Pipe Organ is a predecessor to Portable Keyboard
We don't often think about the history of musical instruments but it can be useful to do so. The "voices" on your Casio or Yamaha portable keyboard have their origin in the "stops" of pipe organs. Here is an 4 minute lecture I found that I like-- and that you would do well to sit through-- Notice that your 61-key portable music and rhythm keyboard does indeed have several digitally-created organ sounds on it. You actually have history built into your instrument!
One of the most famous songs ever played on the pipe organ was composed by J.S. Bach called "Tocatta and Fugue in D minor".
