How is the instrument tuned? What is the difference between the keys?

1. Musical instruments are toned in tonality.

Tonality is a general term for the main tone and key category of the key, for example, the major key with C as the main tone is "C major, and the minor key with A as the main tone is the "A minor".

Wait. By analogy, there are generally 24 main tonality in **.

The difference between the keys is shown in the following diagram:

The first question is how the instrument is tuned. cdefgab plus their varying scales, that is, rising and descending, a total of twelve tones, you must first figure out the twelve equal temperament, there are a total of twelve tones, who is the main tone, then what is the tune of this piece. The piano is a bit more versatile and can play any tune because it has a wide range.

String instruments can be tuned, in the guitar, the open string tone of each string is fixed (special tunes also need to be tuned), and on the basis of EADGBE, we can play C or D. The vocal range of flutes and gourds is narrower, and there are flutes and gourds in C and D tones. The tunes of their own are set.

The second question, the difference. In the same octave range, the do in D is a little higher than the do in C, because 1 in D is 2 in C.

I'm here from an amateur's point of view, and I don't know if I can help you, but in fact, music theory is very complicated, and I can't explain it clearly in a word.

The difference is big, Western instruments have cdefgab, and Chinese have pentatonic mode!

The pitch is mainly determined by the frequency of the sound and is also related to the intensity of the sound.

The level of sound frequency is called pitch, which is one of the three main subjective properties of sound, namely volume, pitch, and timbre. It indicates the degree to which a person's hearing can distinguish the tone of a sound.

The tone can be quantitatively judged. The unit of tone is called beauty: take the tone of a pure tone with a frequency of 1000 Hz and a sound pressure level of 40 decibels as the standard, called 1000 America, and some pure tones, which sound twice as high as the tone is called 2000 America, and the tone that is twice as low as 500 America, and so on, can establish a tonal scale within the entire audible frequency.

Tone control is to artificially change the proportion of high and low frequency components in the signal to meet the listener's preferences, render a certain atmosphere, achieve a certain effect, or compensate for the lack of sound in the speaker system and the sound playback place.

This control process does not actually change the pitch (frequency) of the various sounds in the program, the so-called "pitch control" is just a customary name, in fact, "high and low pitch control" or "pitch adjustment".

The order of tone from high to low is C, D, E, F, G, A, B, and generally the key of boys is between e and f.

In music theory, different octaves are determined, and "big character n group" and "small word n group" are used to mark, the first note of each group is c, and the last note is b, which is the arrangement of the landlord, not the lowest A and the highest G.

The values of the components that make up the tone circuit must meet the following relationships:

Compared with the resistors, the capacitive reactance of C1 and C2 is small enough at high frequency and large enough at medium and low frequenciesThe capacitive reactance of C3 and C4 is small enough at high and medium frequencies and large enough at low frequencies. C1 and C2 can make the high-frequency signal pass through, but not the medium and low-frequency signalsC3 and C4 let both high and medium frequency signals pass, but not low frequency signals.

Tonality is a general term for the main tone and key categories of the key, for example, the key of a major mode with C as the main tone is "C major", and the key of a minor key with A as the main tone is "A minor". And so on, in general, there are mainly 24 tones of trembling holes.

Pitch refers to the pitch of the music, which is determined by the frequency of the sound source Analysis: To solve this problem, you must know that the pitch has three characteristics: pitch, loudness and timbre, know that the pitch is related to the vibration frequency of the sounding object, the greater the frequency, the higher the pitch.

Answer: Solution: The three characteristics of musical sound are loudness, timbre, and pitchThe pitch is related to the vibrational frequency of the emitter, and the faster the frequency of the object, the higher the pitchSo the answer is: tone;Frequency.

1) Pitch: It refers to the height of the sound, which is related to the frequency of the emitter.

2) Loudness: refers to the magnitude of the sound and the amplitude of the emitter.
