Feature of Romantic



The romantic music has been influenced from the idea of romanticism. Romanticism extended to Europe in the latter half of the 19th century in the middle of the 18th century. The thought has extended the philosophy, literature, musical, and others. Classicism to the contrary, feelings, individuality, freedom, and others were esteemed and the mystical experience and the yearning for infinite were expressed.

In music, the Classical music has been developed based on romanticism. A lot of piano pieces were made because it was freely expressible. Moreover, the traditional music expression was used while pursuing new music. Therefore, it was a goal at the harmony of old and new.

 

The Early Part of Romantic


Musicians who were belonging exclusively of the court and the church started becoming independent, and it becoming a free artist. A literary element was taken into music. The pursuit of a richer expression started from the music of the form valuing. Groping for new harmony started, too.

The title was applied to the instrumental music tune, and "Program music" was born. The pioneer of the program music has two people, Ludwing van Beethoven and Hector Berlioz. Beethoven named the sixth symphony in F major key "Country". Berlioz were in music some themes, and composed "Der Freischutz" that was music with the story. A lot of program music were seen in the piano piece. It is this age that Frederic Francois Chopin who was called a piano poet was born. It is said by Berlioz that it established the program music in the symphony.

The opera also faced the heyday from a literary relation in the romantic age. At the same time, a regional characteristic became remarkable, and the work that reflected a racial taste arose. "Der Freischutz" in Germany and "Grand opera" in France is a typical music.

 

The Latter Period of Romantic


The musician in the latter period of romantic valued own principle and insistence. "Symphonic poem" in a new field was born as a result of pursuing a novel expression. This was made by the Franz Liszt. It was influenced from "Der Freischutz" of Berlioz who was his friend. The symphonic poem is not an orchestral music work of a single movement with "Title" but poetry by orchestral music. Liszt took up "Epic" as poetry.

The new music style that was called "Nationalist School" was able to be completed in the underdeveloped country of music. Nationalist School is nationalism music. It thinks mainly about politics and the culture by thinking about our race. And, it is called nationalism to request sense of values. The feature of Nationalist School is to use a peculiar music style of the folkloric music and the folk song of the home country. Therefore, the music of each country of various styles is completed.

 

 

In this age, there were a lot of music in which composer's individuality and regional were reflected. Moreover, a new concept that it was like Nationalist School, too.

Thus, the romantic music heralded the modern music. And, it has developed into the modern music.

Feature of Baroque


 The baroque music was active in the 18th century from the 17th century. The feature of the music at this time was that a gorgeous opera had become active.


 


 Vocal music was a center of music in the old days. However, the instrumental music tune has increased because the performances of musical instruments have gone up when becoming a baroque age. Therefore, various musical instruments have been developed. Musical instruments that had been often used were the recorders, viola de gamba[1], and cembalos. The improvement was added also as for musical instruments that were before. The cembalo is musical instruments that became it in a present piano. The color of the cembalo keyboard is opposite to the piano. However, it went out of use because neither the recorder, viola de gamba nor the cembalo had the room for the improvement when changing at the classical period in the baroque age.

 It is a baroque age that the opera that was the play music arose. The opera was made in Italy. The opera is the performing art that synthesizes literature, the play, the art, and music.


 In the first, it tried to manage to reproduce the play in a Greek age. People were not satisfactory in a chorus of a multi voice alone. Then, it thought the music of the form of accompaniment with musical instruments to be a soloist. However, a Greek play was not researched in detail at that time. It was presented, and it was read aloud, and however, the opera was born though it did not know whether to have been sung the birth very of a Greek play while researching.

 "Euridice" called the first opera was born by Girolamo May who is research music, Rinuccini who is poet, and Peri and Caccini who is composer.

 As for this opera, the harpsichord, the lute, and viola de gamba were used. Afterwards, monte Verdi built the base of the opera. He composed "Orfeo" in 1606. After, the opera has extended to Venice, Rome, and Naples.

 

 As the instrumental music tune developed, it was necessary to match conditions of musical instruments. The rule to adjust pitches of each musical instrument was made. It is a tuning method that is called "Temperament". Andreas Werckmeister establishes this rule. And Johann Sebastian Bach wrote "The Well-Tempered Clavier", and he made this rule known.

 There are "Major key" and "Minor key" in the tonality. The concern for harmony has risen. The music scale of major key and the minor key was considered to be a discord. However, it has been gradually standardized in the baroque age. In around 1680, Johann Pachelbel composed "Canon", and it became an example.

 

 The comparison between the melody and the bass was very valued in this age. It is called a thorough bass to mark the figure that shows harmony, and to supplement and to perform harmony with the keyboard and others improvising.

 

 There are musical historically two important things in the baroque age. The first was born the play music. The second was that instrumental music rises. Thus, the baroque music was constructed.

 

[1]The volumes are smaller than violins. Musical instruments are supported by the leg and played.

Performance Form


Today, I want to tell the orchestra and the solo as the performance form.

Orchestra


・Orchestra playing-Nutcracker-Pas de deux- (4:46)
 http://www.youtube.com/watch?v=kG0jMkoKLJo

 The orchestra came into existence from the instrumental music ensemble in around 1650. It consists of the musical instrument group named the stringed instrument, the woodwind, the brass instrument, and the percussion instrument. Moreover, there is a leader who generalizes the whole. It is Intendant to generalize the orchestra as the organization. Let’s see the organization of the orchestra with the performance.
  It is Kapellmeister, Musikdirektor, and Concertmaster to generalize the orchestra in music. Kapellmeister is a person in charge on the music side of the entire court band that matches the singer to the musical instrument performance. Concertmaster is a facilitator as the organization of the musical instrument performance. Moreover, the orchestra is pulled while performing in most cases by the player of the stringed instrument (especially, violin).
 The orchestra uses various musical instruments. Kinds of the musical instruments have changed. It is possible to read it from records of the past. It introduces typical musical instruments.
 

Violin



 There is putting the best bowstring in the violin respectively. The bowstring of strength that is appropriate for the size of the violin is put. The sound shuts oneself up when the bowstring is too fat. When the bowstring is too thin, it becomes a weak sound. It can be said that musical instruments will have been changed considering the volume, too. The violinist supports the violin firmly by the jaw and the left hand. Therefore, the movement of the position is not easy. It is necessary to raise the left hand when becoming loud tones. The violinist often performs at a high position in the orchestra work. The violinist has acquired such a technology.

 The bow changed the performing technique of the violin. It changed from a so-called baroque bow into Flachbogen. The tension of the bow doubled. The violin is added the improvement, and arrives now afterwards.
 

Flute



 In the 18th century, the recorder and the flute were concurrently used. However, the flute came to be used gradually in the orchestra because tone quality has been improved by a technical improvement of the flute. The compass of the flute became three octaves by the 18th end of the century. The role in the orchestra of the flute was solo and a concertino. However, so as not to be buried in other musical instruments of the orchestra, the flute has been improved. In the middle of 19th century, it came to be able to put out the compass of four octaves by using a key with the lid. And, the flute became musical instruments indispensable for the orchestra.

 

Oboe




 In the 18th first half of the century, the oboe was the typical woodwind in the orchestra. The role of the oboe is to play the melody with the violin besides solo. The performance ability of the oboe was almost the same as the violin in around 1700. When the upper register was performed because of a weak sound, the advanced technique was necessary for the oboist. Therefore, the composer did not write dynamic marks of “p” in the part of the oboe.


 In addition to this, there are trumpet of the brass instrument, tympani of the percussion instrument and others as musical instruments that compose the orchestra.
 

Solo


 
 Solo is said the alone performance while the orchestra performs a lot. Piano solo and the violin solo are the solo performances. Moreover, it is called solo to perform a certain part alone in the orchestra.

Piano Piece


  I will introduce "Nocturne op.9-2" and "Piano sonata K.331" from the piano piece. It is both tunes that everyone has heard somewhere.




Nocturne op.9-2


 This music was composed by Frederic Francois Chopin. This music was made in 1832, when Chopin was 22 years old.

  
  Chopin made 21 nocturnes. Only 20 in that were specified for “Nocturne” by him. However, only the C sharp minor of existing music in 1830 was allowed the title as “Nocturne” at the time of making in 1875 public.

  
   Nocturne op.9-2 is the most famous music in his nocturne. This music undertook other composer’s influences with Nocturne op.9-1.

  
  The composition of this music is a rondo style form. This music is 12/8 rhythms in Andante[1] in E flat major.


 A-B-A-B-A-C-C


There are two themes of A and B, and it is repeated alternately. There finishes is different theme C at the end. The right hand chants from beginning to end the coloratura style[2] to attaching of the grace note, and the accompaniment of the same rhythm is repeated as for the left hand.





Piano Sonata K.331


 This tune was composed by Wolfgang Amadeus Mozart. The made time is not understood well. There is a theory of composition in Paris at 1778, when Mozart was 22 years old or a theory of composition in Vienna at 1783, when he was 28 years old. The powerful one is a theory composed in 1783. This music is the second of three sonatas assumed to have been made in the age. This music consists of three movements. The rough composition is as follows.

  
  The first movement consists of the subject and the variations of andante grazioso. The second movement is a minuet of the trio luck. It is recorded though the third movement is an allegretto, "Rondo alla turca". The style of the east style at that time is remarkable.


  The first movements are 6/8 rhythms in A major. It consists of the subject and the variation. The subject of andante grazioso is two composition in the first half and the latter half. It was graceful though was simple. The style at this time is reflected. In the first variation, the movement of the sixteenth note[3] is a center. As for the second variation, the accompaniment of three group notes[4] feature. The third variation is transposed to the in A minor. The fourth variation returns to the in A major. The accompaniment is played by the right hand, and the high pitched sound part and the basso are played by the left hand. As for the fifth variation, it not only accompanies but also the tempo begins to change into the Adagio[1], and to move in the right hand three minims. The sixth variation becomes 4/4 rhythms Allegro[1]. It becomes a light, bright variation.

  
 The second movements are 3/4 rhythms in A minor in the minuet. The large-scale trio is lucky. The subject of the minuet starts by the unison of solo. The trio transposes in D major. The left hand intersects with the right hand, and has inserted the unison.

  
 The third movements are 2/4 rhythms in A minor in the Allegretto[1] (rondo alla turca). This is said, "Turkish march". The form of this movement is assumed to be a France style rondo. The famous subject appears the in A minor. The episode of the in A major starts after this part is repeated. Next, Passage of the sixteenth note continues. It is ended that the episode of the in A minor reproduces it after that. Next, it returns to in A minor again, and the main subject is repeated. In addition, it transposes to the in A major key. It is a colorful and outlandishness movement.







[1] It is a music term that shows the speed. Adagio means "It is gradual". Andante means "Speed where it walks". Allegretto means "It is a little fast". Allegro means "It is fast".

[2] Syllable that gives decoration to fast phrase, and makes colorfully.

[3] Length of 1/16 of whole note.

[4] Generic name of note with length in which a certain note is divided into three.








Form of Music
 

It can enjoy the musical expression by understanding the music form of music. As for the music that seems to be made freely, the music form that is basic is used for foundation. There are a lot of forms in the music. I will introduce the rondo form and the sonata form in music form.







Rondo Form




It is what became popular in France in about the 18th century. The rondo form is approved on the assumption of the alternation though it paired.


The basic format is A-B-A-C-A-D. This is called a chain rondo. The type of the rondo form of the music in the classical period is A-B-A-C-A-B-A. As for the rondo form as the music form, the change has been often added. It has the key role in compare in addition to a different structure setting the boundary between musical parts. To conclude the entire music, a musical each part is often enlarged.


Moreover, the conclusion of music is independent as a so called coda, becomes a musical part that reaches comparatively widely to greater or lesser degrees, and is gotten.





Sonata Form




The comparison of two subjects that are the tension of the subject, and contrasted structures and the character are an impellent of the music passage. The array of a time element in a double subject and the array of the material have brought the composer the possibility of music in the classical period expression. The sonata form is a form chiefly used for the first movement of the sonata form. This form might be called "Sonata allegro form" because it is performed at a fast tempo. 

The sonata form is used for all of a piano sonata in the classicism age, the string quartet, the symphony, and the concerto. Two subjects of contrasted character are used in the form of a sonata. It is thought that the sonata form has developed from the church sonata in the baroque age. It is originally assumed that it developed from two forms though it is three forms in the appearance.



The sonata form consists of three parts.


   Presentation part Presentation of subject

   Development part Laborious work based on motive and subject materials

   Reproduction part Return of subject


The presentation part starts by presenting the first subject. The passage part where the second subject is prepared comes out when the first subject is presented. The second subject has the character in contrast to the first subject. As for the passage part, the transposition to the dominant key is included. The conclusion part follows the passage part, and the presentation part ends. This might be repeated.


The motive and the component of the presentation part are being freely processed to the middle paragraph by the composer. The comparison between the first subject and the second subject is lost though the reproduction part is a repetition of the presentation part. To often do a connection taking musical, a harmony detour is done to a temporary transposition. To shut the entire music, the place in the presentation part where it is a conclusion part is enhanced.
