Q

Diminished or augmented intervals occur when a….

A

a perfect 4th or 5th interval is raised or lowered by a half step.

20
Q

When a perfect 4th or perfect 5th is lowered by a half step…….

A

it becomes a diminished interval.

21
Q

If perfect intervals are raised by a half step……

A

they become augmented intervals.

22
Q

Diminished and augmented intervals also occur when…….

A

a double flat or double sharp is used.

23
Q

Enharmonic Intervals are…..

A

two intervals, although written differently, will sound exactly the same.

24
Q

Compound Intervals…..

A

When a note is paired up with a pitch that exceeds an octave, a compound interval is formed.

25
Q

When the two notes are flipped….

A

this creates an inverted interval.

26
Q

What is a common formula used for many interval inversion?

A

common formula is to subtract the original number from 9.

27
Q

What is the second step in interval inversion?

A

The second step in the inversion process is to reverse the quality of the interval. For instance, minor will be switched to major, and diminished to augmented. Perfect intervals, however, remain as perfect.
