What is the core of sketch?

Concept: 1 Sketch in a broad sense refers to all monochrome paintings; Sketch in a narrow sense refers to the painting training process used to learn art skills, explore modeling rules and cultivate professional habits. Art is a means to express things. The foundation of art is modeling, which is a complex labor carried out by people in a natural way and a special skill that needs long-term training. Artistic modeling is not only to shape isolated and static object forms, but more importantly, to express the organic relations of various forms in objects. To master the method of artistic modeling, we should not only restore people's natural way of thinking and operation, but also study the formal characteristics of natural objects and understand their changing laws and conditions. Sketch is the best way to solve these modeling problems, which has been fully proved in the practice of artistic modeling. Therefore, sketch is called "the foundation of plastic arts". 2. English sketch. Material: 3. Monochrome pictures of light and dark objects are drawn with charcoal, pencils, pens, etc. , also known as sketching. Sketch is the basis of all painting and a necessary stage in the research process. (Artist Magazine on Sketch-Xiao) 4. Sketch usually refers to methods that can leave traces on a plane, such as crayons, charcoal pens, pens, brushes, ink and paper, and others include the abrasion of wet clay, ink-stained cloth strips, metals, stone tools, containers or cloth surfaces. (Encyclopedia of Artistic Vision) 5. Outlines and lines are the general term for sketches. Sketch has a sense of natural law, which the viewer can feel from the process of appreciation. Different strokes create different lines and cross relationships, including rhythm, active and passive surroundings, plane, volume, tone and texture. 6. Sketch is a kind of formal artistic creation, which uses monochrome lines to express things in the intuitive world, and can also express ideas, concepts, attitudes, feelings, fantasies, symbols and even abstract forms. It does not pay attention to the whole and color like painting, but to the structure and form. Encyclopedia Britannica 7. In the book Dictionary of Western Fine Arts (published by Lion Book Company), there is only one explanation related to sketch. It is considered that the sketch of a work or a part of a work is the artist's research and discussion on key points such as light and shadow, composition and the scale of the whole picture; It is a preliminary composition of the whole painting or one of the paintings. The sketch of a landscape painter is usually a small and quick record to show the lighting effect of the landscape and prepare for the idea of repainting in the future. 8. Sketch is a kind of expression with lines and faces. Every object has three parts under illumination: light and dark. From the deepest to the brightest, it is the boundary between bright and dark, dark, reflective, gray and bright. Try to avoid bright parts and dark parts when painting (because there are too many lines, there is no gap and reflection). Sketch is the inevitable foundation of other arts, especially. Although sketch is considered as a two-dimensional art, it does not need color and three-dimensional space, but it also implies both. Learning: In the process of sketch practice, sketch must show the shape observed by one's eyes concretely and subtly with the help of the relationship between light and things and the brushwork. Therefore, sketch needs to cultivate its own observation ability. In addition, sketch can also be interpreted as all efforts between "being" and "painting", which is called "descriptive power of painting". For example, when depicting the still life on the table, we can not only find the different colors on the still life, but also find the harmony between the security on the table and the background. The complex factors such as shape, color, line, light and shade, texture, sense of quantity, sense of existence, sense of space and sense of dynamics are intertwined to form a beautiful order. Painting is to turn those natural orders into picturesque ones, which is also the meaning and purpose of sketch. Sketch is the basis of painting, and it is a kind of painting that can best reflect people's painting level. Therefore, we should be down-to-earth in our study, stick to it and not be impetuous. Sketch examination of college entrance examination for fine arts: With the development of higher education in China, the enrollment of fine arts colleges and majors is increasing, and many high school students who love fine arts apply for the examination. Sketch examination is the main subject of the examination for fine arts majors. How to improve the sketch score of college entrance examination is a problem that candidates are struggling to find. Therefore, the study of sketch examination is the top priority of art teachers' teaching in senior high schools. At the end of 19, European art completely liberated the description of three-dimensional form and color due to the different pursuit and discussion of the artistic essence of post-impressionism and cubism party, so it also changed the traditional sketch training mode. In some countries, such as the Fine Arts Department of the University of Paris I, France, the course of "Sketch" has been replaced by "Two-dimensional, Monochrome and Multicolor Research". In this course arrangement, there is more space for sketch and more flexible materials. Students can use all kinds of media to practice two-dimensional modeling at will. Therefore, in addition to the basic concept of sketch, we should give more flexibility and flexibility in the training of sketch media, so that the training of sketch can not only match the artistic trend of thought, but also show stronger vitality and wider expressive force. Sketch is an idea. It is also the basis of all graphic behaviors, especially painting. Up to now, sketch has been regarded as a special technique of expression, including line description, light and shadow, emphasis, tone and so on. Sketch refers to the basic expression in painting. Because the main modeling elements of painting are lines and colors, if you want to play an infinitely beautiful scene in a limited two-dimensional space, you must skillfully use modeling techniques to achieve arbitrary results. Therefore, sketch is a record made by a painter who observes, experiences, imagines, chooses and reorganizes beautiful ideas with the simplest tools. Because we focus on the process of painting development, there may be various tentative experiments, so the content and form of sketch expression are also diverse and rich. Sketch is not only the basis of learning painting, but a good sketch itself is an independent work of art. Because the tools it uses are relatively simple and the completion time is short, it often conveys the author's instantaneous inspiration and passion more directly than many processed paintings, and captures the vivid charm of the painted objects. In some excellent sketches, we can get intuitive artistic feelings that are not easy to appreciate in other paintings. In the history of western art, many masters of painting have left a lot of sketches, such as Three Renaissance Masters, Rubens, Rembrandt, Goya, Angel, Lie Bin and Menser. And some great painters, such as Titian and Velazquez, are rarely circulated, because they are good at drawing directly on canvas, so there are not many sketches left; However, from the few works we have seen, we can still see their unique skills in sketching.
