Console BEEP Methods, Notation, and Generation

Introduction

Hark back to the days of text based adventure games, and simple PC, speaker sound.

Background 

In an effort to learn C#, my first project was a text-based adventure game based on "The Hyperion Project" tutorial from XNA Extreme 101 (3D Buzz).  Along the way, I added a considerable amount of code to further enhance the project -- one of which was the addition of sound. 

I found several examples, some of which were quite good -- unfortunately, most were incomplete, contained incorrect frequencies, and/or lacked any examples.

Obviously, the PC Speaker holds very little relevance in this day-and-age -- nevertheless, I hope that this will be useful to someone out there. 

Note Assignment and Frequencies 

The following represents the complete scale -- however, please be aware that many of the lower notes will be extremely quiet and/or completely inaudible. 

In addition, the commented notes fall below the frequency range of the Beep method (which is between 37Hz and 32767Hz).

Sample 

The following is just one of the examples contained in the source code.

Here is my attempt at accurately recreating the Main Theme from the game Space Quest (originally created by Mark Crowe, (C) Sierra Online).
