A contemporary definition of calligraphic practice is "the art of giving form to signs in an expressive, harmonious and skillful manner." The story of writing is one of aesthetic development framed within the technical skills, transmission speed(s) and material limitations of a person, time and place.A style of writing is described as a script, hand or alphabet.Calligraphy ranges from functional hand-lettered inscriptions and designs to fine art pieces where the abstract expression of the handwritten mark may or may not supersede the legibility of the letters. Classical calligraphy differs from typography and non-classical hand-lettering, though a calligrapher may create all of these; characters are historically disciplined yet fluid and spontaneous, improvised at the moment of writing.
