A BASIC OVERVIEW OF THE 20 CENTURY CLASSICAL IDEA:
Arnold Schoenberg created a system using all 12 tones in a row. Below is the 12 tone row from OP 25.
The next idea is to use the notes in reverse order. This is called “Retrograde”
We can also take the original tone row and “Invert” it. This is called “Inversion”. We do this by inverting each interval. For instance if a note goes up a perfect 4th in the original set then it is inverted by coming down a perfect 4th, if it goes up a minor 3rd then it comes down a minor 3rd, etc
We can also take the Inversion of the original tone row and play the notes in reverse order. This is called “Retrograde Inversion”
These ideas from 12 tone serialism are excellent for Jazz riffs, Composition and Improvisational ideas and concepts.
