Introduction


Hello all.My name is Dogukan Ozturk. Welcome to my new Music Theory Series Lessons. I know that Andrew has covered all of this subject. But i have decided to do it in my way also user posted image For the first part of the series we will start with the intervals.


Intervals


Intervals are the distances between 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.


Intervals may be described as:
-Vertical or harmonic, if the two notes sound simultaneously.
-Horizontal, linear, or melodic if they sound successively.


Intervals may be roughly classified as:
-Diatonic intervals, between the notes of a diatonic scale
-Chromatic intervals, non-diatonic intervals between the notes of a chromatic scale
-Minute intervals (commas, and microtones), sometimes so small that the difference in pitch between the two notes cannot be perceived.

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

10-Minor Seventh----m7
11-Major Seventh----M7
12-Perfect Octave----P8


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).

  • The intervals contained in the table are diatonic to C major. All other intervals are chromatic to C major.
