A specific interval is the distance between any two notes measured in halfsteps.
A specific interval will be different from the generic interval because the generic interval is the number of lines and spaces, which will not line up with the number of halfsteps.
Specific intervals tell us something abou the quality of the intervals such as if the interval is major, minor, augmented, diminished or perfect.
To measure a specific interval begin with the bottom note and count 1 for the first half step between the bottom note and the next half step up. Proceed by counting up 1 for each half step until you reach the top pitch.
Here is a list of the number of half steps and the specific interval name:
- 1 - minor 2nd
- 2 - major 2nd
- 3 - minor 3rd
- 4 - major - 3rd
- 5 - perfect 4th
- 6 - tritone
- 7 - perfect 5th
- 8 - minor 6th
- 9 - major 6th
- 10 - minor 7th
- 11 - major 7th
- 12 - octave
