Scrib sheet of music theory discussion circa mid nineties

It appears as a conversation upon music theory covered ground that night with a bandmate in a band called ant man bee. The art supplies at our disposal add a colorful chaos to the grand effort towards order as you can see information about the five line staff, subdivision of note duration, even the fibonacci number was touched upon in explain8ng why the keyboard with its two black keys then three (1,2,3,5,8,13) i goofed there with the 12 twelve different notes in a chromatic scale, the 13 would of course contain a repeated note being the octave. Through teaching one starts to stake a claim to the vast concrete scope and depth of music theory.
