what about coming down and playing the higher note then lower note?
The diagrams are broken on this section, I do not see it on my side.
Hi @miichaelp
Conventionally intervals are counted from the lower up to the higher pitched note.
That is not to say they can not be counted down in pitch - they can be and are.
But for most purposes, especially when learning, up is the direction used.

Hello @letsgotho and welcome to the community.
What diagrams do you mean please?

I think there’s supposed to be a guitar chart here like there was for the video before this for the Perfect Fifth Interval, but it’s replaced by xx’s on my screen.
Thanks @letsgotho I see now, and I will report it to add to the ‘fix list’.
@Fanny_JustinGuitar_Team … email sent.

Just wondered if there was any news when the missing diagrams will be added.

while practicing this I was able to figure out the riff from Otherside!! This will be my reference for the Perfect 4th, I figured other RHCP fans would find that useful!
Yet to fix as April 2023
