In Western music history the term 'Classical' means the time between ca. 1760 and 1820. The period of the Viennese trinity Joseph Haydn, Wolfgang- Amadeus Mozart and Ludwig van Beethoven.
The term 'classic' came in vogue after Beethoven's death (1827) and denotes the perfection of form structure, the humanitarian continence and aesthetic ideals. One can freely translate 'classical' by adapting virtues as "truth, beauty, symmetry and harmony" as well as simplicity and clarity.
