A simplified answer is just this - a style in Western Music played between 1600 and 1750, the year when J.S.Bach died. His death marked the end of the baroque era. Of course, this does not explain much, but it's a start.
To better understand what kind of music it was (and is), one should know what was before and what came after. Although you will read about it in a different article, it is good to note that baroque period was preceeded by music of the Renaissance and followed by classical music style. And what a difference!
Let's start with the instruments. They were very different. Baroque composers inherited from Rennaissance a large variety of instruments which were still evolving and gradually gained prominence or became obsolete. In the beginning of the Baroque era we would see musicians in the prchestra playing instruments which will not appear at the time when J. S. Bach was old. The slideshow above the article is a collection of the instruments used during Baroque time and before. You see a mosaic of unfamiliar instruments of viol family, variously sized recorders, several types of keyboards. And practically no piano! It was invented in the 18th century and few works were composed for the piano by baroque composers. The king of large keyboard form was harpsicohrd, while virginals and clavichords were suited better for intimate chamber settings.
Recorders were gradually chased away by flutes, and a whole universe of strings narrowed down to several familiar instruments: violin, viola, cello, guitar... Very popular viola da gamba (a kind of cello with frets), many stringed viola d'amore occupy their place now in historical orhestras. Harpsichord, a keyboard instrument where strings are plucked and not struck by a hammer, very gentle but quiet clavichord and very small virginals were conquered by the piano at the beginning of classical time.blogging zelda blogging groups near me wordpress not blog but website blog before myspace blogging under pseudonym blog till the cat blogging through wordpress blog over 60 blogging etiquette blogging routine blogging prompts blogging vs youtube blog disney how to layout a blog blogging sites for free blogging niches considerations before blogging blogging vs vlogging blog icon blog xiaomi bloggingpro reviews blog of salt blog generator name blogging unscramble blog through google blog post title generator blog roblox blog underneath their robes blog before mario blog contra el amor inside outside blog blog difference between vlog blog to beyond blog blog xbox blog as a communication tool blog through the gaps blogging from the heart blogging without domain blog during spanish period blogging websites blog maker what really lies at the bottom of the ocean blog sign up blog zanquetta blogging pro blogging like apps blogging wrap up blogging on linkedin blogging to promote your business blog of holding blog pro 2.0 template blog xbox blog out of the box blog length blog sign off examples blogging with notion blogging essential tools blog inside shopify blog of oa blog from scratch blog for writers blogging jobs online blogging with google sites blog synonym blog synonym blog with video blog by sophia lee blogging without writing blog as subdomain or subdirectory blogging light what is blog made of abrogated what after blogging blogging like site blog writing examples what is blog made of blog contra bolsonaro
