This Grub Init Tune will make your computer sound like a Super Mushroom every time you turn it on! This only works for the Grub bootloader - this generally means you need to have Linux (or other Grub-based OS) installed.
Here's the code, which goes in your /etc/default/grub
file:
GRUB_INIT_TUNE="1750 523 1 392 1 523 1 659 1 784 1 1047 1 784 1 415 1 523 1 622 1 831 1 622 1 831 1 1046 1 1244 1 1661 1 1244 1 466 1 587 1 698 1 932 1 1195 1 1397 1 1865 1 1397 1"
Instructions adapted from https://web.archive.org/web/20150115050225/http://www.iavit.org/~john/debian/grub.html:
-
Edit the file /etc/default/grub. At the end there are lines like the following:
# Uncomment to get a beep at grub start
# GRUB_INIT_TUNE="480 440 1"
-
Replace the
# GRUB_INIT_TUNE="480 440 1"
line with the new GRUB_INIT_TUNE line at the top of this document (make sure to remove the "#" from the beginning of the line, as well). Save the file and exit your text editor. Open a terminal window and issue the following command:sudo update-grub
-
Reboot. You should hear the init tune when the grub menu appears.

If you have a desktop computer, you can turn the volume down by physically popping open your system case, finding the PC speaker attached to the motherboard, and applying one or more layers of scotch tape to the speaker. More scotch tape = lower volume. You're welcome!
