how does vinyl work?

I am dumb, please tell me. How do the rings of lines on the record make tunes!? What is happening there?

      "The stylus (needle) rides in a groove that is cut with the same signal/wave that you would see on a scope - the original waveform. The needle/stylus generates a signal between coils (the cartridge)and that signal is passed onto a phono stage for amplification"

      this means nothing to me, You say stop being lazy but this is like a different language.

      • Um, I dunno either

        I was too lazy to look at anything other than the first couple of google results.

        Word.

      • if i paid attention in college i'd be able to give you a better answer but..

        sound is transmitted in waves. that picture on the second website being a good example.
        i'm not terribly sure about this, but it seems as though grooves on a record are just waves cut really really finely.

        "Mono LP's (and cartridges) respond to left/right groove modulations only (2 dimensional groove cutting), stereo uses vertical modulations as well (up/down -- 3d groove cutting)."

        the sound is generated when the needle moves left and right - therefore working out the waveform. that's why the place the needle touches is in line with the arm.
        then these modulations are converted by the cartridge and amplified.

        does that make sense? i really should listen in college. :(

        • So basically

          "The stylus (needle) rides in a groove that is cut with the same signal/wave that you would see on a scope - the original waveform. The needle/stylus generates a signal between coils (the cartridge)and that signal is passed onto a phono stage for amplification"

          • this is why

            when you play vinyl, if you turn the sound down you can still hear the music. it also explains why this works:

    I went to a record cutting studio once- really interesting watching the groove being cut.

    My name is engraved in the runout groove of the first side of The Futureheads lp, which is what was done when I was there
