  • dude...GOT to get that piano tuned. It is futile to demonstrate harmonics when the 3-string unisons for each note are so badly out of tune. it even confused your scope!

  • @cjheaford

    I call it "character." The piano has lots of "character." :)

  • That's obviously a HP 'scope from the looks of it, but which model exactly?

  • @Gameboygenius

    HP 54602A Oscilloscope

  • @DrDaveBilliards I have (access to) a HP 54600A. Would you mind telling me how to access the spectrum analyzer, so I can check if "my" scope has it, the next time I have a chance to play with it.

    BTW, speaking of spectral analysis, check view > spectral view in Audition for a bit of fun.

  • @Gameboygenius

    If I remember right, it's under the "Math" or "Special Functions" menu under "FFT." Maybe you can find a manual online to see if your model supports this (and to find out how to access it).

    Good luck.

  • Man, the E (5 times the original frequency) is badly out of tune.

  • autoscale ftw

  • I wasn't really implying anything. I agree that our vision capabilities are much more powerful than our auditory capabilities. I also agree that the frequency range differences are not really important ... although, still interesting.

  • Well I am trying to work on that sort of thing right now. But what i think is that colours are not the most important part of our vision sense. When you say better, you most likely mean more versatility in encoding/decoding information. Am i wrong? When it comes to information, you can go beyond colours : shadows, textures, patterns, symbols :--> throuhg these our eyes are "better" or just as good as our ears, but not when it comes to single colours, for now at least!
