Phonography is the use of a phonograph, also known as a record player. If that's something that turns you on, then you might want to speak with a licensed counselor...or at least a freelance DJ. If you're just interested in how it works, that's much less dangerous than
other things you could be watching.
While most people would attempt to
listen to phonography, it's also possible that a person might want to
watch phonography. So far as we know, the only way to see sounds is to put instant coffee in an energy drink and stir with a tab of LSD. That, of course, is not something we can recommend—either morally or medically.
