Why qin music theory? Five modes not pentatonic 五音乃五調 非五聲

Know music theories makes a difference! If you ONLY know one music theory, your music expression is limited. You can write great music, but your expression is limited!! When you try to mimic writing a different language, a native can immediately tell. Be a bilingual or trilingual in music!!!
It will bring your music composition greater potential!!! Understand their terminologies instead of using western frame to contain them. Truly understand a different music tradition.
