An example of a motif being central to a movement of work is in the third movement of Bach’s Brandenburg Concerto No. 5. The opening phrase - and excerpts from the phrase - can be heard throughout the movement.
Sequences were often used in Baroque melodies. This was one way composers made melodies longer. An example of a sequence can be found in the ground bass of Henry Purcell’s Music for a While. The four-quaver motif rises four times and is the foundation of this haunting piece of music.
Sequences can also be found in the first movement of Antonio Vivaldi’s Spring from The Four Seasons. At bar 48, the solo violin plays a virtuosic arpeggiated idea. This is repeated as an ascending sequence until it becomes a descending sequence starting in bar 53.
Imitation is commonly used in Baroque melodies, particularly because a lot of the music was fugal, ie written in the style of a fugue. The opening of the third movement of Bach’s Brandenburg Concerto No. 5 is a good example of this. Many of the choruses in Handel’s Messiah also contain examples of imitation, including “And the glory of the Lord” and “And he shall purify”.
Trills, mordents and turns were often used in Baroque melodies. These can be found in the solo violin part of the first movement of “Spring” from The Four Seasons by Vivaldi.
The development of equal temperament enabled the 12 major and minor keys to be established. This was the most significant thing to happen to the tonality of Baroque music.
The chords used in major and minor tonalities were also major or minor - or diatonic.
The use of ground bass was common in the Baroque period. Composers would use a ground bass to structure their music. They made the harmonies above the ground bass change, and the placement of the phrases also varied. One of the most well-known examples of a ground bass is in “Dido’s Lament”, from Henry Purcell’s Dido and Aeneas.
Henry Purcell’s Music for a while also contains a ground bass.
The passacaglia is a type of composition which contains a ground bass. Bach wrote many such pieces, particularly for organ. Listen to this example.
A number of forms were developed in the Renaissance and Baroque periods.
Structures in the Renaissance period were mainly based on the text being used. Religious music was written to be sung by choirs in churches. It often took the form of masses or motets. The congregation would not have sung at all. Outside the church, the madrigal was a popular song form and there were also many types of dance music, eg the galliard or the pavane.
Binary form has two sections. It was commonly used by Baroque composers - especially in dances. Binary form also followed some conventions in terms of tonality:
Ternary form is made up of three sections. It was commonly found in the minuet and trio in Baroque dances. It then evolved into a movement within the Classical symphony. The repeat of section A is not always exact, but is very close to the opening section.
In ritornello form, the section A returns between each new section. It was commonly used in the Baroque period. The ritornello section - A - would often return in keys related to the tonic, for example, the dominant or the relative minor. If the original section was long, it would often return in a shortened version. The sections between the ritornello sections are called episodes. Ritornello form evolved into rondo form in the Classical period. Ritornello form can be found in many concerti grossi, such as Johann Sebastian Bach’s Brandenburg Concertos.
This was a common form found in several types of vocal music including operas by composers such as George Frederick Handel and oratorios - perhaps the most famous is Handel’s Messiah. A da capo aria is one where the voice returns to the top of the movement (da capo) and repeats the first section of the music. It was common for the soloist to add ornamentation when the first section was repeated. “He was despised” from Handel’s Messiah is an example of a da capo aria.
A ground bass is a repeated bass line over which harmonies and melodies change. Ground bass was popular in Baroque music. An example can be found in Henry Purcell’s Music for a While or “Dido’s Lament” from Dido and Aeneas.
