Post-Tonal Theory: Base 12 Counting

The video tutorial explains the concept of pitch classes in music theory, highlighting the use of enharmonic equivalency and the fixed do system where pitch Class C is assigned the number 0. It discusses why numbers 0 through 11 are used instead of 1 through 12, emphasizing the mathematical reasoning behind this choice. The tutorial uses a clock face analogy to illustrate how pitch classes repeat in a cycle, similar to how hours repeat on a clock. It concludes with a brief introduction to interval classes, setting the stage for future lessons.

What is the primary reason for using numbers 0 through 11 to represent pitch classes?

• It aligns with the 12 months of the year.

• It simplifies mathematical calculations.

• It is a tradition in classical music.

• It is easier to remember.

How would you describe a chord consisting of pitch classes C, D flat, E flat, and F# using the fixed dose system?

• 1357

• 0247

• 0136
