Is the difference between a grand piano and an upright piano the shape?

The appearance is simple, the store is a standing, a lying down, this is just the difference in appearance, the biggest difference is the mechanical structure of the action and the keyboard. After striking the strings, the hammer needs to be returned to its original position in time for the next strike. Compared to an upright piano in which the hammer strikes the strings horizontally and returns to the original position by the force of the spring, the action of the hammer is more labor-saving after striking the strings from below and returning to the original position by its own weight.

Thus, the ability to combo a single key in an upright piano is 7 times in 1 second, and 14 times for a grand piano. It's a tactile difference.

The sound difference is that the volume of the upright piano and the grand piano is basically the same, but the sound of the triangle is richer, because the dynamic area between the very weak and the very strong is wider, the intensity of the sound is very distinct, and the performance is rich.

In addition, the soundboard of an upright piano is inside the body, and it is box-shaped, so there is always a feeling of being low. However, the soundboard of a grand piano is under a cast iron plate, and when the lid is opened, the sound will be strengthened, and the sound will immediately enter the ear, so it is easier to confirm each note when playing.

Therefore, the piano used to play will be triangular.

The structure is different and the size of the sounding device is different, so the timbre and ** are different.

The grand piano is good, but it is expensive, occupies a large area, and is laborious to carry, suitable for performances, and is placed in large places such as halls and large living rooms.

Upright piano** is cheaper than a grand piano of the same brand, occupies less space, and is suitable for general family space.

The tone is better on the triangle.

**Upright is cheap.

The size of the triangle is more occupied.

There are two main types of pianos, upright pianos and grand pianos. In most cases, a grand piano is used for professional performances and stage pianos, while upright pianos are used for personal home practice.

1. The mechanical structure of the action is different from that of the keyboard

1) The upright piano is struck by the hammer from the transverse strings, borrowing the power of the spring to return to the original position, the ability of a single key to hit the continuous is 7 seconds, and the frequency of repeated strikes of the hammer is much lower than that of the grand piano.

2) After the grand piano strikes the strings from below, it returns to its original position by its own weight for the next stroke, and the continuous hitting ability of a single key is 14 times in a second, and the action of the hammer is more labor-saving, and the sensitivity has also been greatly improved.

2. The sound is different:

1) The sound of the upright piano is slightly weak, because the soundboard is in the body, and it is box-shaped, so there is always a low feeling.

2) The sound of the grand piano is relatively richer, because its soundboard area is larger, and the soundboard is under the cast iron plate, as long as the lid is opened, the sound will be enhanced, and the sound will be played immediately into the ear, and it is easier to confirm each note when playing.

Advantages and disadvantages of a grand piano.

Pros: Long strings provide a full, balanced tone that adds to the ambiance that ** and *

Disadvantages: A good grand piano starts at about 200,000 yuan, which is expensive, takes up a lot of space, and is difficult to move.

Advantages and disadvantages of upright pianos.

Pros: Upright pianos are much cheaper than even the smallest grand pianos, and rapid depreciation can help you find a reasonable piano.

Disadvantages: Due to the position of the soundboard, the column is sensitive to temperature fluctuations; Sustain pedals are usually omitted on upright pianos, but this provides room for a "muted" pedal that reduces the volume.

Upright piano and grand piano are both more common piano styles in life, although I have seen it, but for non-professionals, I still don't know what is the difference between an upright piano and a grand piano. So which is better, an upright piano or a grand piano, and what is the difference between a tripod piano and a regular piano? Let's take a closer look.

Tripod piano and regular piano:

1. The principle of movement is different, the ordinary upright piano is equivalent to directly hitting the string from above, and returning to the original position through its own force, while the grand piano is struck from the transverse plane through the hammer, and then it needs to return to the original position with the help of the power of the spring, and the reaction time required for the grand piano is longer.

2. The volume and expressiveness are different, the sound of the grand piano is relatively richer and richer, and a variety of timbres can be obtained through contact with the keys, and the performance between extremely weak and extremely strong is more obvious; Ordinary pianos, on the other hand, have less timbre, and are a little weaker in terms of expressiveness and resonance.

3. The foot pedal is different, the left side of the grand piano is the shift pedal, while the ordinary piano is the soft pedal; The pedal in the middle part is a normal piano with a silencer pedal, and a tripod piano has a selective sustain pedal.

In fact, there is no absolute good or bad between upright piano and grand piano, this is still related to professionalism and quantity, if it is just from the piano, then the grand piano may be better.

There are two main types of pianos, one is called a platform piano grand piano, and the other is an upright piano. Grand pianos come in a variety of sizes, generally divided by the length of the body, including 9 feet, 7 feet, 5 feet, etc. Upright pianos are generally divided according to the height of the body, which is 121 cm, 123 cm, 125 cm, etc.

The general length, width and height of a grand piano are:9-foot grand piano size: 278*102*155cm7-foot grand piano size:

The differences between an upright piano and a grand piano are as follows:

1. There is a qualitative difference between the upright piano and the grand piano in the principle of movement.

This is also the case that many students who study piano usually practice upright piano, and it is difficult to adapt to playing the grand piano when they are on stage, and their fingers often lose control. An upright piano returns to its original position with the help of the force of a spring, while a grand piano is a hammer that needs to be returned to its original position in time after striking the strings.

One is mechanical and the other is naturally falling, which is like a big difference between the two pianos in terms of feel and key sensitivity. The ability to make a single key on an upright piano is 7 seconds and 14 seconds for a grand piano.

Second, it is the same three pedals, but the functions are different.

The sustain pedal on the right is consistent. The left-side pedal grand piano is a shift pedal, and the upright piano is a soft pedal, and their structure is completely different. The principle of an upright piano is to make the hammer struck close to the strings and soften the sound; The shift pedal of a grand piano allows the keys to move to the right as a whole, and the hammer that used to strike three strings can now be struck with two.

In this way, the vibrations generated between the played string and the resonant string are reversed and cancel each other out. In this way, not only the volume but also the timbre brings a subtle change; Pedals make a big difference. The ** pedal of an upright piano is a silenced pedal that reduces the overall volume if necessary.

The pedal of a grand piano is a selective sustain pedal, which only prolongs the tone when you press a key and then press the pedal.

3. There is a big difference between the volume and expressiveness of an upright piano and a grand piano.

The triangle sound is richer, the difference between very weak and very strong is obvious, and the grand piano can express a richer timbre by touching the keys with the fingers, and the overall sound quality is not the same due to the increase in the soundboard structure, string length and soundboard area.

1. Hand feel. The feel is mainly reflected by the sensitivity of the keys, which comes from the reaction speed of the hammer, and the reaction speed of the hammer depends on the quality of the action. Ordinary action is slow to respond, good action responds quickly, when the key is not fully lifted when playing, press the key again, the hammer of the hammer responds quickly, can immediately rebound and feedback to the key, the natural feel is better, this is not possible to achieve most upright pianos, individual upright pianos can reach this level, but it is also the top upright piano.

For grand piano, the hammer on the hammer is struck from the bottom to the top, and after the tapping, the hammer will naturally fall by this gravity, the strings will be faster, and the key rebound will feel better. According to the 2017 Guinness Book of World Records, the fastest time a grand piano can be struck at one second.

The upright piano is struck horizontally, and then it needs a spring to return it to its position, and then it is struck again according to the command of the lower key, and the speed of this spring is slower than that of the grand piano, but the frequency of the strings can also reach about 8 times per second.

If you are playing some professional repertoire and need a relatively fast tempo, the advantages of the grand piano are obvious.

2. Resonance. The resonance of the grand piano will be better than that of the upright piano, the most important thing is that the resonance cavity of the triangle is relatively large, the soundboard is transverse, and its sound is scattered, so the sound transmitted will be farther, and the volume of the cherry blossom is grander, and the sound quality is more pleasant. The upright piano is sounded through the soundboard of the façade behind it, and the upright piano is usually placed against the wall, so the sound waves are transmitted to the wall and then reflected to our ears.

At the same time, when the grand piano is played, it is generally played with the lid open, which is conducive to better transmitting the sound; When most people play the upright piano, the lid is played with the lid on, even if some people will hold up the top cover, but the pole is short, and it can only be opened, so the sound transmission effect is naturally not as good as that of the triangle.

3.It's the shell. In the early days, the shell of the top grand piano would use solid wood that was easy to resonate, so that the resonance effect was good, and the sound could be transmitted well through the shell.

But now you see that most upright pianos are almost made of MDF, and MDF can't do a good resonance, and the sound is naturally muffled in the piano. Of course, now you can hardly see the solid wood shell, wood is scarce, if there is also used in the grand piano, to play its greatest value.

Now you can imagine why the grand piano is basically used in the concert hall, because of its good resonance, the sound of the piano can be clearly heard in the entire theater hall, which is something that an upright piano can't do.
