    I always thought the mario 64 staircase theme was infinitely ascending

    It’s like a very wonky g chromatic scale with very painful glisses, but as soon as you get to the Bottom g, it goes back up to the top g. Infinite pain. The next thing is an actual decent c chromatic scale, but it still goes on with the *infinite loop of pain*

    if you focus enough you can hear when the loop start again. Pretty cool tho
    Edit: didn't notice the full video, I saw this first

      Ah, but there is no loop :-) It's a synth-generated tone that continues indefinitely. If you are hearing something like "starting again" it's probably due to your playback chain emphasizing certain frequencies.

      @@CaseyConnorOh, really? I watched another video about that same effect, but with a different method (using a loop of notes, not computer generated) and maybe I'm hearing that. Just a bit of overlapping things in my head :P

      @@havidraak2734 Oh, yes, there are indeed new tones coming in, there just isn't a cut-off point where the clip "loops". The new tones fade in, so they aren't supposed to be obvious when they enter, but some playback chains will make them strand out more and that will draw the ear's attention to them. That gets really pronounced if you make the tone descend really fast: it stops sounding like a descending tone and starts sounding like a repeating siren or something, due to the playback chain.

      @@havidraak2734 You can do a looser version of this with a looper and your voice. The trick that I discovered is to first record 1 second loop of silence (really!), then put the looper in overdub and, with the mic as far from your face as possible, start slowly sliding the pitch of your voice up from your lowest note while bringing the mic towards your face so that it gets there about a third of the way up your range, then at 2/3 of the way up, start taking the mic away from your face. Done! Of course, you can do the same, but descending (which is excellent for playing a quick grab of in response to a bad joke).

    The Make Noise tELHARMONIC has a function called "Spiratone" that achieves this exact illusion. This video also reminds me of Jean-Claude Risset's "Mutations" piece.

    I have a cheap music keyboard that does this on its organ sound as you go up/down the scale. IIRC, it was a casio sk-10...

    I tried speeding up the video and a bit easier to hear how the illusion works. Especially around 1:43 at 2x speed

    Prog Rock band Yes achieves this effect to glorious, quasi-religious effect in their song 'And You and I'. Listen to the midsection that begins around 3:40 and lasts until around 5:40. It seems to ascend continually for two whole minutes.

    I'm working on a guitar part that recreates this illusion. Its anchor is 4 chromatic notes on the high E play from high to low. This alternates with a descending pattern that goes down the full chromatic scale.
    It's based on a classical finger excersise.
    Trust me this is worth the pain or reading and working out. It's one of the best finger exercises Ive ever come across
    Start with pinky on the 5th on the high E. 1 finger per fret.
    5th High E
    2nd B
    4th high E
    5th G
    3rd high E
    4th G
    2nd high E
    3rd G
    5th high E
    2nd G
    4th High E
    5th D
    3rd high E
    4th D
    2nd high E
    3rd D
    5th high E
    2nd D
    4th high E
    5th A
    3rd high E
    4th A
    2nd high E
    3rd A
    5th high E
    2nd A
    4th high E
    5th low E
    3rd high E
    4th low E
    2nd high E
    3rd low E
    And repeat.
    That's that pattern I'm messing with to get the illusion.

      Trust me that stretch with your ring finger on the high E and your pinky on the low E is going to hurt if your aren't used to that kind of action

    I have perfect pitch, so I can easily tell when it loops around itself, which means that sadly this trick doesn't really work for me.

    • @CaseyConnor

      There is no loop, per se, so what you are probably hearing is when a new tone comes in? That's not too surprising -- it could be that your ear is very sensitive to a particular frequency, or, more likely, that your playback system favor a certain frequency range so when a new tone comes in it jumps out at you a little bit and catches your attention. As long as the overall effect is that the overall sound is rising or falling forever, the illusion is doing its job.
