Intervals refer to the distance or interval between two pitches. It is used to describe the pitch relationship between two notes. Intervals can be the distance between two consecutive notes in a scale, or the distance between different scales

Intervals are very important in music because they determine the harmony, melody, and chord structure of the music. By understanding and mastering intervals, musicians can better perform, create, and understand music.

Intervals measure the distance between two notes. When two notes are in the same line or space, their degrees are the same, and the degrees from C to C are the same.

D to D and E to E are also of the same degree

When measuring general intervals, the ascending and descending signs are ignored first, and only the position of the staff is important. C-C #, D-Db, and A # - Ab are still of the same degree.

As the distance between notes on the staff increases, the types of intervals also increase, with C-D, D-E, and E-F all being second intervals.

C-E,D-F,E-G C-E, D-F, E-G are all third intervals. The third intervals are all in the same position on the staff, either on the same line or on a single space.

C-F, D-G, E-A are all fourth intervals.

C-G, D-A, E-B are all fifth intervals.

C-A, D-B, and E-C are all sixth intervals.

C-B, D-C, and E-D are all seventh intervals.

C-C, D-D, and E-E are all octave intervals.
