The shape and structure of the French horn:
The shape of the French horn appears as a thin copper tube. After being bent and coiled, it gradually A widened brass instrument, its basic shape is a thinner brass tube from the mouthpiece to the middle part of the French horn. As the winding is completed, the brass tube gradually becomes wider, forming the shape of a French horn. In addition to the basic shape of the French horn, the structure of the French horn also plays a decisive role in painting performance. The main structure of the French horn is divided into three parts: the mouthpiece, the tube body and the machine. The tube body gradually becomes wider after being bent and coiled, forming the existing visual effect.
French horn expression methods:
As a relatively special wind instrument, the French horn can be expressed in many ways, including sketch expression methods, color expression methods, and simple sketch expression methods. A number of painting expression forms, and in the introduction of this chapter, I mainly give a brief introduction to the simple expression method of the French horn. The simple representation method of the French horn specifically includes the following steps: The first step of the representation method is the conventional composition positioning. In this step, the painter is required to reasonably arrange the position of the French horn in the picture. The second step in the expression method is to use a lighter (such as charcoal strip) pen to draw the large outer shape and main structure of the French horn. The third step of the expression method is to use the simple method to formally sketch the French horn. The correct way to express it is as follows: start with the mouthpiece of the French horn, and then draw the middle curved part of the French horn and its mechanical key part. When expressing this part, pay attention to the interspersed changes of the copper tube and the front and rear of the copper tube. hierarchical relationship. After the first two are drawn, draw the mouth of the French horn. The mouth of the French horn is in the shape of a trumpet, and it should be drawn with a visual effect of wide left and right and narrow top and bottom.
