At the video's link at the specific time: https://youtu.be/anxHT-a9FHU?t=1012

If I count above 2 intervals, the ditances would be 10 and 8 (C to C)
But according to to a you tuber, it must be a 3rd and 8th? How can that be an 3rd? I really count 10 notes distance.

I checked 10:12, but didn't understand your question.

In the example he was drawing:
C to G = a perfect 5th
A to E = a perfect 5th + an octave

Can you elaborate?

How can the left be an interval of a 3rd and the right one be an interval of an octave...
I thought the right interval of 10 steps.

No worries!

On his example:
F to A = major 3rd + an octave
C to C = an octave

So I guess your question is, why do we consider "major 3rd + an octave" the same thing as a "major 3rd"?

Good question... I don't really know :p

Anyone know?

Have not seen the vid, but as intervals a third and a third + octave are not the same. 3 steps in a diatonic scale do not equal 10. However, as triads, serving harmonic functions, they serve the same function. E.g. If you have a F major triad as tonic, its function won’t change just because you transpose its bass note F down an octave. Will just give your basic triad another color. So different intervals, same harmonical function.

Unless I'm misunderstanding the context, it's about octave equivalence.

I suppose that subject can fill a topic in itself, if looked at from various angles.

yeah it's technically a 10th, but it can be tedious to label compound intervals when looking at these 2 voice moves, since the main concern is differentiating between types of consonances and dissonances. e.g. 3rds and 5ths and 6ths and octaves are *generally* going to be treated the same as 10ths and 12ths and 13ths and (ew) 15ths, as far as basic rules for dealing with parallels or direct motion go.
