The science behind Singing Sand Dunes

grinter says...

>> ^ulysses1904:

Interesting stuff. I assume it's always the same E, F or G frequency just below concert A (440 hz)? or the next octave lower?
I wonder why no F#, or did he leave it out for the sake of brevity. I'll have to read more on this.


If you look closely at the spectrum they show, the energy is just below 100 Hz. So, the G they are referring to is 98 Hz. ..and yeah, it would be continuously variable, so F# is possible.

How to Solve a Song with Math

A. Octave B. 5th C. Tritone

Whenever you hear a pitch, there are also a number of much softer, sympathetic pitches that sound. These are called overtones. (Here is a graphic of the overtone series: http://www.deandrummond.com/oton1.jpg) Overtones are very soft, and usually only the first few are (barely) detectable to the ear - although factors like instrument construction, peculiarities of the performance space and other notes sounding at the same time can affect the production of overtones. The first two in the overtone series are an octave and a 5th, so when ^ Karen Cheng plays the octave and the 5th, the overtone series is reinforcing those pitches, which gives those intervals a very 'pure' sound.

The tritone is the 10th overtone in the series, and occurs 3 and 1/2 octaves above it's root pitch, which means that it is not only very soft, but more often than not, out of the range of human hearing. Although a naked tritone is odd sounding by itself, it is used to create many beautiful, lush and complicated harmonies. Hundreds of years ago, the tritone was considered the interval of the devil by the church and it's use was forbidden. That quickly faded away as western music began to come into its own as an art form. Bach, Beethoven, Mozart, and almost every other notable western composer have used the tritone often in various harmonic contexts.

The oft used chord progression she uses at the end is I V vi IV, which is similar to the Pachabel cannon progression used in a similar video (I V vi iii IV I IV V).

Nice song I guess. She may be a great trumpeter, but this song doesn't demonstrate anything beyond good looks and a full sound. The range of this song was confined to an octave... Beginners could play this.

She would have to play not only at half speed, but at a lower octave, wouldn't she? So that when she sped it up, it would play at the correct octave? Otherwise wouldn't it be very high pitched?

If she played on an acoustic piano, that would shut them up for sure.

Laughing Gas is funny.... very funny

This video is a lie.
I've done Nitrous hundreds of times (even have a $85 personal dispenser) and it definitely does not work that way.
Also, it effects your voice opposite of what helium does - makes it drop about 1 or 2 octaves. None of their laughs seem to be effected by the gas whatsoever. This is something you have no control over. If you inhale the gas, your voice drops.
Last, inhaling/exhaling the way they are doing would be sure to make them seriously dizzy, probably fall over, and maybe even pass out. But again, noone seems to be that effected by it. So, again, I call lie.


Not necessarily if they're nose breathing at the same time. They're obviously not toking on x-times-exhaled air for 30 seconds, so i assume that is a given. Try getting an inflated balloon and breathing in and out (with your nose blocked) 20-30 times, you'd be surprised how hard it is. I'm 99% certain these guys are substituting fresh air with their noses to go with the balloon gas (whatever it is) which they are trying to get the effects of.

This also effects your first statement - if they are breathing in/out to get themselves 'nitro-genated' (like oxygenated but with nitrous, get it?), getting it into their system as best they can - like divers do - breath in and out deeply many times before taking a large breath to get their blood oxygenated due to it soon being highly de-oxygenated, then their lungs wouldn't be full of gas and hence their voices would, at least from a physics point of view, not be affected. The change in octave of taking in certain gases is caused because of the different properties of the gas passing over your vocal chords. Air passing over our vocal chords sound normal to us, heavier gases sound deeper, lighter gases sound higher. So unless the nitrous affects the inner workings of the body such that the vocal chords are slack/tight, the pitch may be unaffected or mostly so.

As for the laughing, i know nothing. I was skeptical of the first guy's stupid laugh. Seemed extremely fake to me, but the other 2 didn't seem that way.

Hmm matters not what octave you use.


Yeah, some people just can't reach the higher or lower octaves needed to sing it like in the original, this is the easy way to help with that. Few people have the vocal range to sing every song in these games spot on.
