I know this was intended as a physics demonstration, but it also works remarkably well for music theory in terms of subdividing a beat. I was half expecting the layers to overlap to show different rhythmic syncopation.

This brings back memories. I did basic training in 97, and a few guys were having discussion about harmonic resonance and marching on bridges. Two of the guys were sceptical. I told them we could prove it then and there. We were on the 7th floor of the Mega structure and we had an all steel cage stairway. We started marching in step in the stairs and eventually the sound resonating from the steel bars was unlike anything you can believe. At the bottom on the ground floor the steel handle was moving back and forth and singing an high pitch whine. The duty Sgt almost caught us. We probably could have collapsed the whole stair case had we continued.

just for anyone wondering, N stands for node, A stands for antinode. Nodes mean the points on the strings that appears to stand still, and antinodes are the points on the string that are oscillating with 'maximum amplitude'. + some people have pointed out that the antinodes are points that oscilates with 'maximum amplitude'.You're right. I've added that to the definition. Sorry for the incomplete explanation.

Fun fact, I learned while working on ski lifts that these harmonics are possible on a moving lift line (weather permitting) they often cause lift faults but could be so bad as to actually take out an entire lift line, luckily they now have pneudraulic and hydraulic automatic counterweight systems to relive tension and prevent these

More importantly, the first 6 harmonics played simultaneously are a major triad. Fundemental, octave above, 5th above that, 4th above that, major 3rd above that, minor 3rd above that. Which forms a nice root position major chord.

Perfect demonstration there, thank you for all of this.
As a student in Associate's degree in Electricity this was very satisfying to see Harmonics operate.
After 5th Harmony , I was like he can't do any more. Then it came 6th. That's it, it's the last one. Then I saw 6th, I was like what the hell. Let's keep open mind
I used this set up on paper to explain musical notes and octaves to my students. We derive musical scales from the natural harmonics that come from regular vibrations. We move those divisions up and down octaves to complete the scales. Making the new harmonics from one note into the root of a new scale produces every other note. I think the universe is made of strings and vibrations and energy moving through them. We love music because it is a direct line into the very fibre of our being. I think.

Oh my god, I have been trying to explain this too my kids… this is what I used to do while I was talking on our land line back in the day. I was a kid and would stretch the cord as far as it could go to get privacy and pull back a part of the line like a rubber band and then let it go and watch it wave back and forth at me!

I wasn't able to visualize what harmonic looks like until you showed me this video. So beautiful
The very first demonstration showed a traveling wave (like a wave in a pond) that is reflected at the ends of the rope. That's why it moves forth and back along the rope. The harmonics on the other hand are standing waves since their nodes are in fixed locations. Interestingly any standing wave can be calculated as the sum of two traveling waves that simultaneously travel forth and back. And that is btw. how resonance works.
I used to do this with ropes when I was growing up, I usually spun the rope instead of moving it side to side, trying to see how many I could fit on the rope at a time, its cool to see this as a science demonstration
Love you bro for showing this
It was great that you put nodes and antinodes also for better understanding ❣️
Dude thank you so much, I just couldn't visualize how it would look like before this video
Belíssima demonstração.
Nobody: 8th harmonic:*batman theme starts playing*
At the Austrian mountains, east tyrol, there are heavy thick steel ropes strained over hundreds of meters along the hills slope. At least, I encountered one such rope. If you pull it down fast, strongly and short near one end, the rope seems to not move for up to 10 seconds - then suddenly the wave will come back with full force like magic.
