Could music ever be electromagnetically broadcasted as visible radiation?

I know that music on the radio is broadcasted through radio waves and then reinterpreted through a device to emit the specific code of sounds. But, do we have the technology to build a broadcasting antennae that has the ability to emit music at a short enough wavelength in the visible spectrum, that we would visually be seeing music? Sorry, for the run-on sentences.

I think you are not asking if this would be a practical way to transmit music to radios, but rather whether it could be done: whether you could "see" the sound.

The answer is definitely yes, but - oops - really 'no'. In your question you mention how radio waves are 'reinterpreted' into sound. It is important to understand that, essentially - and certainly in modern audio equipment - there is nothing 'fixed' or 'natural' in this reinterpretation. There is sort of equation of relationship, an interactive circuitry - and that equation is fulfilled - that circuitry operates - in such a way that you hear sound that corresponds to electromagnetic waves. Ultimately, though, it is as arbitrary as the dots and dashes used to form words - in Morse code - that have symbolic meaning. Nothing in the dots and dashes really corresponds to the concept, except we have decided to make it so.

Now, we can take sound and come up with a dots-and-dashes relationship with color, and build a device that would carry out that relationship. We could then produce a sound organ, or a video display, that had a slightly different color for every possible frequency. But would we be seeing the sound, or our artistic creation based on the sound?

Nope, the visible spectrum is too weak.

Besides anything shorter than the visible spectrum is harmful.

The visible spectrum cannot penetrate walls and everything, unlike radio waves. Also, remember that light rays have to be reflected from something into our eyes before we can see it, so if there is no surface near you, you cannot see it.

This method also uses more electricity and radios have to be positioned somewhere it can receive the light. Other light sources will create a lot of interference, our light, the sun and our computer, even!
Actually it can and is already being done. Fiberoptic cables and lasers conduct lightwaves to transmit encoded sound information. The color of the light does not make too much difference, so if you are looking for a beautiful light show that is somehow integral to the music, that is not how it works.

It works using the principals of fm and digital broadcasting. The lightwaves are so short and move so fast that billions of them can get propogated and interpreted every second. This makes it a great way to send massive amounts of digital info by laser and fiberoptic cables. Thousands of audio streams of the highest qualities can be broadcast simultaneously using these channels.

These are not musical signals sent out through visible multi color antennaes, which I guess would be like big multicolor visible beacons sending out continuos light shows. That actually does sound like fun but could be considered a public nuisance by some folks. Also. how do you get more than one song at a time through the light antennae without creating a mishmosh. But I guess the whole thing would be a bit of a mish mosh anyway. I bet deaf people would really like it.
