#Interval Inversions and Compound Intervals: Your Night-Before-the-Exam Guide 🚀

Hey there, future music maestro! Let's make sure you're totally solid on interval inversions and compound intervals. This guide is designed to be super clear, quick to review, and exactly what you need to ace that AP Music Theory exam. Let's get started!

#What's an Interval Inversion?

Interval inversion is like taking an interval and turning it upside down. Instead of thinking about ascending intervals only, we consider what happens when we swap the positions of the two notes. Think of it as a musical seesaw! 🎵

Key Concept

Remember, when we talk about intervals, we usually mean ascending intervals. Inversions help us understand descending intervals and their relationship to ascending intervals.

#How to Invert an Interval

Number Inversion: Subtract the original interval number from 9. For example, a 3rd becomes a 6th (9 - 3 = 6), and a 5th becomes a 4th (9 - 5 = 4).
Quality Inversion:
- Major (M) becomes minor (m)
- minor (m) becomes Major (M)
- Augmented (A) becomes diminished (d)
- diminished (d) becomes Augmented (A)
- Perfect (P) remains Perfect (P)

Memory Aid

Think of it like this: Major and minor are opposites, and Augmented and diminished are opposites. Perfect intervals are like the neutral ground, they don't change.

#Visualizing Inversions

Here's a visual to help you see how intervals flip:

Interval Inversions

Caption: Notice how the interval 'flips' when inverted.

#Example: Major Third Inversion

Major Third Inversion

Caption: A Major 3rd (F-A) inverts to a minor 6th (A-F).
