Lesson Note 1
Tuning
For the longest time, I couldn't tune the violin by myself, because I thought I do not have perfect pitch so could not tell when they are in tune. However, the?teachers?told me, I can still train my ears and acquire the relative pitch.
I started tuning by playing A and D, and trying to hearing for thegolden sound of the?perfect?5th interval.
But what exactly is the?perfect 5th interval? Here are some descriptions I thought helped me found the golden harmonic?interval.

Don't fight with it, sink into the sound.
-Yuki numata
Listen for that harmonic 'wawawa...' sound..
-Seth Van Embed
Listen to it carefully, your violin will tell you when it is in tune.
-Susan Kim
你慢慢調(diào),是純五度perfect Fifth 的時(shí)候,你就會(huì)如沐春風(fēng)
-aridian?& 王澤宇
Furthermore,
I usedpythonplot to present theperfect 5th intervalsound wave for visualization.


Now I can pretty much tune violin by myself now :) !

I am using A=441Hz.
And there is much debate about the?diatonic?scale and?Pythagorean?scale, I will organize the differences between them next time......
Happy Practicing!
