It is true that soundtracks can transmit a lot, in fact, I think there are fundamental in all types of audiovisual content, but as far as manga is concerned, it is necessary that the mangaka knows how to convey the emotions correctly, when they manage to do it well I can tell you that no soundtrack is necessary, but few do it.
Thanks for sharing. Greetings!

because that is the power of the drawings in this case applied to mangas that of course will depend on the mangaka or author and if I am not mistaken it is older than the speech as a form of expression, after studying a little more I will leave my opinion just about that because the drawing can express a lot because it is art.... that the Mona Lisa says it 😃/

porque ese es el poder de los dibujos en este caso aplicado a mangas que claro dependerá del mangaka o autor y si no me equivoco es mas antiguo que el habla como forma de expresión, luego de estudiar un poco mas dejare mi opinión justo sobre eso porque el dibujo puede expresar mucho porque es arte.... que lo diga la Mona Lisa 😃/
