In the live stream on 4/21/18 a couple things were discussed.
The first thing (after a couple minutes of improv to start the stream) is how you can stop the bending of your guitar string without doing a bend release.
Then, to answer a special request, Happy Birthday was played in both a Major and Minor key.
***I believe at one point in the live stream I incorrectly said that the key of A minor was the relative minor key to A Major. That is WRONG!!! What I meant to say is that the key of A minor is the PARALLEL key to A Major***
This blog entry contains the resources used in putting together the live stream that covered the scales Hirojoshi (sometimes spelled Hirajoshi) and Kumoi.

Hirojoshi (aka: Hirajoshi) Scale Guitar Riffs
Kumoi Guitar Scale Riffs
The Difference Between Kumoi and Hirojoshi
The Kumoi Scale has the following intervals = 1, 2, b3, 5 and 6
The Hirojoshi Scale has the following intervals = 1, 2, b3, 5 and b6
The only difference between these two scales is that the Kumoi has a natural 6, and the Hirojoshi has a flat 6.
People Naming the Scales Incorrectly
If you go by what the Guitar Grimmoire says, and a few websites, the intervals I listed above are correct.
In this video, the Hirojoshi scale is demonstrated, but the teacher calls it the Kumoi scale instead: www.youtube.com/watch?v=eDXOCNq9UH4
Here's that lesson on Guitar World's website: www.guitarworld.com/what-world-kumoi-japanese-scale-tab-and-video
If you look at the comment left at the bottom of the lesson, someone states that the Hirojoshi scale is indeed being used, and not the Kumoi.
Even wikipedia has the Hirajoshi scale listing notes/intervals that are actually the Kumoi scale, according to the Grimmoire.
Oli Herbert of All That Remains does a lesson for Guitar World on the Hirajoshi scale, and uses the same intervals that the Grimmoire does. www.guitarworld.com/lessons/investigating-hirajoshi-scale
Here's another site that has the intervals for Hirojoshi the same as the Grimmoire (although it begins on the 2nd instead of the first): www.pianoscales.org/hirajoshi.html
