Musical mode- Another concept from musical theory, which we will get acquainted with. Lad in music- this is a system of relations of stable and unstable sounds and consonances, which works for a certain sound effect.
There are quite a few frets in music, now we will consider only the two most common (in European music) - major and minor. You have already heard these names, you have also heard their banal interpretations such as major - a cheerful, life-affirming and joyful way, and minor - sad, elegiac, soft.
These are only approximate characteristics, but by no means labels - music in each of the musical modes can express any feelings: for example, tragedy in major or some kind of bright feelings in minor (see, it's the other way around).
Major and minor - the main modes in music
So, let's analyze the major and minor modes. The concept of mode is closely related to scales. The scales of major and minor consist of seven musical steps (that is, notes) plus the last, eighth step repeats the first.
The difference between major and minor lies precisely in the relationship between the steps of their scales. These steps are separated from one another by a distance of either a whole tone or a semitone. In major, these relationships will be as follows: tone-tone semitone tone-tone-tone semitone(easy to remember - 2 tones semitone 3 tones semitone), in minor - tone semitone tone-tone semitone tone-tone(tone semitone 2 tones semitone 2 tones). Look at the picture again and remember:
Now let's look at both the one and the other musical mode using a specific example. For clarity, let's build the major and minor scales from the note before.
You can see that there is a significant difference in the notation of major and minor. Play these examples on the instruments and you will find the difference in the sound itself. I will allow myself one small digression: if you do not know how tones and semitones are considered, then refer to the materials of these articles: and.
Properties of musical modes
Lad in music exists for a reason, it performs certain functions, and one of these functions is the regulation of the relationship between stable and unstable steps. For major and minor, the stable steps are the first, third and fifth (I, III and V), the unstable ones are the second, fourth, sixth and seventh (II, IV, VI and VII). A melody begins and ends with steady steps, if it is written in a major or minor scale. Unstable sounds always strive for stable sounds.
The first stage is of particular importance - this, it has a name tonic. Stable steps together form tonic triad, this triad is the identifier of the musical mode.
Other musical modes
Major and minor scales in music are not the only variants of scales. In addition to them, there are many other modes that are characteristic of certain musical cultures or artificially created by composers. For example, pentatonic scale- a five-step mode, in which any of its steps can play the role of tonic. The pentatonic scale is extremely widespread in China and Japan.
Let's summarize. We gave a definition of the concept, learned the structure of the scales of major and minor modes, divided the steps of the scales into stable and unstable.
Did you remember that tonic is main stage of the musical scale, the main sustained sound? Great! Well done, now you can have some fun. Check out this cartoon joke.
There is a wide variety in music frets. By ear, it is easy to distinguish Russian ditties from Georgian songs, oriental music from western, etc. Such a difference in melodies, their moods, is due to the mode used. The major and minor modes are the most widely used. In this chapter, we will look at the major scale.
major scale
Lad, whose stable sounds form a major triad, is called major. Let's explain right away. A triad is already a chord, we will talk about it a little later, but for now, by a triad we mean 3 sounds, taken either simultaneously or sequentially. A major triad is formed by sounds, the intervals between which are thirds. Between the lower sound and the middle one is a major third (2 tones); between the middle and upper sounds - a small third (1.5 tones). Major triad example:
Figure 1. Major triad
A major triad with a tonic at its base is called a tonic triad.
The major scale consists of seven sounds, which represent a certain sequence major and minor seconds. Let us designate the major second as “b.2”, and the minor second as “m.2”. Then the major scale can be represented as follows: b.2, b.2, m.2, b.2, b.2, b.2, m.2. A sequence of sounds with such an arrangement of steps is called a natural major scale, and a mode is called a natural major. Generally speaking, the scale is called the ordered arrangement of the sounds of the mode in height (from tonic to tonic). The sounds that make up the scale are called steps. Scale steps are indicated by Roman numerals. Do not confuse with scale steps - they have no designations. The figure below shows the numbered steps of the major scale.
Figure 2. Major scale steps
The steps have not only a digital designation, but also an independent naming:
Stage I: tonic (T);
Stage II: descending introductory sound;
Stage III: mediant (middle);
Stage IV: subdominant (S);
Stage V: dominant (D);
Stage VI: submediant (lower mediant);
Stage VII: rising introductory sound.
Stages I, IV and V are called the main stages. The rest of the steps are secondary. Introductory sounds gravitate towards the tonic (strive for resolution).
Steps I, III and V are stable, they form a tonic triad.
Briefly about the main
So, the major mode is the mode, in which the sequence of sounds forms the following sequence: b.2, b.2, m.2, b.2, b.2, b.2, m.2. Let us recall once again: b.2 - a major second, represents a whole tone: m.2 - a minor second, represents a semitone. The sequence of sounds of a major scale is shown in the figure:
Figure 3. Natural major scale intervals
The figure indicates:
- b.2 - major second (whole tone);
- m.2 - small second (semitone);
- 1 indicates a whole tone. Perhaps this makes the diagram easier to read;
- 0.5 is a semitone.
Results
We got acquainted with the concept of “mode”, analyzed the major mode in detail. Of all the names of the steps, we will most often use the main ones, so their names and locations must be remembered.
A minor scale (or simply minor) is a seven-step scale, stable sounds of which form a small (minor) triad.
The very word "minor" (it. - minore) in literal translation means "smaller". This term is used in syllabic notation, while in alphabetic notation the word "minor" is replaced by the word moll (from Latin molle, literally - "soft").
The main characteristic feature of the minor mode is the interval of a minor third (m. 3) between steps I and III, which, in fact, determines the specifics, that is, the minority of the joint sound, both the stable sounds themselves and the mode as a whole, in any order of execution of its steps .
In principle, the properties and names of the steps of the mode in the minor will be the same as in the major, only - in some cases - the interval relationships between them and, accordingly, the nature of their sound will change.
The minor mode (like the major one) has three main types: natural, harmonic and melodic minor.
The minor mode is built as follows: tone-semitone-tone-tone-semitone-tone-tone.
Key
The height level of the location of the fret, determined by the sound of the tonic, is called tonality. Placing a fret on the same sounds, but in a different octave, has no effect on the definition of tonality, since neither the structure of the fret itself, nor the names of its steps and their properties change from this.
The name of any key is determined by the name of the sound of the tonic itself (I degree of the mode), but since the key is always inextricably linked with any particular mode (major or minor), an indication of the modal inclination is usually added to its name. Thus, the full name of the key, as a rule, contains two components: 1) the name of the tonic and 2) the name of the mode, regardless of which notation system - syllabic or alphabetic - is used in this case: C major (C-dur), in A minor (a-moll).
The names of major keys according to the letter system are written with uppercase (capital) letters, and minor ones - with lowercase (small). Sometimes, for brevity, the words dur or moll are omitted in the letter system, and then the spelling of the first letter (uppercase or lowercase) indicates the modal mood.
Parallel and eponymous keys of major and minor
Although historically both the main seven-step modes - both major and minor - developed completely independently, without losing their main specific features, there is still a certain relationship between them: the same number of steps, their similar functional significance, the same directions of modal gravity and etc. Scales of some similar varieties of both modes (for example, harmonic major and harmonic minor, or melodic major and natural minor and, conversely, natural major and melodic minor), built from the same sound, will sound almost the same, differing only in the sound of the third degree - the main and only accurate sign of a particular mode.
In music, there are two musical modes that are basic - these are major and minor. Let's talk in more detail about what a major is, what a major mode is and how the major mode differs from the minor mode, as well as how this word is used in modern slang.
What is major: definition
Major is a set of sounds of a musical instrument, implying a peppy and cheerful tone. This wording is due to the fact that all music is inherently created to convey the feelings and emotions of a person. A composer who composes a certain musical composition or symphony is based on his feelings and puts them into music.
The process of developing a musical composition is quite complex and often intertwined with the experimental method of selecting the necessary sounds. Each recorded note is followed by a heavy selection of subsequent notes and an attempt to harmonize them with each other so that the music sounds pleasing to the human ear.
major scale
Due to the fact that the set of sounds is unlimited, and the human ear is able to perceive sounds in the range from 20 to 20,000 Hz, it became necessary to classify certain simple sets of keys. The main ones that can be played on any musical instrument are the major and minor modes. It turns out that the major scale is the sequence of any composition, which, on a psychological level, evokes in a person associations with a cheerful and cheerful mood. Also, any composition can be recorded in a minor key to get the opposite effect of sound and perception on a psychological level. A minor mode is a mode whose sounds form a small and minor triad.
Differences between major and minor
Any set of notes can be written as a major or minor scale. That is, any musical composition consisting of a certain set of notes can be played both in a minor sound and in a major one.
The difference between the major and the minor is that between the second tone and the first in the minor there is a small third, and in the major - a large one. In simple terms, major-minor is a harmonic expression of the states of the soul joy-sadness.
Music term in everyday life
In youth slang, the word major is used in a context indicating wealthy people living in abundance and abundance. It is believed that people with great material wealth get almost everything they want. And the person who gets what he wants is in joy and euphoria. And vice versa: people who do not have a large amount of material wealth do not always get what they want and therefore are not always in a state of joy and pleasure.
Lad represents system of relationships between stable and unstable sounds. Mode is the organizing principle for sounds, thanks to which they are combined into a hierarchical and functionally interconnected system. The scale is also a system of sounds, but unlike the mode, the scale does not determine how the sounds should interact with each other.
The most widespread in music are two modes - major and minor. These modes are made up of seven diatonic steps arranged in such a way that between adjacent steps an interval of a major or minor second is formed. Diatonic can be interpreted as a transition from one step to another.
Example 1. Transition before->re in diatonic is possible, since in this case there is a transition from one neighboring step to another. Transition b-sharp->c-sharp is also possible, since in this case a transition is made between various adjacent altered (increased or reduced) steps. Transition before->C-sharp in diatonic is impossible, since in this case a transition from one level to the same elevated level is carried out. Instead of before->C-sharp in diatonic, the transition should be indicated as before->D flat. Transition b-sharp->d-flat in diatonic is also unacceptable, since this skips a step before, between si And re. Therefore, instead of b-sharp->d-flat correct transition will be b-sharp->c-sharp.
Understanding the following steps in diatonic allows you to correctly build the keys, which will now be discussed. That is, in one key, the first secondary step will be called C-sharp, and in a different tone - D-flat.
The sequence of seconds just determines the inclination of the fret - major or minor.
In the major scale, the seconds are in the following sequence:
b.2, b.2, m.2, b.2, b.2, b.2, m.2
It is very easy to remember this sequence. You can use the phrase "b-b-m-b-b-b-m" or look at the piano keyboard. White keys from one step before to the next step before just form this sequence: do-re-mi-fa-sol-la-si-do. The first four steps of the fret - I-II-III-IV - the lower tetrachord, and the four upper steps - V-VI-VII-VIII - the upper tetrachord. The interval structure of these tetrachords in natural major is identical and equal to b-b-m. The interpretation of the 7-step mode as a sequence of two tetrachords is not used in modern theory (it is considered obsolete), but thanks to them you can see interesting moments. For example, the structure of the lower tetrachord sets the inclination of the mode (major or minor), and the structure of the upper tetrachord determines its type (natural, harmonic or melodic).
The height position of the fret is set tonality. The tonality is set as follows: first the tonic of the mode is called (the first degree of the mode), and then its type, for example: C major .
Rice. 1. Natural C major
The natural minor mode differs from the major one by another sequence of seconds:
b.2, m.2, b.2, b.2, m.2, b.2, b.2
White keys from the step la form a minor scale: la-si-do-re-mi-fa-sol-la.
Rice. 2. Natural A minor
Varieties of natural mode are harmonic and melodic modes (Fig. 3 and 4).
Harmonic major - the VI step is lowered. The sound of the upper tetrachord takes on an oriental tinge.
Melodic major - VI and VII steps are lowered. Lowering these steps leads to the fact that the upper tetrachord of the major becomes minor (has the structure of the upper tetrachord of natural minor) and acquires a melodic sound.
Rice. 3. Types of major frets
Harmonic minor - the 7th step is raised. An increase in the VII degree leads to the appearance of an oriental shade in the upper tetrachord and an increase in the inclination of this degree to the tonic. The upper tetrachord in harmonic minor sounds more intense than it does in natural minor.
Melodic minor - raised VI and VII steps. Increasing the VI degree allows you to smooth out the transition from the V to the VII elevated degree (increased second) and gives the upper tetrachord melodiousness.
Rice. 4. Types of minor frets
The steps of the fret have their own names, and some have a letter designation. The sequence numbers of the steps are indicated by Roman numerals:
I step - tonic, T (main note)
Stage II - descending introductory sound (allowed to the tonic by lowering)
Stage III - mediant or upper mediant (from the Latin media - middle, since it is in the middle between I and V steps above the tonic)
Stage IV - subdominant, S (the Latin prefix sub means under)
Stage V - dominant, D (from the Latin "dominant"). This sound is the highest.
VI degree - submediant or lower mediant (located in the middle between IV and I degrees and is located below the tonic)
Stage VII - ascending introductory sound (allowed to tonic by increasing)
According to the functionality, the steps of the fret are divided into main and secondary. I, IV and V are the main steps of the mode, and II, III, VI and VII are secondary. From the main steps, the main chords of the mode are built, which will be discussed later. For now, just remember them.
Rice. 5. Main and side steps of the mode
Each step of the mode is characterized by a degree of stability. We can say that an unstable sound is a comma in a sentence, and a stable sound is a period. The instability of sound by ear is expressed in the fact that when it appears, tension arises, which one wants to eliminate by playing a stable sound. Unstable sounds tend to be attracted to stable sounds, just as objects on the surface of the earth are attracted to the globe. The transition from an unstable sound to a stable one is called resolution.
Rice. 6. Stable and unstable modes
The stability and instability of the steps are different. The most stable step is the 1st step of the mode (tonic). Stages III and V are much less stable. Unstable stages are II, IV, VI and VII. The degree of attraction of unstable steps to stable ones is different. It depends on:
- degree of sustainability of sustainable sound
- the interval formed between unstable and steady sound. Halftone gravitation is more pronounced than tone.
In the case of a natural major, the situation is as follows:
- VII -> I - the strongest gravity, since the I degree (tonic) is the most stable sound in the mode, and the gravity is semitone
- II -> I is stronger than II -> III, since stage I is more stable than III
- halftone gravity IV->III is stronger than tone IV->V
- VI is allowed only in V, since VII is an unstable stage
Stages II and IV have two permits, stages VI and VII have one each (Fig. 6). Knowing the relationship between stable and unstable steps allows you to play the simplest motifs (the smallest possible meaningful fragment of a melody): first, an unstable sound is played, and then it resolves into a stable sound.
In the fret system, the sound acquires new characteristics - the degree of stability and functionality. The mode itself is included in the tuning system, and the tuning is included in the scale system (Fig. 7).
Rice. 7. Relationship between sound and its surrounding systems
Intervals and mode
The interval consists of two steps, so the stability of the interval will depend on the stability of the steps included in it. Tritones have the greatest instability and tension in sound. In the natural major and minor modes there are two of them: a reduced fifth of the VII-IV steps and an increased fourth of the IV-VII steps. The interval VII-IV resolves into a major third I-III, and the interval IV-VII into a minor sixth III-I.
Intervals can be built either from the given note, or in a given tone. On the previous page, all simple intervals built from the step before. in kind in C major there are no steps that correspond to black keys, so in this key impossible(without using chromatisms - raised or lowered steps) build intervals from the step before, which includes the black key. But this does not mean that, for example, there is no minor second in natural C major. Such an interval exists and is built from the III and VII steps: mi-fa, si-do. Building intervals without relative to key is an exercise. Practical use is given by the ability to build intervals in the key. If chromaticisms cannot be used, then the construction of an interval in the key can only be done using diatonic steps.
In music, as already mentioned, everything is relative. The new environment can make additions and adjustments. By now, you know that intervals can exist in the scale system (they can be built from any degree of the scale) or in the mode system in one key or another (intervals are built on diatonic degrees). In the scale system, the main characteristic of the harmonic interval is the nature of its sound (consonant and dissonant intervals). In the mode system, intervals acquire a new important property - functionality.
Figure 8. shows two intervals - a pure fourth and a pure fifth. Steady steps of the mode are highlighted in green.
Rice. 8. Intervals from the first step of the natural major mode (C-major)
Both of these intervals are included in the same group - intervals of perfect consonance, and for this reason it is impossible to determine in the scale system which of these intervals sounds more melodic. Than intervals built from a step before, differ from the same intervals built from the foot re? Nothing, if you do not take into account the interval of frequencies included in them.
If we consider these intervals in the mode system, then it is correct to say that they are not built from a step before, and from the I-th step of the fret. A pure fifth is formed by stable steps of the mode - I and V, and a pure fourth - by stable and unstable - I and IV. In the fret system, the intervals formed by stable steps sound, accordingly, less tense. A pure fifth from stage I sounds more stable (less tense) than a pure fourth. That is, the mode system made it possible to see the difference between the considered intervals.
On fig. 9. shows the same intervals, but built from the second degree of the mode.
Rice. 9. Intervals from the II degree of the natural major mode (C-major)
Now the fifth is formed by the unstable steps II and IV, and the stable step (V) enters the fourth. Now the fourth sounds more stable than the fifth.
The functionality of intervals is most clearly demonstrated by the example of minor and major thirds. In the scale system, these intervals refer to imperfect consonance, that is, in terms of the degree of euphony, they are inferior to a pure fourth and fifth. However, in the mode system, these intervals determine the type of triad: if the first interval in a triad is a major third, then a major sound is obtained, but if the first interval is a minor third, then a minor sound is obtained. A perfect fourth is not used in a triad, and a perfect fifth does not affect the appearance of the chord. The question arises, which characteristic has a higher priority in the fret system - the degree of harmony or functionality? In the mode system, the functionality of the interval is of great importance.
Relationship of keys
From 12 chromatic steps of the octave, you can build a large number of major and minor keys. In practice, they are limited to 15 major and 15 minor keys, guided by the principle of reasonableness. Why complicate things when the same thing can be done simply? No one forbids, for example, the use of the tonality of B sharp major (Fig. 10).
Rice. 10. Key in B sharp major
Try to play this scale (crosses in front of the steps - double sharp - increase by 1 tone). Not easy? But in fact it is the key of C-major . In C major there are no signs at the key, and in the key of B sharp major there will be twelve of them.
How to learn to build any key without memorizing them? First, you need to remember the order of the characters in the key. Sharps follow in this order: f-do-sol-re-la-mi-si. Flats follow in this order: si-mi-la-re-sol-do-fa. Secondly, you need to remember well the tonal structure of the major and minor modes. Thirdly, you need to remember that the major and minor modes are modes consisting of seven diatonic steps.
Example 2. It is required to build the key of E-major and determine the signs for it. Recall that the major mode has a tone structure "b-b-m-b-b-b-m". After that, we begin the construction of the E-major key from the note E:
There are four sharps in the key of E major: F, C, G, D.
Example 3. It is required to build the key in E minor and determine the signs for it. Recall that the minor mode has a tonal structure "b-m-b-b-m-b-b". After that, we begin the construction of the E-major key from the note E:
In the key of E-minor, there is one sign - F-sharp. Why F-sharp and not G-flat? Because the last one would be:
That is, instead of seven steps, six steps are used, and the minor scale should consist of 7 steps. In addition, in diatonic, a transition with skipping a step is not allowed, and in this example a step is skipped F.
Example 4. It is required to build the key of F-major and determine the signs for it.
In the key of F major, one sign - b flat
15 major keys - also a lot. Why do we need so many major keys? From the point of view of construction, all major modes are the same and have the same interval composition (b.2, b.2, m.2, b.2, b.2, b.2, m.2). But from the point of view of the nature of the sound, one major mode is different from another major mode. It is easy to check this using the formula for determining the frequencies of steps in an equal temperament system F=440*2 i/12. Let's determine what frequency range is enclosed in one tone between steps of the first octave la And si,do and re. In the first case 440*2 0/12 - 440*2 1/12 = 53,8833 Hz, and in the second 440*2 -9/12 - 440*2 -7/12 = 32,0392 Hz. The difference is visible to the naked eye. In practice, this means that a song in one major key will sound more cheerful and brighter than in another major key. The same can be said about any tone. The transition to a different key during transposition does not change the harmony, but leads to a change in the color and character of the sound of the composition. You can check this by comparing the sound of a midi file in different keys.
