Q+A #4: Interval Inversions

The video tutorial explains interval inversions in music theory, demonstrating how to invert an interval by moving the bottom note up an octave. It highlights the relationship between intervals and their inversions, showing that the sum of the interval numbers always equals nine. The tutorial also covers how perfect intervals remain perfect when inverted, while major and minor intervals become their opposites. Examples include inverting a major third to a minor sixth and a perfect fourth to a perfect fifth. The video concludes with a quick summary of these concepts.

What does it mean to invert an interval in music theory?

• To change the key of the interval

• To move the top note down an octave

• To turn the interval upside down by moving the bottom note up an octave

• To double the frequency of the interval

When inverting a major third interval, what does it become?

• A perfect fourth

• A minor third

• A minor sixth

• A major sixth

What is the sum of the interval numbers when an interval is inverted?

• 10

• 7

• 8

• 9

What happens to a perfect interval when it is inverted?

• It remains perfect

• It becomes an augmented interval

• It becomes a diminished interval

• It becomes a minor interval

How does an augmented interval change when inverted?

• It remains augmented

• It becomes a perfect interval

• It becomes a diminished interval

• It becomes a major interval
