What anime character should I draw say 1 pls

You should draw Eren Jeager from attack on Titan :]

Sora from Kingdom Hearts (I dunno if me counts as an anime character tho)

If not, Tanjiro from Demon Slayer

I hope this helps :)

It depends on what type of third separates the three notes.for example: if you have two mayor thirds is an "aumented chord"if you have two minor thirds is an "diminued chord"if you have one mayor first and then one minor is a "mayor chord"and inverted is a "minor chord"
