• In music, the verb invert means to move the lowest note in a group an octave higher.
• In this lesson, we will be inverting intervals.
• For our first example, let's invert a perfect fifth: C to G.
• To invert this interval, move the lowest note (the C) an octave higher.
• The result is a perfect fourth: G to C.
• Next, let's invert a perfect fourth: F# to B.
• Move the lowest note an octave higher.
• The result is a perfect fifth: B to F#
• Perfect intervals will always invert to other perfect intervals.
• Fourths and fifths will invert to each other.
• Let's invert a major third: C to E.
• Move the lowest note an octave higher.
• The result is a minor sixth: E to C.
• Let's invert a minor third: E to G.
• Move the lowest note an octave higher.
• The result is a major sixth: G to E.
• Minor intervals and major intervals invert to each other.
• Thirds and sixths invert to each other.
• Let's invert a major seventh: C to B.
• Move the lowest note an octave higher.
• The result is a minor second: B to C.
• Seconds and sevenths invert to each other.
• Finally, diminished and augmented intervals invert to each other.
• To demonstrate this, let's invert an augmented fourth: C to F#.
• Move the lowest note an octave higher.
• The result is a diminished fifth: F# to C
• Use this chart to quickly invert intervals.
