

Upon completion, bump for approval.

There is not a place to see what's allowed and what's not as of the time being.

I understand that but the fact that you're using multiple effects/different types of spells fusing it into one is, again, not capable at lower ranks. Knockbacks are considered Supplementary and adding damage to it would prove to be too strong as of the moment.

If you have any other questions, feel free to ask. If you wish to change up your spells with the information provided above, feel free to do so.

Bump upon completion for approval.

Im not sure what you want me to edit or if it was just to see if i wanted to edit anything XD/

The knockback spell was made solely in to a knockback which states damage will only be taken if the opponents hit in to other objects or along the ground [im assuming environmental damages are taken in to concideration IC] so hopefully this should be good to go
