Definition and difference between natural semitones and variable semitones

It is a semitone composed of two tones adjacent to each other, or a whole tone is a natural whole tone semitone of the same scale.

Or separate a scale to form a whole tone.

Semitones are variations of whole tones. The white construction of the piano is the natural scale. Mi-fa stands for natural semitone. si-dol stands for natural semitone. dol-re is a natural whole tone change scale. dol-sharp dol is a variation semitone.

Just remember two sentences. 1. The semitone composed of adjacent sounds is a natural semitone, e.g. 1-b2 because 12 is adjacent.

It is a natural semitone 2, and a semitone that is the same or separated by one is a variant semitone. Example, 1-1 They are the same, that is, they are changing. Or 1-bb3 separated by a 2, that is, a change semitone

Natural semitones and variant semitones are the same in terms of acoustics and physics.

The difference is natural semitones: the names are adjacent to c d e f g a b, and if these names are adjacent, e-f is natural, so is c-d.

But the same or separated ones are not. Although the heavy c-flat e is also a semitone, the tonality has changed, and it is impossible to see what the key is. So it's a variation semitone. So there you have it.

A semitone or whole tone consisting of two adjacent levels is called a natural semitone.

Chromatic or diatonic composed of the same and separated scales is called a transchromatic semitone.

Hope you understand.

Example: Variation of semitones c-c (same scale) d-bf (separated by one scale) (not adjacent in the order of c d, e f, g a b).

Methods for judging natural and variable semitones:

1. See if it is an adjacent level, at this time, no matter what kind of diacritical marks are added to these two levels, you don't have to care, just look at whether the letters (sound names) of the scale are adjacent.

If it is an adjacent scale, it must be natural; If it's spaced out, or it's the same scale, it's going to be different.

2. Use the keyboard to find out whether the two tones are full or semitone.

If you are familiar with the keyboard, you can complete the above process in your mind; If you are not familiar with the keyboard, you can draw several sets of keyboards on the draft.

In the music sequence, the minimum distance between two adjacent notes is called a semitone, and the two chromatic distances form a whole tone.

Modern** uses the seven letters c d e f g a b (or its lowercase) to mark sound names.

The pitch distance between the adjacent tones of these seven different high and low tones is divided into semitone and whole tone, where the relationship between e and f and b and c is semitone, and the relationship between the other adjacent sounds is whole tone.

Distinction between natural semitones and variable semitones:

1. The concept is different.

Natural semitone: A semitone composed of two adjacent elementary scales or two adjacent elementary scales is called a "natural semitone", and the composition of a natural semitone can be two basic scales, or two variations, or one fundamental scale and one variation.

Variant semitone: A whole tone consisting of two different forms of the same scale or separated by a scale (two non-adjacent scales) is called a "variant semitone", and a variant semitone can be composed of a basic and a variant scale, or it can be composed of two variations, but it cannot be composed of two fundamental scales.

2. The tonality is different.

A natural semitone is a minor second, and a variable semitone is an increase of one degree or a decrease of a third.

1. Natural semitone: The semitone composed of two adjacent basic scales and the variation of these two basic scales is called a natural semitone.

Therefore, there are three kinds of natural semitones:

First: a semitone made up of two adjacent cardinal scales. There are only two of these natural semitones in each octave – e-f and b-c.

The second type consists of a variation of a fundamental scale and a fundamental scale adjacent to that fundamental scale. For example, there is no c-d-d-down, f-g.

The third type: a semitone consisting of two adjacent elementary scales of variation. For example, B - C, C, C, D.

To sum up, you will find that the two letters that make up the two sounds of a natural semitone must be two adjacent sound names.

2. Variable semitones: Semitones other than natural semitones are called variable semitones.

Therefore, there are two kinds of variant semitones:

The first type of chanting: a semitone consisting of a basic scale and a variation of that basic scale. For example, c-l-c, f-f. The two letters of the two tones in this variation semitone are the same.

The second state stimulus: a semitone consisting of a fundamental scale and a variation of a fundamental scale that is not adjacent to that fundamental scale. For example, D - Drop F, Rise A - Drop D. The two letters of the two tones in this variation semitone are two notals that are not adjacent to each other.

First, the composition is different:

Two tones of two natures adjacent to each other constitute a semitone or whole tone is a natural whole tone semitone of the same scale.

Or separate a scale to form a whole tone.

Second, the meaning is different:

Semitones are variations of whole tones. The white construction of the piano is the natural scale.

Natural semitones and variable semitones, the distance between two tones in height, is called an interval.

Three, the expression of different let cover:

A semitone is the distance at which the interval is smallest and is usually used to calculate the magnitude of the interval content.

Mi-fa stands for natural semitone. si-dol stands for natural semitone. dol-re is a natural whole tone change scale. dol-sharp dol is a variation semitone.

Introduction to the vertical pass of the silver slippery.

In the musical sequence of the musical system, the minimum distance between two adjacent notes is called a semitone, and the distance between the two chromatic tones constitutes a whole tone.

Modern** uses the seven letters c d e f g a b (or its lowercase) to mark sound names.

The pitch distance between the adjacent tones of these seven different pitches is divided into semitone and whole tone, where the relationship between e and f and b and c is semitone, and the relationship between the adjacent sounds is the whole tone.

1.Variation semitones:

It is a semitone consisting of two pure fundamental scale variations of the same or non-adjacent one, which can be composed of one basic scale and one variation, or two variation scales.

2.Variation of the whole tone:

A whole tone consisting of two different forms of the same scale, or two tones separated by a scale, is called a variation whole tone.

3.Natural semitones:

A semitone made up of two adjacent levels is called a natural semitone.

4.Natural Whole Tone:

A whole tone (substance) consisting of two adjacent (outwardly expressed as adjacent names), or a variation of these two (adjacent) basic scales, is called a "natural whole tone".

A natural semitone is a semitone consisting of two adjacent cardinal scales and variations of these two cardinal scales. There are three types of natural chromats:

1.A semitone made up of two adjacent cardinal scales, this natural semitone has only two in each octave – e-f and b-c.

2.A semitone consisting of a variation of a fundamental scale and a fundamental scale adjacent to that fundamental scale, such as So, e.g. c-flat d, f-sharp.

3.A semitone consisting of two adjacent fundamental scales, e.g. b-c-c-d-d-apr.

There are only two pairs of natural semitones, the 3 and 4 on the white key and the 7 and 1 groups, and the others are all variable semitones.

In the case of a piano, for example, all the white keys and the adjacent black keys make up a variational semitone.

A whole tone is the sum of two semitones.

Semitone, whole tone refers to the pitch and has nothing to do with the name of the tone.

The semitone and whole tone of the name are the difference between natural and varied from the name.

With or without a rising or falling sign, the semitones and whole tones of adjacent names are natural semitones, natural whole tones;

Semitones and whole tones of the same or separated names are variant semitones, variation whole tones.

It is best to understand it better with a few examples.

For example, d and be are natural semitones, and d and d or bbf are variant semitones. Although be, d and bbf are the same sound in the twelve equal temperaments.

Natural Semitone A semitone formed by two adjacent cardinal scales and their variations.

Variant Semitone A semitone formed by the same cardinal scale or two non-adjacent cardinal scale variations.
