How do you learn the modal systems and the method of tuning the instrument?

(a proper download link to the English version will be provided soon)

チューナー?採譜?ないほうが、もっと上手く唄えるし、弾けるんだ!

(the Japanese version is in progress)
You are advised to go through this document carefully, by applying each step on the instrument. When having reached the end of the document, you will have a deep understanding about how both traditional music and an instrument like the sanshin work.

Here is a summary of the thoughts which made me write the document:
