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.
What happens to the quality of a perfect interval when inverted?
It remains perfect.
What happens to a major interval when inverted?
It becomes a minor interval.
What happens to an augmented interval when inverted?
It becomes a diminished interval.
Identify this interval: Descending major 3rd
Ascending minor 6th
Identify this interval: F# to B an octave above
Augmented 5th
Identify this interval: G to Db two octaves above
Minor 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.
