### Intervals

Intervals are the distances between any two notes. Each interval will have a number - 1, 2, 3, 4, 5, 6, 7, 8. These numbers are the distance between two notes, based upon counting the lines and spaces on the staff. For example, if we count lines and spaces, starting from C and ending on G, we count: C,D,E,F,G = 1,2,3,4,5, Therefore, the interval from C to G is a fifth (5th).

We can also keep counting past 8, through 9, 10, 11, 12, and 13, but usually not past 13.

List of interval types:
• Unison - 1
• Second - 2nd
• Third - 3rd
• Fourth - 4th
• Fifth - 5th
• Sixth - 6th
• Seventh - 7th
• Octave - 8ve
• Ninth - 9th
• Tenth - 10th
• Eleventh - 11th
• Twelfth - 12th
• Thirteenth - 13th
Interval quality:
Intervals also have another identifier in addition to number called the interval quality. Intervals can be called Major (M), minor (m), Perfect (P), Augmented (A), or diminished (d).

Major Intervals: Minor Intervals: Perfect Intervals: Augmented Intervals: Diminished Intervals: Each interval comprises of a certain number of half-steps. With the aid of a keyboard it is easy to visualize and count the number of half-steps that make up intervals.
List of intervals:
• P1, d2 = 0 half-steps
• m2, A1 = 1 half-step
• M2, d3 = 2 half-steps
• m3, A2 = 3 half-steps
• M3, d4 = 4 half-steps
• P4, A3 = 5 half-steps
• A4, d5 = 6 half-steps
• P5, d6 = 7 half-steps
• m6, A5 = 8 half-steps
• M6, d7 = 9 half-steps
• m7, A6 = 10 half-steps
• M7, d8 = 11 half-steps
• P8, A7 = 12 half-steps
