# Notation - Intervals

Learn to recognize intervals between two notes in four clefs.

### Setup
Clefs Use these checkboxes to select which clefs should be used in the quiz. Qualities Use these checkboxes to select what qualities of intervals should be played. A 'quality' is the same as the 'specific name' mentioned below. Intervals Use these checkboxes to select what intervals should be played. These checkboxes refer to the 'general name' mentioned below.

### Learning the Intervals
Intervals An intervals consists of two parts: a general name and a specific name. The general name is a number, specifically the distance between the two notes (For example, G to A would be a 2nd, and E to B would be a 5th), and the specific name is a quality, as listed below. Note that depending on the general name, some qualities do not apply — for example, there is no such thing as a major 5th or a perfect 3rd. Each quality represents a certain number of half steps to add or subtract from the major or perfect type of each interval.
### Number of Half Steps | ### Quality for 1me, 4th, 5th, and 8ve | ### Quality for 2nd, 3rd, 6th, and 7th
-3 |  | Doubly Diminished
-2 | Doubly Diminished | Diminished
-1 | Diminished | Minor
0 | Perfect | Major
+1 | Augmented | Augmented
+2 | Doubly Augmented | Doubly Augmented
Enharmonic Intervals Note that there can be multiple names for the same number of half steps — for example, an augmented fourth and a diminished fifth are both 6 half steps. While the Aural Skills - Intervals quiz treats these "enharmonic" intervals as being equal, this quiz does not. This is because these intervals are fundamentally different (hence their difference in notation) — not only do they differ in tuning, but they also function in different ways in music. The only reason that the Aural Skills - Intervals quiz treats them as being the same is because it is almost impossible to tell the difference aurally without context.
