What does the role of induction in piano mean?

The introduction in piano means that the auxiliary key is the black key in the piano.

The word "induction" in piano means a key that starts playing in advance.

On a piano, two adjacent keys (including the black keys) form a semitone, and two notes separated by a key form a whole tone.

There is a "distance" between notes, and this distance is a relatively calculable value. In **, the minimum distance between two adjacent tones is called a semitone, and the two chromatic distances form a whole tone. In the case of a piano, the two keyboards that are closely connected on the piano keyboard form a semitone, and the two keyboards next to each other are the whole tone.

The 3rd and 4th tones and 7 harmonies at the white key position form semitones; The composition between 1 and 2, between 2 and 3, and between 4 and 7 is diatonic. There is a black key between 1 and 2, and 1 and 2 form a semitone with this black key.

Prelude. It also has the meaning of "order".

The twelve-average rate divides an octave into 13 tones (with one repeat), 8 cardinal tones (with one repeat), and 5 variations. The basic tones are arranged according to the C natural major tonality, and the variations do not appear in the C natural major. Therefore, in order to distinguish them, they are divided into two different colors, white for the basic sound and black for the variation.

Of course, the choice of black and white is completely easy to distinguish. Because there is no one who is so colorblind that they can't tell the difference between black and white. If you are not colorblind, you can also replace them with other colors.

Why black and white? Be.

In the piano, Yinjian is really not very clear, let's see what others say.

The piano keyboard is white.

Extended Information] The white key is the white key in the piano keyboard, which is placed downward, longer and wider. There are a total of 52 white keys out of the 88 keys in the piano keyboard, and 7 white keys in each set of 12 keys. The white keys can be used to play C natural major and A natural minor directly.

The black keys are the black keys in the piano keyboard, which are positioned upward, shorter, and narrower. There are a total of 36 black keys out of the 88 keys in the piano keyboard, and 5 black keys out of 12 keys in each group.

To put it simply, all keys on the piano (black and white) are keys, only the black key is at the back and the white key is at the front, and the designer separates the key in the key of C. As for why, refer to the music theory knowledge that wangshenghe13 said.

For those who learn to play the piano, there is probably nothing more important than mastering the keyboard of the piano. Intuitively, the keyboard of a piano is composed of a total of 88 keys of black and white keys (a few pianos only have 85 keys). Among them, there are 36 black keys and 52 white bonds.

If you look closely at the black and white keys, it is easy to see the regularity of their distribution and arrangement. i.e.: the black keys are in groups of two and three in groups.

Shown below are the notes of the piano's 88 keys and 52 white and 5 black keys.

From the keyboard, it is easy to see that the entire keyboard is basically composed of seven Arabic numeral tones located above the white keys of "**1(c)", "1 2 3 4 5 6 7". These seven Arabic numerals are also called musical notes. If we try to play the seven notes of ** in sequence (for now, we don't need to worry about the use of fingers), and try to sing each note in the way marked below:

1 Sing do 2 Sing re 3 Sing mi 4 Sing fa 5 Sing so 6 Sing la 7 Sing xi

After playing the "7" note (xi), and then play the "" sound with a red dot on it, you can realize that the "" tone with the dot on it feels the same as the sound of the **"1" tone, but the pitch is a little higher, which is the so-called "octave higher" sound. Similarly, the acoustic sensation of playing the "" note with a little bit on the left side of the **1" is similar to the sound of the "7" without dotting, which is both a "lower octave" note. This allows us to deduce the basic characteristics of the remaining notes with red dots on top and bottom.

Let's take a look at the white and black keys on the keyboard "**1(c)" circled in yellow with seven notes. The black keys repeat the symbols "b" and "". "b" is a falling chromatic horn and "" is a sharp chromatic horn.

They are all notes that define their bottom right. For example, "b2" means "flat 2", that is, "2" sound flat semitone; "1" means "1 sharp", that is, "1" sound rising semitone. The black keys can be marked by two notes:

For example, the black key between "1" and "2" can be represented by the two sounds "b2" and "1", i.e., "b2" = ".

In this diagram, only the black keys and their corresponding notes in the seven notes in the ** section are marked. I'm sure you'll be able to say the black key notes in no time other than **1.

How can you quickly remember these 88 keyboards and their corresponding notes? It is important to remember that the seven white key sounds marked "1 2 3 4 5 6 7" marked "**1(c)" circled in yellow. There are two things to keep in mind:

1) **"1" is located near the keyhole on the cover of the piano keyboard; The black key on the left side of the black key in a group of two is this **"1". In any case, this **"1" must be kept in mind. The other six notes are arranged in order to the right.

2) White keys and 1, there are no black keys between 3 and 4, and the remaining 1 and 2;2 and 3; 4 and 5; 5 and 6; There are black keys between 6 and 7.

Normally, a piano has 88 keys, including 52 white keys and 26 black keys, but sometimes that's the case, and some electronic keyboards are a little bit less

The piano has 88 keys....White 52 keys black 36 keys ...It is divided into high and low registers....

88, that's too simple.

Nothing is "empty" to put it bluntly. Actually, I still recommend that you learn staves. Because after all, staves are the most formal, buy a book to read, or ask a friend to help teach you how to read music. It's good to see it well.

No key, no key... Let's learn staves.

If you have taken piano lessons, the teacher has taught the piano**c, after **, you ask the child Lu Ruzi, which is **c, I think it can be explained to some extent, the child remembers what the teacher said, or can feel the ability to feel the keyboard, if you unconsciously press **c, in my opinion, it doesn't mean anything.

If the pen of God has not been used for a long time, it has suddenly found the feeling again, and the craftsmanship has been deserted for a long time, and now it is playing the piano again.

Anyway, I've only seen two-story electronic piano-like instruments, and then there's the pipe organ that has always appeared in theaters and churches, all of which are two-storey, and I think the one you're talking about is probably an organ, the piano is not like this, and even the harpsichord, the predecessor of the piano, has no two layers.

I don't know the number of keys, so you might as well check it out
