Stay away from Conan

"With this doubt in mind, I tried to find a way to visit the only music teacher on the island, who was Keiji Aso's first piano teacher. As the only music teacher on the island, since Keiji Aso and Kameyama are the four Childhood friends, so obviously, their music lessons were all taught by the same teacher, and from that music teacher, I learned one thing—"

Minding his own business, Gao Yuan continued:

"That is, because the teaching resources on the island are scarce, the teacher has never taught musical notation. If Keiji Aso had not shown good musical attainments at that time, he was recommended by this teacher to go to a school in Tokyo. , otherwise people born on this island can basically only understand simplified musical notation——

"Therefore, I couldn't help but think of a possibility, that is, when Aso Keiji secretly communicated with Kameyama and others, the secret codes used were actually written in abbreviated notation. In this way, the music score Aso Keiji finally left in five-line notation was actually written by them. The four people couldn't understand it at all, thus giving the score a chance to be preserved.

"However, although this result makes sense, after careful consideration, I still rejected this possibility——

"If Kameyama and others already know that musical notation can be a code to convey information, then whether it is written in abbreviated form or five-line notation, Kameyama and others will notice something strange. Moreover, it is not difficult to understand the five-line notation. Just find someone who understands music theory to convert the music notation into simplified notation.

"Therefore, after I rejected this conjecture, and since I already know that Kameyama and others may not understand musical notation at all, it can be deduced from this that it is possible that they do not need to understand it at all?

"After all, taking the opportunity of overseas performances to smuggle illegal drugs, and then transporting them back to the country through the hidden opening of the piano... Now that the entire smuggling route and process have been clearly regulated, then the relationship between Keiji Aso and the four people is really Is it necessary to leave room for communication using secret codes?”
