Why are interval inversions helpful in harmonic analysis?
They help identify descending intervals and their relationships to ascending ones.
How can understanding compound intervals aid in musical analysis?
It helps understand the quality of larger melodic leaps and how they might be used in music.
Identify this interval: ascending C to E.
Major 3rd
Identify this interval: descending A to D.

Major 3rd
What is interval inversion?
Turning an interval upside down by swapping the positions of the two notes.
What is a compound interval?
An interval larger than an octave, expressed in terms of octaves plus a smaller interval.
Define 'number inversion' for intervals.
Subtracting the original interval number from 9 to find the inverted interval number.
How does 'quality inversion' work for intervals?
Major becomes minor, minor becomes major, augmented becomes diminished, diminished becomes augmented, and perfect remains perfect.
What is the purpose of using compound intervals?
To better understand the interval's quality and how it might be used in music, rather than using large numbers.
