Why is the rib wood in the high register of the piano denser

As explained earlier, the effect of strings on the timbre is now designed to improve the elasticity and hardness of the soundboard. At the same time, it quickly transmits sound waves to the entire soundboard, which is arranged diagonally with the wood texture of the strings from the low, midrange to the treble. The grain direction of the rib wood is arranged perpendicular to the soundboard and strings, so that the grain of the wood forms a horizontal and vertical intersecting network, so that the sound can be quickly transmitted throughout the soundboard at any point of the strings.

The rib is cut in diameter to improve the elasticity of the soundboard and strengthen the hardness of the soundboard. The curvature of the low surface of the rib makes it bond to the soundboard, so that one side of the soundboard rises with a certain curvature. The ends of the ribs are cut into tapering shapes to make the soundboard more vibrating.

The rib wood acts as an arched beam on the back of the soundboard (corresponding to the strings), which supports the pressure of the strings. The stress at the ends of the rib decreases, so it is cut into a duckbill shape to reduce the elasticity of the soundboard to avoid the rib ends being lifted. In the process of bonding the ribs to the soundboard, the vast majority of designers thread the ends of the ribs under the soundboard sideboard and the still-angled beams (openings).

Most of the ends of the strings are arranged on the ribs to enhance the elasticity of the soundboard, otherwise the sound quality will be affected to a certain extent. The firmness of the rib and the soundboard has a great impact on the timbre of the piano, the moisture content of the rib is too high before the glue, and the water dispersion loss after the glue connection with the soundboard will reduce the arc of the soundboard and the timbre deteriorate.

Generally, the ribs in the bass area are loosely arranged to make the low-frequency sound easy to propagate, while the spacing in the high-frequency area is smaller to enhance the ability of audio propagation. Ribs are an important part of the soundboard system, and the selection of rib wood, the size of the cross-section, the distribution of the curvature of the low surface in the soundboard, and the degree of solidity with the soundboard have a great impact on the timbre.

Not all pianos are like this, and some pianos have dense treble ribs because of the shape of the soundboard! Because the soundboard needs to be glued to the ribs and tightened to form an arc, the soundboard is elastic and easy to warp, and the soundboard in the treble area is narrower and has a greater force to warp, so it needs to be encrypted.

Because the soundboard is bonded together with solid wood, the rib strip plays the role of connecting the soundboard, reinforcing the soundboard, and preventing the soundboard from deforming and cracking.

Mine too, all with the sound of springs, trembling !!

It's not normal, ask the tuner to show you.

It's time to tune the piano, how long has it been?

Don't forget to step on the double-muted pedal, and those felts will be blocked between the hammer head and the wire, which has achieved the effect of muting

The piano also has a time to kill chickens, for fear that the blood test will stain your face.

In the whole range of the piano: the large character group, the large character group and the large character group 2 belong to the low register; The small character group, the small character group 1 and the small character group 2 belong to the middle range; The three groups of small characters, the four groups of small characters, and the five groups of small characters belong to the treble zone.

The pitch in the piano is usually divided into three parts: low, middle 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.

Each key on the piano keyboard corresponds to a tone, and all notes are arranged from low to high, from left to right, which is easy to identify at a glance.

An 88-key piano is generally divided into three registers:

1.Bass range: from A in the leftmost group of large characters on the piano to B in large groups (with 27 black and white keys);

2.Midrange: C in the small character group to F sharp in the small character group 2 (there are 31 black and white keys in total);

3.Treble area: G in the second group of small characters to C in the fifth group of small characters (a total of 30 black and white keys);

The highest note of the piano is C8, in order of pitch: C3, C2, C1.

The piano has a total of 88 keys, of which there are 8 Cs, **C is C4, and the last C is also the last key of the piano is C8, which is also the highest note of the piano.

A set of scales is C, D, E, F, G, A, B.

Among the 88 keys, 52 are white and 36 are black.

The white keys are used to play the basic scales, and are placed lower, longer, and wider. The white keys can be used to play C natural major and A natural minor directly.

Whereas, the black keys are used to play the variable scales, and the position is higher, shorter, and narrower. There are 5 black keys in each set of 12 keys.

Give you a picture and you'll understand. 7, 5, these are different ways of recording.

According to the American way, the highest note of the piano is C8, not the Shenma G 7 at all (what the hell is this moth = = I have seen similar statements that Maria Kelly sings the highest note is G7 = = or G7 = =

In the European way, the highest note of the piano is C5.

C8 and C5 both refer to a single tone. It's just that the saying is different, in Europe, the middle starts with a group of small characters, and the left is a large group, so there are only 5 groups to the right. In the United States, it has been pulled from the big character to the small character 5, so there is a c8 = = so that the so-called g7 is actually g4.

As for HB, it's upstairs.

The highest note of the piano is not G 7, but C8

Because the C closest to the middle of the keyboard is **C, which is also called C4, and moves to the right, the C higher than it is C5 and C6 respectively (refer to Stephen Kusterka and Dorothy Payne's "Overview of Tonal Harmony and the 20th Century" - Chapter 1 - Pitch Elements) and so on, and the rightmost note of the piano, that is, the highest note, is C8

Some people say that it is C5, which is based on the grouping of sounds, with C to B in a sound area as a group, the group starting from **C is called a group of small characters, and the order of an octave higher than it is: two groups of small characters, three groups of small characters, and so on. The highest note on the piano is the C of the small character group of five, so it is written as C 5 (refer to Zhao Xiaoping's "Basic Music Theory Tutorial" - Chapter 1, Section 6 - Grouping of Tones, the correct notation of this 5 should be displayed in the upper right corner like a power).

The highest note of the piano is C5, not C5, which refers to the C sound of the small character 5 group, in fact, the small character 5 group is also this one note. I really can't understand what the G 7 sound you wrote.

The highest note of the piano is the small character five group C

HighB is the B of the second group of small characters, two octaves lower than the highest note of the piano.

The pitch arrangement of all pianos is the same, and there is no random change.

I think I've heard of this kind of piano, but I haven't actually seen it, designed for left-handers?

I really don't understand such a question!
