During the beginning of the
Baroque Era, the Renaissance forms continued to dominate the musical world.
During the second half of the century, there were distinct changes, as new
musical forms appeared.
Fugal Forms
The early
fugal forms were carried over from the Renaissance Era. They included the
fantasia,
canzona
(which was the forerunner precursor of the sonata), and the capriccio. These
were all written for keyboard instruments. By the mid 1600’s, these forms
were replaced by the
fugue.
The Fugue of the 1600’s was
monothematic.
Each voice stated the theme. The subject was played in the
tonic
key and answered in the dominant key. Fugues were
composed for all media, including choral ensembles. They were also written
as independent pieces and as movements in larger works.
Variation Forms
Thematic
variations
were used in various forms such as
cantus
firmus, canzona, and dance suites. Keyboard
instruments mainly carried out these variation forms.
Ground, which was a type of variation used
in England, had a short recurrent theme in the bass line and a continually
changing
counterpoint>.
Improvised variations on a ground are called divisions. Variations were also
called passacaglia and chaconne. Cantus firmus variations were important in
Germany. They restated the chorale melody completely and had a different
contrapuntal setting each time.
Dance Suite
Dance music
retained its importance from past musical eras. Suites or partitas were the
main dance forms. Harpsichords, chamber ensembles, and orchestras all played
dance music. There was no standard number or order for the movements in the
suites, and usually the movements were in the same key.
The form for each dance movement was
binary, meaning it had two sections that were repeated. The first section
modulated to the dominant key and the second section began in a contrasting
key and then moved back to tonic key at the conclusion.
Common dance movements that were specific
to the Baroque Era were the
courante,
gigue,
allemande,
and sarabande. Every now and then, other forms of nondance movements
appeared in suites such as airs, fugues, and variations.
Chorale Prelude
This was
the most important category of Baroque organ music and was used primarily in
church music. The
cantus
firmus was the most common chorale prelude. It had
longer note values and a fast moving counterpoint. The cantus firmus could
show up in any part of the piece. Sometimes it would appear in the pedels,
while at other times each phrase of the chorale would appear in imitative
counterpoint preceding the cantus firmus in longer notes.
A coloration chorale stated the chorale
melody in the top part as a cantus firmus and disguised the original melody
by using ornamention.
The
chorale
partita was a set of variations on a chorale tune.
Each variation was called a verse. The chorale melody was modified but
otherwise kept intact as cantus firmus. Only the accompanying counterpoint
changed.
Improvisatory
Forms
Certain keyboard forms such
as the
prelude,
fantasia, and
toccata
appeared regularly during the Baroque Era. There were no specific rules for
these improvisatory forms. They shared some common items such as
contrapuntal
textures, rapid scales, sustained chords, and figuration. Improvisation
lacked distinct thematic material and formal unity.
Sonata
The
sonata
was a multi-movement work that was composed for various solo instruments and
for small chamber groups during the Baroque era. The term sonata appeared in
the early 1500s in Italy. There were three types of sonatas: an
unaccompanied solo sonata that was written for the violoin or cello; an
accompanied solo sonata that was written for different instruments with
basso continuo; and a trio sonata that was written for two solo instruments
and basso continuo played by a keyboard instrument or cello.
The church sonata evolved in Italy after
1650. It had a number of movements that contrasted in tempo and texture. By
the end of the Baroque Era, church sonatas were written in four movements.
The tempo of the movements followed a slow-fast-slow-fast plan. They were
meant to be played in parts of a church service and used the organ to
perform the continuo parts.
The chamber sonata or sonata da camera was
a suite of dance movements. They were named corrente, giga, sarabanda, and
allemanda. Harpsichords were used to play the continuo in a chamber sonata.
By the late Baroque era, there were few distinctions between church and
chamber sonatas. They both included dance names for some movements and only
had tempo indications on some of the sonatas.
Tower
sonatas or
turmsonaten
were composed for a small group of wind instruments. They were meant to be
played at certain times of the day from church steeples or towers.
Keyboard sonatas were solo sonatas for the
harpsichord and appeared at the end of the 1600s. These sonatas represented
a very small percentage of Baroque instrumental compositions.
