Hi Tomo,
I found when you play E9th with 13th tension. Your left thumb does not mute the 6th string.
So, my question is: At that situation, if you mute the 6th string with the left hand middle finger or you control your right hand to not touch the 6th string?
Thanks so much,
LJ
Here is Tomo's reply:
Don't worry!
In this case, it is a very fast move between the 9th and the 13th, so no need to worry about muting!
