Perhaps the intent of the OP was to show the similarity between instrument makers tinkering with different sound generating techniques, and then public acceptance, approval and most important funding having the enterprise flourish, and the process of mutation first, discovering niche later (or variety thereof) evolution scenario. the gist is: --nothing happens in this world without a creative impetus.
BSW there is a big difference to have music generated by a piece of cardboard (a speaker) and the sound of a real Grand.
