Music historiographers classified the six periods of music in history of classical music. Classical period music history:
Before 1400 – Medieval music – characterized by the significant use of chant. It was later harmonized with 4ths, 5ths, and octaves. Many styles of music took form during the Medieval Period: Gregorian Chant, organum,motets, liturgical dramas, and chansons.
1400-1600 – Renaissance – Principal liturgical fomes were masses and motets, with some other developments towards the end, especially as composers of sacred music began to adopt secular forms (such as the madrigal) for their own designs.Common sacred genres were the mass, the motet, the madrigale spirituale, and the laude.
1600-1750 – Baroque music – characterized by the use of complex tonal counterpoint and the use of a basso continuo (continuous bass line). Music became more complex in comparison with the songs of earlier periods. The beginnings of the sonata form took shape in the canzona, as did a more formalized notion of theme and variations.
1750-1820 – Classical – The classical movement was going to bring the music ”down to earth”. Composers began to strive for beauty through simplicity and balance.
1820-1900 – Romantic – Romanticism seeks out the new, the curious, and the adventurous. It is characterized by restless seeking and impulsive reaction.The tiny piano piece and the brief lyrical song, forms which had been of no consequence during the Classical period, now assumed the highest significance. The moderate length of the classical symphony and opera was hugely extended (Mahler’s symphonies, Wagner’s operas). Romanticism cherishes freedom of expression, movement, passion, and endless pursuit of the unattainable (fantasy and imagination); a search for new subject matters.
Beyond 1900 – 20th Century – Also known as the Age of Technology, 20th Century Music took full advantage of new technologies as they became available. Not constricted by rules of the classical period, composers had the stylistic freedom to write however they pleased.
