A small test on basic knowledge of music theory (questions on music theory knowledge) 1. Questions on music theory knowledge

Question 1:

The first interval is a doubled fourth interval (note that it is not the "diminished fourth" mentioned above, "diminished fourth" and "doubled fourth" are different interval), is a modified interval (intervals that can be composed of basic tone levels are natural intervals, intervals that cannot be composed of basic tone levels are changed intervals), and are dissonant intervals (any increasing, decreasing, doubling, and doubling intervals are not Consonant intervals, no exceptions).

The second interval is a pure twelfth interval, which is a natural interval and a consonant interval (any pure interval is a consonant interval, without exception).

The third interval is a diminished octave, which is a change interval and a dissonant interval.

The fourth interval is the major sixth interval, which is a natural interval and a consonant interval.

Note: The C staff only affects the level of the note itself, but does not affect the name of the interval (that is, the type of interval). Therefore, when judging the name of the interval (that is, the type of interval), it does not matter what kind of spectrum it is. Tables can be viewed as G staff or F staff, which can save time in solving problems.

The fifth interval is the minor thirteenth interval, which is a natural interval and a consonant interval.

Note: Twelve degrees are similar to fifth degrees, thirteenth degrees are similar to sixth degrees, and so on. Don’t be overwhelmed when you see an interval larger than an octave.

Question 3:

Sorry, your picture doesn’t show it, so I can’t see this question... Why don’t you post another one...

In fact, these are very basic questions and are not difficult. You can find this knowledge in any music theory book. When doing questions about intervals, you must grasp the two aspects of the interval, the number of notes and the degree. These two aspects determine the nature of the interval, so neither one can be missing. When doing questions about the construction of ***, firstly, you must distinguish the bass and the root note, and secondly, you must define the definition and different names of each *** (such as the big seven***, also called the big seven***, and the diminished seven***). Seven*** is also called half minus seven***, etc.) Keep in mind that if you grasp these two points, you will be able to understand the problem of constructing *** with ease.

If you still don’t understand anything, you can continue to ask.

2. Music theory knowledge (questions and solutions) Urgent

Basic music theory knowledge (1) Sound 1. The production of sound: Sound is a physical phenomenon.

When an object vibrates, it produces sound waves, which travel through the air to people's eardrums and are reflected by the brain and perceived as sound. The sound that people can hear vibrates about 16-2000 times per second. In nature, our human hearing can sense many sounds, but not all sounds can be used as music materials.

The tones (excluding overtones) used in music are generally limited to the range of 27-4100 vibrations per second. That is to say, the sounds mentioned in music are selected by people in their long-term life practice, can express people's lives or thoughts and feelings, and form a fixed system to express musical ideas and shape musical images.

2. The main properties of sound: high and low, strong and weak, long and short timbre (1) Sound has four main properties: high and low, strong and weak, length and timbre, which are very important in music performance. Among them, the pitch and length of the sound are the most important. I don’t know if you have this experience: For a song, no matter whether you sing it with a human voice or play an instrument, whether the voice is small or loud, and no matter what key you use when singing or playing, the strength and timbre of the sound are different. Changes, but the melody of the song remains the same.

However, if the pitch or length of the sound of the song changes, the experience of the music will be seriously affected. It can be seen that for a melody, the importance of pitch and sound length.

(2) The pitch of the sound is determined by the number of vibrations (frequency) of the object in a certain period of time. The more vibrations, the higher the sound; the fewer vibrations, the lower the sound.

The strength of the sound is determined by the amplitude (the amplitude of the vibration of the sound). The larger the amplitude, the stronger the sound; the smaller the amplitude, the weaker the sound.

The length of the sound is determined by the duration of the sound. The longer the duration of the sound, the longer the sound; the shorter the duration of the sound, the shorter the sound.

The timbre is determined by many factors such as the nature, shape and number of overtones of the pronunciation body. (3) What is timbre? Timbre refers to the sensory characteristics of sound.

It is an important means of expression in music that is extremely attractive and can directly touch the senses. The vibration of the sound body is composed of a variety of harmonics, including fundamental tones and overtones. The number of overtones and the relative intensity between overtones determine a specific timbre.

People’s ability to distinguish timbre is innate, and timbre is divided into vocal timbre and instrumental timbre. The vocal timbres are high, medium and low, and are divided into male and female ones; the instrumental timbres are mainly divided into string instruments and wind instruments, and the timbres of various percussion instruments are also different.

3. Classification of sounds Musical noise Noise According to the regularity and irregularity of the vibration state of the sound, the sound is divided into two categories: musical sound and noise. Music is mainly used in musical sounds, but noise is essential in musical performance.

For example, the sound made by a drum set is a kind of noise, but this noise has certain rules. (2) Scale Pentatonic Scale Heptatonic Scale 1. Definition of scale Scale refers to each note in the mode. Starting from a certain pitch, that is, starting from the tonic, the notes are arranged from low to high in order of pitch. , such a sequence of notes is called a scale. There are many different scales around the world. With the advancement of music level, music has a very complete theory and system. At present, almost all the world uses the Western Twelve Equal Temperament as a way to learn music. The basis, so what we call scales today is based on the most common major scale (major key) and minor scale (minor key).

2. Classification of scales According to the number of tones contained in the mode, it can be divided into: "pentatonic scale", "septatonic scale", etc. The scale from low to high is called ascending, and the scale from high to low is called descending.

Pentatonic scale is a scale composed of five tones. It is mostly used in folk music modes such as: do, re, mi, sol, la, (do). (3) Musical sound system 1. Definition of musical sound system The sum of sounds with fixed pitches used in music is called musical sound system.

2. Classification of musical sound system (1) Sound sequence The sounds in the musical sound system are arranged in ascending or descending order, which is called sound sequence. (2) Sound level Each sound in the musical sound system is called a sound level.

There are two types of sound levels: basic sound level and modified sound level. In the musical sound system, seven tone levels with independent names are called basic tone levels.

The names of the basic sound levels are marked by letters and roll calls. Two adjacent notes with the same name are called octaves.

The sound obtained by raising or lowering the basic pitch level is called a modified pitch level. Raising the basic tone by a semitone is marked with "rising" or " "; lowering it by a semitone is marked with "falling" or " "; raising a whole tone is marked with "re-rising" or "x"; lowering a whole tone is marked with "re-falling" " or " " is indicated; restoration is indicated by " ".

3. Sound range and sound range Sound range can be divided into general sound range and individual sound range, human voice and musical instrument range. Part of the vocal range is the sound zone, which can be divided into three types: treble zone, mid-range zone and bass zone.

The division of vocal ranges of human voices is often inconsistent. For example, the high range of a bass is the low range of an alto.

However, each sound zone has its own characteristic timbre, which is reflected in the performance of music. Generally speaking: the high-pitched zone is crisp and sharp; while the low-pitched zone is deep and deep.

(4) Modes of stable tones and unstable tones In music, it is difficult to express musical ideas and shape musical images by relying only on an isolated note, *** or multiple tones that have no relationship with each other. realized. 1. Definition of mode In music, many tones (generally no more than seven) connected together according to a certain relationship form a system with one tone as the center (the main tone). This system is called mode.

2. Classification of modal midtones In the modal system, the tones that play a supporting role and give people a sense of stability are called stable tones. Sounds that give people a sense of instability are called unstable sounds.

Unstable sounds have the characteristic of progressing to stable sounds. This characteristic is called a tendency. Instability proceeds to a stable tone according to its tendency, which is called resolution.

Sound stability and instability are relative. A common note (or ***) is stable in a certain mode system, but may become unstable in another mode system. Even in the same mode system, due to different harmonic processing, a certain tone may become unstable in another mode system. Some stable sounds may also be temporarily unstable.

3. Classification of modes Modes are divided into major modes and minor modes. A mode composed of seven tones is called a major mode, in which the stable tones combine to form a major third ***.

The minor mode is also composed of seven tones, among which the stable tones combine to form a minor third ***. The tonic of the major mode and the third note above it are major thirds because of this interval.

4. How about these questions on music theory knowledge?

The first question: The first interval is a doubled fourth interval (note that it is not the "subtracted fourth" mentioned above, "subtracted fourth"). "Fourth" and "doubled fourth" are different intervals), which are changing intervals (intervals that can be composed of basic tone levels are natural intervals, intervals that cannot be composed of basic tone levels are changing intervals), and are dissonant intervals ( Any augmented, diminished, multiplied, or doubled interval is a dissonant interval, without exception).

The second interval is a pure twelfth interval, which is a natural interval and a consonant interval (any pure interval is a consonant interval, without exception). The third interval is a diminished octave, which is a change interval and a dissonant interval.

The fourth interval is the major sixth interval, which is a natural interval and a consonant interval. Note: The C staff only affects the level of the sound itself, but does not affect the name of the interval (that is, the type of interval). Therefore, when judging the name of the interval (that is, the type of interval), no matter what kind of staff it is, it can be regarded as G staff. Table or F staff, this can save time in solving problems.

The fifth interval is the minor thirteenth interval, which is a natural interval and a consonant interval. Note: Twelve degrees are similar to fifth degrees, thirteenth degrees are similar to sixth degrees, and so on. Don’t be overwhelmed when you see an interval larger than an octave.

6. What are some little knowledge about music theory?

Little knowledge about music theory (1) 1: Tone is a physical phenomenon.

When an object vibrates, it produces sound waves, which travel through the air to the eardrum and are reflected by the brain and are perceived as sound. The sound that people can hear vibrates about 16-2000 times per second, and the sounds used in music (excluding sounds) are generally limited to the range of 27-4100 vibrations per second.

The pitch, strength, length and timbre of the sound depend on the vibration of the object. 2: Tone-color refers to the sensory characteristics of sound.

The vibration of the sound body is composed of a variety of harmonics, including fundamental tones and overtones. The timbre is determined by the number of overtones and the relative intensity between the overtones. People's ability to distinguish timbre is innate. The color of music is divided into vocal timbre and instrumental timbre.

The vocal timbres are divided into high, medium and bass, and are divided into male and female; the instrumental timbres are mainly divided into string instruments and wind instruments, and the timbres of various percussion instruments are different. 3: Resonance Resonance refers to a kind of vibration.

When a sound-producing body vibrates, it causes other objects to vibrate and emit sound, producing a buzzing sound. 4: Fundamental tone The lowest frequency sound emitted when an object vibrates is the fundamental tone, and the rest are overtones.

The fundamental note determines the pitch. 5: Harmonic overtone: In addition to the lowest sound produced by the overall vibration of the sound body, which is the fundamental tone, and based on the fundamental tone, the remaining 1/2, 1/3, 1/4 and other parts also vibrate at the same time and are overtones.

The combination of overtones determines a specific timbre and allows people to clearly feel the loudness of the fundamental tone. Musical instruments and all sounds in nature have overtones.

6: Pitch (Pitch) Pitch is expressed by the number of vibrations in one second. The higher the frequency, the higher the pitch; the lower frequency, the lower the pitch.

The current internationally accepted standard sound "a" is a sound that vibrates 440 times per second. 7: Pitch name Pitch name refers to the name that represents a fixed pitch in the Western music system.

These names are not unified and vary from country to country. The most widely used ones are: C D E F G A B.

8: Syllable names Syllable names refer to the names of each note on the scale. Usually 1do, 2re, 3mi, 4fa, 5sol, 6la, 7si are used.

The tonic in a major key is 1do, and the tonic in a minor key is 6la. 9: Sound range (pass) The range between the lowest and highest notes that a human voice or musical instrument can achieve is called the sound range.

The vocal range can be divided into the total vocal range and individual vocal ranges, vocal and musical instrument ranges. 10: Tonality Tonality refers to the mode category and tonic height.

In music, the tonic is the core of melody and harmony, and other sounds are subordinate to it and finally end on the tonic. Such music is tonal music.

Little knowledge about music theory (2) 11: Scale (Scale) refers to each note in the mode, starting from a certain pitch, that is, starting from the tonic, and moving the notes in order from low to high. To arrange, such a sequence of sounds is called a scale. The scale from low to high is called ascending, and the scale from high to low is called descending.

The scales we are talking about today are based on the most common major scale (major key) and minor scale (minor key). 12: Pentatonic scale A scale composed of five tones.

Mostly used in folk music. Such as: do, re, mi, sol, la, (do).

13: Major mode A type of mode. In the seven-tone scale, the distance between adjacent two tones is divided into two types: whole steps and semitones.

Except for the semitone between the third and fourth tones and the semitone between the seventh and eighth tones, the rest of the scale is a whole tone. The colors in major keys are brighter.

14: Minor mode is a type of mode. The heptatonic scale has four forms: "natural minor", "harmonic minor", "melodic minor" and "modern minor scale". The colors of minor keys are generally darker than those of major keys, and are often used to express sadness and melancholy.

The space between the second and third notes of the natural minor (minor scale) and the fifth and sixth notes are semitones. 15: Just intonation is different from the twelve equal laws.

The relationship between each tone and the tonic tone in the scale is a pure interval. Since the semitones formed in this way cannot be divided into equal parts, they cannot be modulated casually and have been eliminated by history.

16: Key-note The first note in the modal scale. A type of Temperament.

Divide an octave into twelve semitones, and the intervals of the semitones are all equal. Pianos, harps and other musical instruments are all tuned according to this temperament.

17: Semi tone, whole tone (Semi tone, Whole tone) Divide an octave into twelve equal parts, each part is a semitone, and two semitones are equivalent to a whole tone. A semitone is equivalent to a minor second, and a whole tone is equivalent to a major second.

18: Consonant and dissonant intervals (Consonant, Dissonance) According to the degree of consonance, it can be divided into complete consonant intervals (pure 1, 4, 5, 8 degrees) and incomplete consonant intervals (major, minor) 3, 6 degrees). Other than that it's all dissonance.

19: Interval refers to the distance between two notes. The unit used to calculate musical intervals is called "degree", and the number of syllables between two sounds is called "degree".

Intervals with the same degree can be differentiated into pure, major, minor, increased, or decreased due to the different numbers of semitones and whole tones they contain. 20: Twelve-tone system (tweleve-tone system, tweleve-note system) is one of the modern composition techniques.

It was founded in 1921 by Austrian composer Schoenberg. The composer abandoned the traditional mode, tonality and harmony system, arbitrarily arranged the twelve tones in the chromatic scale into a year-long sequence, and then processed them with techniques such as inversion and retrograde. Unless all the tones have appeared, otherwise No sound may be repeated.

Little knowledge about music theory (3) 21: Pentatonic scale There are five tones in an octave, which is called "pentatonic scale". 22: Diationic scale. There are seven notes in an octave, which is called a "seven-note scale".

23: Dynamics (dynamics) Dynamics refers to the intensity of the sound when playing and singing music. Expressed by velocity symbols, such as f (strong), p (weak), < (crescendo), > (decrescendo), etc.

26: Indefinite pitch (indeterminate pitch) The sound used in the music without a clear pitch is called indefinite pitch. It is actually noise and does not belong to the scope of the music.

Modern composers often use sounds such as the sound of sawing wood, folding paper, typing, sweeping, tapping, hissing, whistling, etc. 27: Asymmetric rhythm (asymmetric rhythm), also known as "polyrhythm" (polyrhythm).

In the same phrase or measure, each voice.

7. Give me some basic music theory knowledge

The black note is called "quarter note".

It is half a note smaller than a half note. (It is equal to the duration of 1/4 of a whole note. An eighth note is half of a quarter note.

In the beat, many notes are measured in units of one beat. (This is also called "unit "beat"), this important time period - one beat, is the basis of music, which is represented by designated notes. That is, using various different notes, such as half notes, quarter notes, eighth notes, etc. Wait, as a basic beat, and then gradually progress from strong to weak.

Next, I will use the most popular way to explain what a beat is. In simple words, you use the palm of your hand. Come and shoot.

If you use two hands to shoot together, it is called a shot. If you shoot with two hands, it is called a shot. When you lift it up, it's also half a beat. In this way, the up and down steps add up to one beat (equal to half a beat plus half a beat). In Chinese opera, the beat is usually called "ban, eye", and "ban" means heavy beat. , "eye" is the weak beat.

The way to beat the beat is as follows: slap it with your palm, which is called "ban", and then tap it with your index finger, which is called "eye". What does "Three Eyes Slowly" often mean in Peking Opera? This "Three Eyes" means there are three weak beats, plus one strong beat, which actually refers to 4/4 beat.

If a person sings in a "no matter what" way, it means that the person's rhythm is not good and the time is not accurate.

The beat of music is determined according to the requirements of the music. For example, if the required speed of the music is 60 beats per minute, then the time occupied by each beat is one-sixtieth of the minute, which is one second, (half a beat is One-half second), if the specified speed is 120 beats per minute, then each beat takes up half a second (half a beat is 1/4 second), now it is half a second to beat, the previous One beat per second, obviously the latter is faster than the former (we will talk about it later in the section about speed), and so on.

This is the duration of the beat. When the duration of the beat is determined, for example, when a quarter note is one beat, an eighth note is equivalent to a half beat, a whole note is equivalent to 4 beats, and a half note The note is equivalent to two beats. The sixteenth note is a 1/4 beat. In other words, there is one quarter note, two eighth notes, and four 16th notes in one beat.

For example, if an eighth note is one beat, a quarter note is two beats, a half note is four beats, a whole note is eight beats, and a sixteenth note is half a beat. In this way, when the beat After the time value is determined, the notes of various time values ??are connected with the beat. Such as 2/4 beat.

One beat is a quarter note, and each measure has 2 beats. It is called 2/4 time. There are two beats in a measure, the first beat is a strong beat and the second beat is a weak beat.

In one measure, only one strong beat and one weak beat appear, and then they repeat in each measure. This 2/4 rhythm is very suitable for use when marching in queue, so most marches adopt this 2/4 time form.

"Ratto"--also called "rocker arm". The internal parts of low-end automobile engines are connected with the valves and are also called "valve rocker arms".
