Calligraphy is a visual art related to writing. It is the design and execution of lettering with a broad tip instrument, dip pen, or brush, among other writing instruments. A contemporary calligraphic practice can be defined as, "the art of giving form to signs in an expressive, harmonious, and skillful manner".
Modern calligraphy ranges from functional inscriptions and designs to fine-art pieces where the letters may or may not be readable. Classical calligraphy differs from typography and non-classical hand-lettering, though a calligrapher may practice both.
Calligraphy continues to flourish in the forms of wedding and event invitations, font design and typography, original hand-lettered logo design, religious art, announcements, graphic design and commissioned calligraphic art, cut stone inscriptions, and memorial documents. It is also used for props and moving images for film and television, testimonials, birth and death certificates, maps, and other written works.
The principal tools for a calligrapher are the pen and the brush. Calligraphy pens write with nibs that may be flat, round, or pointed. For some decorative purposes, multi-nibbed pens—steel brushes—can be used. However, works have also been created with felt-tip and ballpoint pens, although these works do not employ angled lines.
In Chinese calligraphy, Chinese characters can be written according to five major styles. These styles are intrinsically linked to the history of Chinese script.
When used in decorative ornamentation, such as book covers, movie posters, and wall hangings, characters are often written in ancient variations or simplifications that deviate from the modern standards used in Chinese, Japanese, Vietnamese or Korean. Modern variations or simplifications of characters, akin to Chinese Simplified characters or Japanese shinjitai, are occasionally used, especially since some simplified forms derive from cursive script shapes in the first place.
The Japanese syllabaries of katakana and hiragana are used in calligraphy; the katakana were derived from the shapes of regular script characters and hiragana from those of cursive script. In Korea, the post-Korean War period saw the increased use of hangul, the Korean alphabet, in calligraphy.
The seal script (often called "small seal" script) is the formal script of the Qín system of writing, which evolved during the Eastern Zhōu dynasty in the state of Qín and was imposed as the standard in areas Qín gradually conquered. Although some modern calligraphers practice the most ancient oracle bone script as well as various other scripts older than seal script found on Zhōu dynasty bronze inscriptions, seal script is the oldest style that continues to be widely practiced.
