In the late 1980's there was an MS-DOS program called PIANOMAN. Yup, in the docs, it's written in all caps like that. This program would let you compose, play, edit, and save tunes, and even compile them into self-contained executables to give to others who didn't have a copy of PIANOMAN themselves. This program's claim to fame was that it could create pseudo-polyphonic music through the monophonic PC speaker by playing different notes extremely rapidly. This was a shareware program (try it for a while, if you like it, send in a registration fee to get the latest version and another disk of sample songs). I just found the shareware distribution of version 4 on Archive.org. One of the included tunes, which exists here only as a compiled, self-contained executable, is a version of a Tom Lehrer classic. Naturally, I figured some folks might be interested in this. It's set up to play repeatedly until a key is pressed, so I've only included three playings in this recording, and the last one fades out. Enjoy! #TomLehrer
