The first option is to use something like an EL Wire Sound Kit. These are sold online from various places and include some combination of electroluminescent wire, a power adapter, and a special power inverter that drives the wire’s power in response to sound picked up by an integrated microphone.

The whole kit typically costs around $50. You can get the EL wire in different lengths, colors, and thickness. You can use splitter cables to drive multiple strands of wire. It’s a great, uncomplicated solution, but it does have some drawbacks.
