The word "Baroque" is used in other art forms besides music: we talk about Baroque architecture, painting, sculpture, dance and literature. The Baroque period comes between the Renaissance and the period of Classicism (the Classical Period).
Musicians think of the Baroque period as starting around 1600. The famous Renaissance composers Palestrina and Lassus had died a few years earlier. Claudio Monteverdi wrote some music in Renaissance style, and other music in Baroque style. Opera was being invented. It was a time of musical change.
The change from writing music in the Baroque style to the Classical style was much more gradual. 1750 is the year that Bach died, so it is an easy date to choose for the end of the Baroque period.
The Baroque was a time when people liked large spaces and a lot of ornamentation. This can be seen in the architecture of famous buildings such as St. Peter's Basilica, Rome, or St. Paul’s Cathedral, London. They were built at this time. In Venice there were churches with galleries on either side of the church. Composers liked to write music for two groups of musicians placed in opposite galleries. Giovanni Gabrieli wrote a lot of music like this.
The idea of two contrasting groups was used a lot in Baroque music. Composers wrote concertos. These were pieces for orchestra and a solo instrument. Sometimes a concerto contrasted a group of soloists with the rest of the orchestra. These are called by the Italian name "Concerti Grossi. Bach’s Brandenburg Concertos are good examples.
Baroque music was often a melody with a bass line at the bottom. This could be, for example, a singer and a cello. There was also a harpsichord or organ that played the bass line as well, and made up chords in between. Often the composer did not bother to write out all the chords (harmonies) but just showed some of the chords by figures, leaving it to the performer to decide exactly which notes to play. This is called “figured bass” or “basso continuo”. The soloist, who played or sang the melody on top, often put in lots of ornamental notes. Again: the composer did not write this all down but left it to the performer to improvise something nice around the notes he had written.
Because composers were now writing opera it was important for the audience to hear the words clearly. In the Renaissance the groups of a choir were often singing several different words at once. This was called “polyphony”. It sounded beautiful, but was no good for opera which is telling a story.
When a soloist in an opera sings a song (an aria) the aria is in a particular mood. They called this “affection”. There were several “affections” or moods: there were arias about revenge, jealousy, anger, love, despair, peaceful happiness etc. Each movement in a concerto also had one particular mood. Music from later periods is different. For example: Haydn in the Classical Period would often change its mood during a piece.
Here are a few of the most important composers of the Baroque period:
