Isn t it the same to increase by four degrees and decrease by five?

It can't be called minus fifth.

The 1-sharp 4 and 1-flat 5 intervals have the same number of notes, but the degrees are different, the former is a fourth interval and the latter is a fifth interval. Therefore, 1-liter 4 can only be called an increase of four degrees, and 1-descending 5 can only be called a decrease of five degrees, which cannot be confused.

If you play the fourth and the fifth in isolation, the sound is exactly the same.

In other words, the difference between increasing the fourth degree and subtracting the fifth degree is that the degree is different. It is recommended that you take a good look at the book to figure out what is called a number of tones and what is a degree.

In addition, the intervals I discuss here are all up single intervals by default, and I will not consider the downward and polyphonic intervals here. Actually, of course, I don't think about it because I know you're asking this question with an uplink monotone!

That's right, the black key between 4 and 5 on the piano can be called either a sharp 4 or a flat 5.

A pair of tones like 4 sharp and flat 5 in the same position on the piano keyboard is called equal tone in music theory.

Although the position of the isophony is the same, the name is different and the meaning is different. A rise of 4 means that 4 raises a semitone, while a flat of 5 means that 5 decreases a semitone, which means that the process of getting that pair of equal tones is different.

So, when that key is called flat 4, 1-flat 4 is a fourth, and when that key is called flat 5, 1-flat 5 is a fifth interval.

A pair of intervals that are in the same position on the piano keyboard, such as an increase of a fourth or a decrease of a fifth, is called an equal interval in music theory.

I still recommend that you learn the relevant knowledge of intervals, otherwise you will not be able to fully understand the problem unless it is unexpected. The two concepts of intervals and degrees must be understood.

The difference of one degree is very important.

The fourth and fifth degrees can be the same???

They are only one degree apart, not to be confused, and the acoustics are the same, but the degrees are different.

In the interval, the fifth is a pure fifth, the increase of the fifth and the decrease of the fifth, the 1 5 is the pure fifth, the addition of a plus is an increase of fifth, the subtraction of a b is a decrease of fifth, like the doubling of a fifth is a b1 5 times the reduction of a fifth is 1 b5.

There are no major fifths or minor fifths for fifths. Pure fifths are like 15, 26, 37, 41, 52, 63;Increase the fifth degree 74. The presence of diacritical marks does not necessarily mean a change of interval, for example, 7 and 4 are pure fifths.

Diacritics can change one interval into another.

Number of pitches. Speaking of intervals below, the magnitude of intervals is measured in degrees. The most basic intervals are pure one degree and pure octaves. A pure degree is two tones of the same kind, and there is no distance called a pure degree.

The reason why the pure octave is basic, as mentioned above, will not be described, and in many cases, the attributes of the pure octave are similar or even the same as the pure octave. On top of these two intervals, plus two intervals of pure fourth and pure fifth, these are the four basic pure intervals.

One degree, octave, fourth degree, five degrees only pure, increase, decrease, multiply, decrease, there is no big or small.

The second, third, sixth, and seventh degrees have greatness, smallness, increase, decrease, multiplication, and decrease, and there is no purity.

What exactly it is depends on how many semitones are between the two tones. Take 5 degrees as an example, a 5th relationship with a difference of 7 semitones is called a pure fifth, a 5th relationship with 6 semitones is called a reduced fifth, and a 5th relationship with 8 semitones is called an increased fifth.

Subtract five 7-4, the others are pure five, and increase five is the characteristic interval of harmony and majority.

There is no big five, small five, only pure five, increase five, subtract five.

1. Pure fourth: A fourth that contains 2 whole tones and 1 semitone is a pure fourth.

For example: c f; d–g。

2. Minus fifth: A fifth that contains 3 whole tones is a minus fifth.

For example: b f.

3. Do-Fa is pure four, and Fa-Si is increased four. The use of the fourth degree in music theory is relatively rare, and the so-called concept of increasing and decreasing the size is the translation of the European ** system, in this system, the main thing to look at is the third degree, followed by the fifth degree, and then the seventh degree, and the use of the fourth and sixth degrees is often a reflection, and after the restoration, it is still to see the third degree and the fifth degree. The third determines the feeling of the chord, the fifth of the voicing hand perfects the chord, and the seventh is the sensitive tone, and these determine the general feeling of the chord.

Pure fourths, minus fifths, practised fourths, and pure fifths are common intervals in **theory, and they indicate the difference in pitch between two notes. Here are the specific differences between them:

1.Perfect fourth: A perfect fourth is defined as a pitch difference of 5 semitones between two notes.

For example, counting five semitones up from the C note will reach the G tone, which is a pure fourth. A pure fourth is generally considered to be a more stable and harmonious interval.

2.Diminished Fifth: Diminished fifth is when the pitch difference between two notes is 6 semitones.

For example, counting 6 semitones up from the C note to the GB (or F) sound is reached, which is a minus fifth. Reduced fifths are also known as "devil intervals" or "devil intervals" because it is considered to be an unstable and dissonant interval in traditional theories.

3.Augmented fourth: An augmented fourth is when the pitch difference between two notes is 6 semitones.

The increasing fourth and the decreasing fifth are actually the same interval, just in a different way. For example, counting six semitones up from the C note will reach the F (or GB) sound, which is an increasing fourth.

4.Perfect fifth: A perfect fifth is defined as a pitch difference of 7 semitones between two notes.

For example, counting 7 semitones up from the C note will reach the G tone, which is a pure fifth. Pure fifths are also considered to be a more stable and harmonious interval, and it is often used in **.

To sum up, pure fourths, minus fifths, increasing fourths, and pure fifths differ in pitch differences, with pure fourths and pure fifths considered stable and harmonious intervals, while minus fifths are considered unstable and dissonant intervals, and increasing fourths and minus fifths are actually the same interval, but with different nomenclatures.

Increase the fifth degree to solve the forest to the fifth degree.

1 to 5 liters are increased fifths.

Increasing the fifth interval is to add one semitone on the basis of the pure fifth, and the pure fifth contains seven semitones, so the increase in the fifth contains eight semitones, and the number of tones is 4.

In the range from 1 to 5, it contains five steps.

1234 liter 5) and has eight semitones, of which: 1 to 2 is a whole tone, 2 to 3 is a whole tone, 3 to 4 is a semitone, 4 to 5 is a whole tone plus a semitone (the number of tones is 1 and 1/2), a total of eight semitones are carried by a number of 4. Conforms to an increased fifth.

Add five information:

The distance is an interval of five tones, denoted by the number 5. Explanation of pure fifth nouns: The five steps contain three semi-whole intervals, which are represented by pure 5; Explanation of the noun of increasing fifths:

The five steps contain four whole intervals, which are represented by an increase of 5; Explanation of the noun minus fifth: the interval between the five levels contains three whole tones, which is represented by minus 5; Compare three diatones.

In addition to pure fifths, subtracted fifths, and increased fifths, there are also multiplier fifths and multiplier fifths. Intervals with a number of 2 and 5 degrees are called decremented fifths, e.g. c-flat g. An interval with a number of 3 and a degree of 5 is called a reduced fifth, e.g. c-flat g.

Explanation of the noun of the multiplication-subtracted fifth: The interval between the five levels contains two semi-diatonic intervals, which are represented by a subtractive five.

The number of notes for increasing fourths and decreasing fifths is the same because they mean the same thing.

Although they are close to the concordant interval, they are not consonant intervals. They are all 6 semitones, but a degree of 4 is an increase of four, and a degree of 5 is a decrease of five! Look again, 5 semitones in a pure fourth, 7 semitones in a pure fifth, ah, they are really close to the consonant interval!

Summary. An increasing fourth is an interval that is one minor second less than a pure fifth.

An increasing fourth is an interval that is one minor second less than a pure fifth.

For example: 4 (Fa) to 7 (Si), or 1 (Do) to 4 (Fa); The reduction of the return or stool fifth is the interval of one less than the pure five regimental auspiciousness. For example, bass 7 (si) to 4 (fa), or 1 (do) to 5 flat (so).

Extended information: Pure four and pure five are perfectly consonant intervals, which are auditory manifestations of Qi Meng's pure and impurity-free effect; The increase of four is the structural form of more semitones than the pure four, and the subtraction of five is the form of the formation of the group with fewer semitones than the pure five, both of which belong to extremely dissonant intervals. You first listen to the pure four and pure five of the harmonic interval to establish the concept of harmony, and then it is easy to add four and subtract five as soon as you listen to it.

In addition, all interval learning must have a singing link, that is, to use any key pitch on the piano to go up and down to try to sing the pitch distance of each interval from the second, third, fourth, fifth to octave. Finally, I wish you good luck in your studies!
