Does the standard piano have 88 keys, and each key has a different sound?

Electronic keyboards generally only have fewer high-pitched keys or very low-pitched keys than ...... pianosGenerally, normal songs do not have such a wide vocal range, and there is no obstacle to playing.

I saw another master who used a supermarket toy piano as an electronic piano.

To give you these two posts, look at it and you will understand, don't use a 200 electronic keyboard to compare a 20,000 piano with a 20,000 piano, and it is not recommended to use a 20,000 electronic keyboard to compare a 100,000 piano, because the electronic organ is not born to imitate the piano, and the piano will not be replaced by the electronic keyboard, and the two are keyboard instruments of their own, don't assume because the keyboard is arranged.

If you haven't seen a real electronic keyboard, don't talk nonsense, you don't understand, and mislead others.

There are many ways in which an electronic organ is different from a piano. If you buy an electronic keyboard, of course, you can finish playing the score. But if you're buying a piano, it's hard to tell.

A lot of tunes can not be played on the electronic organ, and also, the piano music and the electronic organ are too ugly to play, although the two instruments are a bit similar, but how can this be compared, the vocal range is not the same, the timbre is not the same, and the gap is so big. Besides, I have heard that the piano can cultivate temperament and cultivate sentiment. I've never heard of an electronic keyboard.

In short, what to play depends on your actual needs.

It must be 88 keys, otherwise you can't play your favorite tune, wouldn't it be wronged?

The electronic organ is not the same thing as the piano: the piano sound quality is good, the electronic organ is so ugly, and the volume cannot be controlled, the electronic organ is incomplete, and the piano music cannot be played The electronic organ sounds lightly, and the piano must be pressed very hard to play.

The piano generally has 88 keys, which reduces the number of keys by 20 compared to 108 keys: the bass part is reduced by 9 keys, that is, the 1st to 9th keys; The treble part is reduced by 11 keys, i.e. from the 98th to the 108th key.

The frequency range of the piano is from Hz to 7902 Hz for the entire 108 keys, while the frequency range for the 88 keys ranges from Hz for 0 A0 keys to 4186 Hz for 8 C8 keys. The comparison table between the large staff and the piano keyboard is as follows:

On an 88-key piano, the music system is to arrange the 7 white key basic tone levels cdefgab and their 5 black key variation scales into a sound group, with a total of seven and a third tone groups, divided into two categories: large and small character groups, arranged in order from low to high.

The order of the names in each group is the same, except that the sequence number of each group is added to the right side of the name (uppercase at the bottom right and lowercase at the top right). The markings for each sound group are: large character group 2 (only 3 sounds) - large character group 1 group - large character group - small character group - small character group 1 group - small character 2 group - small character 3 group - small character 4 group - small character 5 group (only 1 sound).

A set of scales (including the twelve scales of the basic and variable scales - from c to b) in the piano is a "small word group". It is represented by lowercase letters C, D, E, F, G, A, B, and marked with the Arabic numeral 1 at the top right of it. Such as:

c1、d1、e1、f1、g1、a1、b1。

In the same way, name the other sound groups:

1. The sound groups that are higher than the group of small characters are named "small character group 2", "small character group 2", "small character group 3", "small character 4 group", "small character 5 group", "small character 6 group" and so on. and use the Arabic numeral 1 or at the bottom right of it. For example, the D of the third group of small characters is marked as D 3, and the be of the second group of small characters is marked as B e 2, and so on.

2. The sound groups that are lower than the group of small characters are named "small character group", "large character group", "large character group", "large character group", "large character group 2", "large character 3 group", "large character 4 group" and so on.

The sounds of large groups of characters are represented by the capital letters c, d, e, f, g, a, b, and the Arabic numeral 1 or at the bottom right of it. For example, the D of the second group of large characters is marked as D 2, and the BA of the third group of large characters is marked as BA 3, and so on.

The differences are as follows: 1. The keys are different: 85 keys, there are 6 groups of keys, of which the first to fifth groups are complete from the left, each group has 12 keys, and the rightmost group is incomplete, with only one C (that is, the DOL in C key) key.

The 88-key piano keyboard is composed of 88 keys with black keys and white keys. where the black keys.

36 and 52 white keys.

2. Different vocal range: the keys on the keyboard actually represent its vocal range, because an octave has a very wide range on multiple keyboards, while 61 is not so wide.

3. Different touch: 88 keyboard piano.

is a standard keyboard. You can play grand piano music, like 88 keys, which will add a weighted feel. The 85 keyboard is an ordinary piano, and the keys are relatively light and can imitate the timbre of many instruments.

The keyboard of the standard piano is made up of 88 keys, black and white. Among them, there are 36 black keys and 52 white bonds. The distribution and arrangement of the black and white keys show a regularity.

That is, the black keys are two in groups and three in groups. The position of the tone is the seven letters of the sound name, i.e. cdefgab, from left to right, each passing through a group of sounds, one octave higher than the previous group.

The name of each key is named by the dominant note in its scale, that is, what key it is, and the letter in that key name is the name of the "1" of that key. If you have to find it by the simple notation, you can calculate it yourself.

The standard 88-key piano is a group of the total tone column of the music system, which is called "small character group".

C1, C 1, D1, D 1, E1, F1, F 1, G1, G 1, A1, A 1, B1, refer to the drawings below.

The tall group adjacent to the small character group is called the "small character group two".

c2, c#2, d2, d#2, e2, f2, f#2, g2, g#2, a2, a#2, b2 .

The tall group adjacent to the second group of small characters is called the "three groups of small characters".

c3, c#3, d3, d#3, e3, f3, f#3, g3, g#3, a3, a#3, b3.

The tall group adjacent to the three groups of small characters is called the "four groups of small characters".

c4, c#4, d4, d#4, e4, f4, f#4, g4, g#4, a4, a#4, b4.

The tall group adjacent to the four groups of small characters is called the "five groups of small characters". There is only one tone in the five groups of small characters.

c5.The low group adjacent to the small character group is called the "small character group". Marked with lowercase letters. Such as:

c, c#, d, d#, e, f, f#, g, g#, a, a#, b.

The low group adjacent to the small group is called the "large group". Marked with capital letters.

c, c#, d, d#, e, f, f#, g, g#, a, a#, b.

The low group adjacent to the large character group is called the "large character group". Its markings are:

c1, c#1, d1, d#1, e1, f1, f#1, g1, g#1, a1, a#1, b1.

The low group adjacent to the group of large characters is called the "second group of large characters". There are only three tones in the second group of large characters.

a2, a#2, b2.

The second group of large characters and the fifth group of small characters are incomplete sound groups.

A complete group of tones with a total of twelve different pitches and pitches.

The sound area in the piano is usually divided into three types: low, medium and high. The 88-key upright piano commonly used in the home is no exception, usually starting with the bass key 1 (the leftmost string), to the 27th key (string) for the bass, and the 28th key (string) to the 58th (string) for the middle range. Keys 59 (strings) to 88 (strings) are the treble.

On some pianos, the bass area is increased by one string group (i.e., 28 strings), and the middle range is reduced by one string group (i.e., 29 strings), that is, the bass area starts from the first key and ends at the 28th key group, and the middle range starts from the 29th key group to the 58th key group; The treble is divided from 59 to 88, as in the previous division. In small and medium-sized upright pianos, it is common to see 30 strings in the bass range, 30 strings in the middle range, and 28 strings in the upper register.

Every twelve notes (keys) in the piano's vocal range are grouped, such as C1, C1, D1, D1, E1, F1, F1, G1 of a large group of B in a large character group. Twelve notes (keys) of G1, A1, A1, B1.

When the 88 keys of a standard piano are divided into groups, there are 7 groups.

From the left and right of **c, a group of small characters in the phonetic sequence ** is called a small character group, its phonetic level marks are represented by lowercase letters and the number 1 is added at the top right, such as c1, d1, e1, etc., the group higher than the small character - group is named in order, small character two groups, three groups, four groups, example two groups c2, d2, e2, and so on, from **c to the left, the small word group is marked without numbers, with lowercase letters c, d, e, large characters are not represented by numbers, such as c, d, e, The first to second groups of large characters are represented by numbers at the bottom right of the group, such as c1, d1, e1,,, don't understand me again!

Don't you know all about it? It's cdefgab. Each group of cdefgab is called an octave.

It's just that each octave is different. The bass is deep and the treble is clear.

In fact, all you need to know is an octave.

c d e f g a b c

It's an octave.

And then keep repeating.

That's what we say, one octave, two octaves.

These are the names of the white keys.

Didn't know? Help the top down.

At present, the vibration frequency of the international standard tone is 440Hz per second.

Each note has a fixed frequency, and the vibration frequency of the standard note is more comfortable. With the development of technology, radio stations appeared, contributing to the current standard pitch of a 440Hz.

Historically, the pitch of the standard tone has appeared in 465Hz, 380Hz, 409Hz, etc. For example, Mozart liked to use a 422Hz, and the United Kingdom used to use a 380Hz.

The standard pitch can only be used as a suggestion in practice, and different orchestras will also adjust different pitches as standard pitches based on the actual situation, such as A 442 Hz, A 444 Hz, etc. On the piano, the standard note is the la (6) sound in the **c group (small character group), so you can find the standard note by finding the small character group.

This question seems troublesome, but it's actually very simple, I'll give you a way, you can know it as soon as you know it, as long as you know one of the others, you will know it.

Don't we all know that the A of the small character group is 440 Hz, and we also know that the octave is a multiple, that is, the A of the small character group 2 is 880 Hz, which means that the difference between A1 and A2 is 440 Hz.

We also know that although the production of the rhythm of the fifth is symbiosis, it is still the law of twelve equals, that is to say, the twelve tones within an octave are divided into twelve equal parts, (the law of fifth symbiosis is not average) Well, the difference of 440 hertz between A1 and A2 is divided into 12 equal parts, which is the frequency of the 12 semitones within this octave.

The specific algorithm is as follows: a1=440

#a1=440+440×1\\12

b1=440+440×2\\12

c2=440+440×3\\12

#c2=440+440×4\\12

d2=440+440×5\\12

#d2=440+440×6\\12

e2=440+440×7\\12

f2=440+440×8\\12

#f2=440+440×9\\12

g2=440+440×10\\12

#g2=440+440×11\\12

a2=440+440×12\\12

The rest of the equation is extrapolated: the (a1) of the small character group to the (a) of the small character group is also an octave, then we know that a = 220, and the difference between a and a1 is 220 Hz, then the frequencies of the twelve keys within this octave are:

a=220#a=220+220×1\\12

b=220+220×2\\12

c1=220+220×3\\12

#c1=220+220×4\\12

The others are no longer typed one by one).

In this way, you can know all the frequencies of the 88 keys on the piano.

Then there's the lowest note on the piano, A2, which is hertz.

What is the frequency of a standard pitch of 8°?

The frequency of the nth bond of the formula is calculated as.
