Maria Theresa of Paradis

from Wikipedia, the free encyclopedia
Maria Theresia Paradis, 1784.

Maria Theresia Paradis , often called by Paradis despite her bourgeois origin (born May 15, 1759 in Vienna , † February 1, 1824 in Vienna), was an Austrian pianist , singer (soprano), composer and music teacher . She has been blind from early childhood. She was very prominent in Viennese musical life and known to many important representatives of Viennese classical music such as Joseph Haydn and Wolfgang Amadeus Mozart . On a European tour from 1783 to 1786 she played in front of numerous high-ranking personalities, including the French royal couple Louis XVI. and Marie Antoinette and the English King George III. and his wife Charlotte . Valentin Haüy was so fascinated by her at a concert in 1784 that he began to campaign for the education of the blind.

Life

Maria Theresia Paradis was one of the daughters of the Viennese court official Joseph Anton Paradis and his wife Maria Rosalia. It was named after her sister Maria Theresia Clotildis (June 3, 1758 - March 17, 1759) who died before she was born. In addition to the twin sisters Josepha and Elisabeth, she had a few other sisters and brothers. Her grandfather Claudius was a valet and then “Countess Esterházy'scher Regent”, her uncle Leopold was a dancer who “went to Paris in 1753 to 'learn to dance better there' and in 1776 took over the ballet school of the Moscow orphanage”. When Maria Theresia Paradis was around three years old, she went blind. In addition to a good general education, she received music lessons from Viennese music greats such as Leopold Koželuh ( piano ), Vincenzo Righini , Abbé Georg Joseph Vogler ( vocals ) and Antonio Salieri ( harmony ), who was also part of the family's circle of friends for a long time.

Contrary to widespread claims going back to Franz Gräffer , “the Paradis” was not a godchild of Empress Maria Theresa , but received financial support, a so-called grace pension, from the empress's personal purse, which was later deleted by Joseph II . Since 1775 she was very prominent as a pianist in Vienna and gave numerous concerts.

Organ with original case from 1730 in the Augustinian Church in Vienna

In Vienna as well as on her major European tour, she performed many works by her main teacher Koželuh as well as piano concertos by Joseph Haydn (there is evidence of a concert in G major Hob XVIII: 4) and, more rarely, by Wolfgang Amadeus Mozart . In a letter dated February 16, 1785, Leopold Mozart wrote to his daughter Maria Anna about a new piano concerto that his son had "made for the Paradis in Paris". According to recent research, this is probably KV 456 . Salieri dedicated his 1773 Organ Concerto to her, which she most likely also performed in public. There is evidence that she played on the organ of the Augustinian Church in Vienna.

After being martyred by a multitude of treatments that were modern at the time, which were supposed to cure her blindness, she was considered incurable by the doctors recognized at the Viennese court. After that, she was a patient of the doctor Franz Anton Mesmer , who was famous in Vienna but who was hostile to him by colleagues, for a few months , after which her condition improved noticeably at times. After her parents withdrew Mesmer's treatment in June 1777, she reverted to total blindness. To what extent this blindness arose or what triggered it, is so far only speculated.

European tour

A major tour took the pianist from 1783 to 1786 to Hamburg, where she met Carl Philipp Emanuel Bach , Berlin, Switzerland, France, England, the Austrian Netherlands and Bohemia. She was accompanied by her mother Maria Rosalia and Sigmund Falgara (1752–1790, musician, at least until February 1784) and her librettist, violinist and later partner Johann Riedinger (presumably from autumn 1785), who invented braille notation because of her. Almost all concert descriptions from this time are similar:

“The Spiritual Concert of Easter 1st granted our Parisians a rare appearance. Mlle Paradis of Vienna, completely deprived of her eyesight from the second year of age, played the Klavecin and amazed us all. This blind virtuoso was the first to tear us out of the mistaken delusion that the Klavecin could not make any particular effect in a large and extensive sale: she proved the opposite with the strength of her playing, to general applause. The young person, who is so interesting by herself as by her talents, is a student of the famous Kozeluch . "

Maria Theresia Paradis toured Europe 1783–1786

Through this concert tour Maria Theresia Paradis became known beyond the borders of Austria and particularly impressed and influenced Valentin Haüy and Johann Wilhelm Klein , the founders of the first institutes for the blind in Paris , Vienna and Berlin . For her correspondence she used a type case developed by Wolfgang von Kempelen , her former tutor, a pre-form of the blind typewriter. This laid the foundation for today's Braille by Louis Braille . Her travel stops can also be documented using the logbook that she carried with her on the trip - and thus also several personalities who have entered it. Many musicians and composers traveled through Europe during this time, but mostly only in order to learn from their employers. B. to get to Italy and back for training. Maria Theresia Paradis' journey is - similar to the Mozart's child prodigy journey of 1763 - something extraordinary. Another blind contemporary of Maria Theresia Paradis, Marianne Kirchgeßner , was on tour almost all of her life. The logistics, the partly still poorly developed road system and above all the partly bad accommodations at that time presented a particular challenge.

Remarks

  1. Maria Theresia Paradis' travel destinations between Augsburg and Strasbourg have not been clarified: either she took the route via Stuttgart, Pforzheim and Rastatt or the southern route via Günzburg , Ulm , Ehingen , Donaueschingen , Villingen and Offenburg .
  2. Her route from Bern to Paris is also still uncertain: she may have traveled via Friborg , Lausanne , Geneva and Lyon .
  3. The way back from Calais to Brussels is also still unclear. A number of stops and travel stations on the way are as yet unknown or not yet explored further.

Composer

Maria Theresia Paradis had already started composing piano music and songs before her three-year concert tour, which mainly carried her reputation as a pianist around the world. During her trip, she wrote her Twelve Songs , the printing costs of which were reimbursed by Luise Eleonore von Sachsen-Meiningen , an enthusiastic sponsor. After her return, Maria Theresia Paradis devoted herself more intensively to composition in Vienna. Another important contributor to her advancement was her pen pal Sophie von La Roche . Later planned concert tours to Italy and Russia did not materialize. In addition to songs, Paradis composed melodrama, cantatas, chamber music, piano concertos, singspiels and operas. Little of it has been researched so far, as these compositions are largely only known from performance dates and contemporary reviews. Her singing plays and operas, which she wrote in the 1790s and which were premiered in the Theater am Kärntnertor , met with approval.

Music teacher

She was one of the co-initiators of the institution royale des jeunes aveugles ("Royal Institute for the Young Blind") founded by Valentin Haüy in Paris in 1784 . In 1808 she founded the "Schab den Rüssel" apartment in Rothenturmstrasse CN. 482 opened an institute for musical education in Vienna , where she taught piano, singing and music theory to blind and sighted girls and young women. This was made possible by a sheet music case specially made for them, with which music could be made comprehensible:

“She has small cards on which cut-out notes in their true form are stuck. (...) Now she lets the children recognize these notes (since they are raised on the cards, they are as familiar to her as the written ones) and in order to make the value of them fully understandable, she plays with them; she gives z. B. a whole note, and the value of the same can be given gradually in halves, quarters, etc. for it, on other sheets it has the whole scale of the violin and the bass; (...) In order to learn fluency in playing and the fingering soon, she gives them runs and certain passages through all keys, (...) to be sure that they use the right fingers everywhere, including the hands hold beautifully, your hand always hovers lightly over it. Since her zeal, her diligence and indefatigability are tireless, she achieves the beautiful purpose of building a school which one day will get its reputation and be appreciated. ”“ Indeed, they [the pupils] are all more sisterly To love, and all hang on with all their souls to their mistress, from whom they never receive a bad word, but only love. "

“School” here - apart from their apartment as the place of instruction for their students - means their own system, similar to Leopold Mozart's attempt at a thorough violin school (1756), which is still used today as a standard work in violin lessons. Your school or music institute was also a model for other institutes of this kind, such as B. for the blind pianist and composer Josef Proksch .

Salonnière

Several times a year Maria Theresia Paradis held successful and popular concerts, balls and festivities in her house, which offered local as well as well-known musicians who were traveling through a platform and were so much appreciated by the public that the local newspapers reported about them regularly. With these concerts she was up to date, the concert programs have been preserved. Politically, Maria Theresia Paradis saw herself on the side of the monarchy. In Paris she had also met the royal family and made music with Marie Antoinette personally in Versailles , who herself was an excellent pianist and composed. Maria Theresia Paradis' patriotism is expressed in her composition Auf die Damen, who instead of gold pluck canvas for the wounded warriors (1794). She represented enlightened views and had friendly relationships with other salonniers in Vienna such as Caroline Pichler and the writer Gabriele von Baumberg . In 1797 Paradis traveled to Prague for the last time to watch the premiere of her magic opera Rinaldo and Alcina in the Estates Theater , which was unsuccessful. Physically and mentally exhausted, she tried to relax in the nearby Karlovy Vary and took relaxing walks in the vicinity.

Retirement

Probably in October 1797 she returned to Vienna, got her music salon going again and was able to welcome Joseph Haydn as a guest there, who rehearsed his great work The Creation with Ignaz Franz von Mosel and with her at the piano :

“The blind master learned the 1st pianoforte by heart in an incredibly short time, the 2nd played the famous Abbot Vogler, solo and choral parts were performed by amateurs. So it was given in front of a large audience and in the presence of Haydn, who at the end hugged me with the assurance that he had never enjoyed his work so perfectly as in this form. "

A "lung addiction and added nerve fever" is said to have been Maria Theresia Paradis' cause of death. She bequeathed more debts than fortunes to Johann Riedinger - the poor institute in Vienna and some relatives and friends were left with some money. Riedinger, whose success waned more and more, was forced to sell Paradis' estate. Your Joseph Brodmann wing is thought to be lost. She was buried in the Sankt Marxer Friedhof , the grave is lost.

Works (selection)

Many of the numerous works by Maria Theresia Paradis have been lost. In her stage works, the influence of her teacher Salieri is particularly evident in the dramatic scenes, otherwise the typical “Viennese Singspiel tone” prevails. Her piano works are strongly influenced by the style of her teacher Koželuh.

reception

From the inventory of the Wien Museum, magazine. In need of restoration, without original glass cover. Real hair. Coming from a school for the blind in Vienna.

The Paradisgasse in the 19th district of Vienna Döbling was named after her.

In recognition of their work, the “Von Parádis Trio” was founded in Vienna in 1999 by the musicians Ursula Bosch, Ildikó Tarmann and Karin Hopferwieser. The from and the accent in the name of this trio are, however, erroneous curiosities, since Paradis was not aristocratic, her grandfather Claude Paradis came from Savoy and her name is thus emphasized on the last syllable.

Alissa Walser's novel In the Beginning was the Night Music revolves around Franz Anton Mesmer's efforts to heal Maria Theresia Paradis. Based on this novel, the film Licht (also Mademoiselle Paradis ) by Barbara Albert was made in 2017 with Maria Dragus in the role of Maria Theresia Paradis and Devid Striesow as Franz Anton Mesmer.

In the magazine of the Wien Museum (Biographical Collections) in Vienna there is a wax bust with real hair, glass eyes and a frilled robe, which according to the original plaque in the base represents Maria Theresia Paradis. This bust cannot be seen in the reference collection because it needs restoration and the original glass cover is missing. She was originally in a Viennese school for the blind, possibly as a memorandum and out of admiration for her personality as a (blind) music teacher and role model. This bust is the only life-size, preserved and previously known wax bust of an artist from this period.
