Intervals are played one note after the other and chords all at once. Each question moves to a different starting note, so what is being tested is the distance rather than the memory of the last one.
What it is asking about
| Interval | Half steps | What it is |
|---|---|---|
| minor second | 1 | One half step, written as a second: the smallest distance between two notes with different letters. |
| major second | 2 | A whole step. The distance between most neighbouring notes of a major scale. |
| minor third | 3 | Three half steps. The interval that makes a triad minor. |
| major third | 4 | Four half steps. The interval that makes a triad major. |
| perfect fourth | 5 | Five half steps. Turned upside down it becomes a perfect fifth. |
| augmented fourth | 6 | A perfect fourth widened by a half step. Same sound as the diminished fifth, different letter, different behaviour. |
| diminished fifth | 6 | A perfect fifth narrowed by a half step. The interval inside every diminished triad. |
| perfect fifth | 7 | Seven half steps. Stack twelve of them and you land back where you started, give or take a comma. |
| minor sixth | 8 | Eight half steps. The major third turned upside down. |
| major sixth | 9 | Nine half steps. The minor third turned upside down. |
| minor seventh | 10 | Ten half steps. The interval that sits on top of a dominant seventh chord. |
| major seventh | 11 | Eleven half steps: a half step short of the octave, which is why it leans on it. |
