The development and history of violin almost cover contemporary physics during the same period  

When Newton was developing his classical mechanics to determine how planets move in the sky, Antonio? Stradivari created some of the world's greatest and most precious violins in Cremona, Italy.  

At that time, this instrument had evolved from the drum and zither about a hundred years ago and was made by another Italian manufacturer, Gasparro? Saro and his student Giovanni Maggini ultimately established its form  

A loud voice is needed to facilitate performance in the public. This purpose drove this evolution, just like the evolution of modern electric guitars.  

At that time, the violin was just a common instrument, quaint and crude. Gu Se has always been loved by the royal family.  

Saro's new design, by Andrea, another manufacturer from Cremona? Amati saw it and copied it, and then his son continued to refine the violin design in his father's direction.  

The question of whether Stradivari is an apprentice of Amati stems from the indication on one of his violins that the style is derived from Amati.

We can be certain that both of them lived in Cremona in the second half of the 17th century, and the violins that Stradivari began making were in the style of Amari.  

But he soon went his separate ways and began his long and glorious career. He made over a thousand musical instruments in his lifetime.

By 1750, the violin had gained widespread recognition.  

In fact, most of the most famous composers at that time had written works for this characteristic instrument.  

It was their demands that led to some final improvements to the violin. Increased pitch and lengthened the neck (and therefore the string length), allowing for a wider range of notes.  

Unfortunately, the original method of simply nailing and gluing the neck of the piano proved too weak to withstand the tension of the strings.  

In the late 18th century, the manufacturer Mantegaza developed a method of mortising the neck into the sides and top block to increase its strength.  

The modern violin was thus born.  

However, violins made over the next two hundred years failed to replicate the success of early Italian manufacturers, leading many to believe that one or more secrets had been lost in some way.  

However, during this period, progress was made in understanding how string instruments produce their unique sounds.  

German physicist Hermann? Feng? Helmholtz explained the motion of bowstring. Fixed length and tension, as well as continuous sound (periodicity), mean that the possible frequencies can only be integer multiples of the fundamental frequency (i.e. the lowest allowed vibration mode).  

In music, this means that for a given note, the octave above it, the fifth above it, another octave above it, the third above it, and so on, are all part of that sound.  

Helmholtz realized that the wood from which these violin sounds were made must have rich harmonics, and he was curious about how the vibrating strings produced these harmonics.
