The "music box" is the absolute minimum of sound generation hardware, just a digital output connected to a speaker, sending a square wave of variable frequency. You can either extend the design in software to a sigma-delta modulator or add a DAC or a sound chip. Many FPGA development kits have it.
Then you are free to e.g. implement polyphonic instruments.
