In the next set of lessons, we will review all twelve intervals.
Here is a breakdown of the characteristics of each:
| Interval | Half Steps | Category |
| Minor 2nd | 1 | Strong Dissonance |
| Major 2nd | 2 | Weak Dissonance |
| Minor 3nd | 3 | Imperfect Consonance |
| Major 3rd | 4 | Imperfect Consonance |
| Perfect 4th | 5 | Perfect Consonance |
| Tritone | 6 | Strong Dissonance |
| Perfect 5th | 7 | Perfect Consonance |
| Minor 6th | 8 | Imperfect Consonance |
| Minor 7th | 10 | Weak Dissonance |
| Major 7th | 11 | Strong Dissonance |
| Octave | 12 | Perfect Consonance |
When played as chords, the key is to judge the level of dissonance or roughness of each interval.
Imperfect consonances tend to have an warm, emotional quality.
Weak dissonances tend to be rough but somewhat neutral.
Strong dissonances sound quite harsh.
