What are the types of pianos***?

I. From a historical point of view there are ancient pianos and modern pianos. And ancient pianos include:

1. Plucked-string ancient piano

Plucked-string ancient piano - Harpsichord (Harpsichord) in the sound source and the form of performance of these two characteristics, and strumming the ancient piano has exactly the same characteristics. The appearance is also basically the same, and even today we only from the appearance of the piano is difficult to distinguish which kind of piano they are. The two kinds of old pianos are the same in appearance, sound source and performance characteristics, but the sound effect they produce is completely different. This is due to the difference in the way the strings are excited. Plucked-string old piano is equipped with a plucking device at the end of the keyboard, and the plucks of the strings are made of leather wrapped in thin metal sheets, and the plumes of birds are also used as the plucks, which is why they are also known as the harpsichord. By pressing the keys and plucking the strings, the ten fingers can be used simultaneously to play various sounds and polyphonic music. This way of stimulating the strings has its own insurmountable drawbacks. First of all, the pizzicato method makes it difficult to change the volume and timbre, and it is impossible to overcome the pizzicato noise generated when the strings are pizzicato. And because the time the plectrum stays on the strings cannot be as short as the time the mallet stays on the strings (0.3 seconds), the strings cannot vibrate sufficiently and the sound is weak and short. These shortcomings determine its lack of musical expression. However, its slender and rhythmic tone has its own unique features, in the ancient court chamber music as a representative of the prevalence of music forms, this unique sound quality has an irreplaceable function, and its ability to be in the stage of music history in the scenery for 300 years to prove it.

2. The Clavichord

The Clavichord, or strummed ancient piano, is closer to the modern piano in terms of its sound source, the form in which it is played, and the way in which the strings are stimulated. However, its structure is too simple, there is no three-stage lever transmission; there is no device to detach the strings immediately after striking the strings; it cannot be played quickly and continuously; and there is no "soft and hard" mallet in the modern piano. The above four aspects are the main characteristics of the modern piano strummer keyboard. Due to the above reasons, the volume of the strummed ancient piano is small and slender, with a kind of quiet metallic tone, somewhat like the sound characteristics of the strummed steel piano, which also has its own fascinating sound. In a small range of chamber music works have other instruments difficult to replace the sound effect, and even in 1709 after the introduction of modern piano is still active in the European music scene for more than 100 years. With the continuous improvement of the modern piano, the fast pace of social life and the emergence of jazz, rock and roll needs, the ancient piano - like a soft, delicate and shy noblewoman - can only be relegated to the modern social stage after the curtain. Since the 19th century, the end of Europe and the rise of the retro wind, Europe's large and medium-sized cities well-preserved brilliant ancient architectural communities, the Renaissance literature, art, music ...... and other classical culture and art long vitality to make the ancient piano and then again with the dress, on the stage. This is exactly what we human beings in the rapid progress of the road to look back and found that should not be discarded valuable wealth. So the music of the Baroque period is played again, and the ancient piano has opened a new chapter. It is true that it does not occupy the mainstream of the modern music scene, but we believe that it will add the beauty of the evening sun to our spiritual life. These ancient cultural heritage should not be abandoned, of course, because it not only adds to our lives the magnificent beauty of the sunset, so that we can see the culture created by the forefathers of mankind, but also we are more sober to see the abundance of modern musical instruments, modern musical instruments of the king of the piano, at that time, such as the splendor of the day.

Two, from the use of the piano and appearance, divided into according to the shape of the different, can be divided into the platform type of grand piano and upright piano two.

Three, from the number of keys on the 88-key, 85-key piano
