Interval knowledge

The height relationship between the two sounds is called the interval, and the interval is used as a "degree" to do the unit.

The interval is divided into two types: melody and sound. The sound in the schedule, the low sound is called "root sound", and the high sound is called "crown sound". As follows:

The schedule is described by the combination of degree and tone, and the two are indispensable.

The number of sounds between the two sounds in the schedule contains the number of sounds, which contains a few sounds called "a few degrees of schedule". For example, 1-1, 2-2 is called "once-tone", 1-2, 3-4 is called "secondary schedule", and 1-3, 2-4 is called "three-degree interval".

The number of sounds contained in the two sounds in the tone schedule. The tone is marked with integers, scores, and scores.

The schedule composed of basic sound levels is called the basic schedule. Let's know the intervals in the basic schedule.

Pure once: The once of the sound of 0 is called pure, such as C-C, D-D.

Small second degree: The second degree of the number of sounds is a second degree, such as E-F, B-C.

Senior degree: The second degree with a sound of 1 is called the second degree, such as C-D and D-E.

Small three degrees: Three degrees of sound of 1 and one-half are called small three degrees, such as D-F, E-G.

Three degrees: Three degrees of tone 2 are called junior three degrees, such as C-E and F-A.

Pure four degrees: four degrees of sound of 2 and one-half are called pure four degrees, such as C-F and E-A.

Increasing four degrees: four degrees with a tone of 3 are called four degrees, such as F-B.

Five degrees: Five degrees of tone is five degrees, such as B-F.

Pure five degrees: Five degrees of tone of three and one-half are called pure five degrees, such as C-G and E-B.

Small six degrees: Six degrees with 4 degrees of sound are small six degrees, such as E-C, A-F.

Great Six Degree: Six degrees of six and one-half of the sound are called big six degrees, such as C-A and D-B.

Small seven degrees: Seven degrees with a tone of 5 are called small seven degrees, such as D-C and E-D.

Seven degrees: The seven degrees of the tone of 5 and one-half are called the seven degrees, such as C-B and F-E.

Pure octa degree: Octagonal is called pure octa degree, such as C-C, D-D.

The above examples are from low sounds to high sounds.

Boeing

Boeing is a decorative sound. It is composed of two the same main sounds, adding short auxiliary sounds above or below the main sound. Boeing has two types: Shun Boeing and anti -Boeing. We only talk about common Shunbo. Under normal circumstances, we say that Boeing refers to Shunwu Boeing. Look at the explanation in the figure below:
