I will just point out here the title of the third movement of the is quartet. It is “Heiliger Dankgesang eines Genesenen an die Gottheit, in der lydischen Tonart” (A holy song of thanksgiving of a convalescent to the Deity in the Lydian mode).
It is a remarkable movement, the longest of the quartet. There is more about the “Late Quartets” below. These are not easy pieces, but they are well worth listening to as they are the most profound works that Beethoven wrote.

Beethoven’s Late Quartets

Beethoven’s five late string quartets are often considered to be the greatest music of the greatest composer who ever lived. Or, put more grandly still, the greatest achievement in any medium of the greatest artist who ever lived.

Needless to say, this is not a universally held opinion. Even among composers, Bach and Mozart have their champions, and the high esteem in which Beethoven’s late quartets are now held is really only a phenomenon of the 20th century. For decades after Beethoven’s death in 1827, the late quartets were rarely performed, regarded widely as the eccentric, unlistenable products of a deaf and irascible genius. Indeed, the slowness with which they came to be appreciated may be the principal inspiration for all composers of difficult music since, those who cling to the hope that an enlightened posterity will recognize works that a cruel present ignores.

If the 19th century was puzzled by the intellectual density of these scores, our own time has not only embraced that density, but has seen through it to the touchingly direct expressions of emotion that underlie all of Beethoven’s music.

These late quartets, which occupied Beethoven in the final two and one half years of his life, have attracted the attention of music’s greatest analysts, from Sir Donald Tovey to Joseph Kerman and Charles Rosen in our own time. They have been perceived as signposts pointing back to Haydn and Mozart and forward to Wagner, Mahler and Webern; as a summa of technical exploration, and as the ultimate expression of Beethoven’s songfulness and emotionality.

Few of Beethoven’s contemporaries embraced the challenges of the late quartets; rather, it remained for the following generations to come to terms with them. Though traces of op. 130 did turn up as early as the finale of Schubert’s last piano sonata (1828), the quartets from the 1830s and 40s of Mendelssohn, his sister Fanny Hensel, and Robert Schumann were arguably among the first to attempt to absorb the idiosyncrasies of the late style. During the nineteenth century, none of Beethoven’s successors matched his output in the genre, though Dvořák was able to write fourteen; like Schumann, Brahms produced only three. Debussy, a “musicien français” who eschewed a reliance on Austro-Germanic traditions, wrote only one, though admittedly, it used cyclic thematic techniques between its movements that ultimately derived from Beethoven’s precedent. On the other hand, in the last century several composers wholeheartedly took up the question, posed by Schubert shortly before he died in 1828, as to what, if anything, was left for them to write after Beethoven’s op. 131.

In effect, Beethoven had upturned Goethe’s polite, rational conversation of equals: the string quartet genre now plumbed the interior world of the composer, the very depths of the human psyche, with all its unpredictability. The final phase for Beethoven was to enter the extraordinary and arguably irrational world of the five late quartets, op. 127, 132, and 130 (dedicated to Prince Gallitzin), together with op. 131 and 135 — all composed in short order, in 1825 and 1826. Here, in the final years of his life, the heart and mind of the composer worked in tandem to generate unprecedented music of searing autobiographical intensity and abstract compositional logic, pointing the way to a transcendental, romantic language of pure tones. It was the ultimate Beethovenian paradox. On the one hand, this was music of a deaf composer that called out for words (the expressive cavatina of op. 130; the “Sacred Song of Thanks of a Convalescent to the Deity in the Lydian Mode” as the interior midpoint of op. 132; and the sphinx-like “Difficult Decision,” for the finale of op. 135). On the other, the late quartets also tested musical logic by returning to the chess-like patterns and combinations of cerebral counterpoint (e.g., using a fugue to open op. 131; incorporating a chorale fugue in the “Sacred Song” of op. 132; and compiling a compendium of fugal artifices in the “Great Fugue,” so dissonant and ahead of its time that Stravinsky later celebrated it as a work of contemporary music).

Modernists endeavored to find answers. The Second Viennese School of Schoenberg, Berg, and Webern, while abandoning tonality, continued to cultivate the string quartet. The six quartets of the Hungarian Béla Bartók are now often regarded as constituting a cycle worthy of Beethoven, and several other modernists were conspicuously prolific in the genre, including Milhaud (eighteen, of which two were designed to be performed either as quartets or together as an octet), Shostakovich (fifteen), Elizabeth Maconchy (thirteen), Villa-Lobos (seventeen), and Peter Maxwell Davies (ten). In 1972, the American George Rochberg, a confirmed serialist and composer of seven quartets, committed a controversial volte-face by reviving tonal triads in his Third String Quartet, alluding in a neo-romantic idiom directly to Beethoven’s late quartets, as if to bridge the wide historical gulf separating Rochberg from the 1820s.

Ludwig van Beethoven
(c. 1770–1827)

Who Was Ludwig van Beethoven?
Ludwig van Beethoven was a German pianist and composer widely considered to be one of the greatest musical geniuses of all time. His innovative compositions combined vocals and instruments, widening the scope of sonata, symphony, concerto and quartet. He is the crucial transitional figure connecting the Classical and Romantic ages of Western music.

Beethoven’s personal life was marked by a struggle against deafness, and some of his most important works were composed during the last 10 years of his life, when he was quite unable to hear. He died at the age of 56.

Controversial Birthday
Beethoven was born on or about December 16, 1770, in the city of Bonn in the Electorate of Cologne, a principality of the Holy Roman Empire. Although his exact date of birth is uncertain, Beethoven was baptized on December 17, 1770.

As a matter of law and custom, babies at the time were baptized within 24 hours of birth, so December 16 is his most likely birthdate.

Family
Beethoven had two younger brothers who survived into adulthood: Caspar, born in 1774, and Johann, born in 1776. Beethoven’s mother, Maria Magdalena van Beethoven, was a slender, genteel, and deeply moralistic woman.

His father, Johann van Beethoven, was a mediocre court singer better known for his alcoholism than any musical ability. However, Beethoven’s grandfather, godfather and namesake, Kapellmeister Ludwig van Beethoven, was Bonn’s most prosperous and eminent musician, a source of endless pride for young Beethoven.

Childhood Abuse
Sometime between the births of his two younger brothers, Beethoven’s father began teaching him music with an extraordinary rigor and brutality that affected him for the rest of his life.

Neighbors provided accounts of the small boy weeping while he played the clavier, standing atop a footstool to reach the keys, his father beating him for each hesitation or mistake.

On a near daily basis, Beethoven was flogged, locked in the cellar and deprived of sleep for extra hours of practice. He studied the violin and clavier with his father as well as taking additional lessons from organists around town. Whether in spite of or because of his father’s draconian methods, Beethoven was a prodigiously talented musician from his earliest days.

Education
Hoping that his young son would be recognized as a musical prodigy à la Wolfgang Mozart, Beethoven’s father arranged his first public recital for March 26, 1778. Billed as a “little son of 6 years,” (Mozart’s age when he debuted for Empress Maria Theresia) although he was in fact 7, Beethoven played impressively, but his recital received no press whatsoever.

Meanwhile, the musical prodigy attended a Latin grade school named Tirocinium, where a classmate said, “Not a sign was to be discovered of that spark of genius which glowed so brilliantly in him afterwards.”

Beethoven, who struggled with sums and spelling his entire life, was at best an average student, and some biographers have hypothesized that he may have had mild dyslexia. As he put it himself, “Music comes to me more readily than words.”

In 1781, at the age of 10, Beethoven withdrew from school to study music full time with Christian Gottlob Neefe, the newly appointed Court Organist, and at the age of 12, Beethoven published his first composition, a set of piano variations on a theme by an obscure classical composer named Dressler.

By 1784, his alcoholism worsening and his voice decaying, Beethoven’s father was no longer able to support his family, and Beethoven formally requested an official appointment as Assistant Court Organist. Despite his youth, his request was accepted, and Beethoven was put on the court payroll with a modest annual salary of 150 florins.

Beethoven and Mozart
There is only speculation and inconclusive evidence that Beethoven ever met with Mozart, let alone studied with him. In an effort to facilitate his musical development, in 1787 the court sent Beethoven to Vienna, Europe’s capital of culture and music, where he hoped to study with Mozart.

Tradition has it that, upon hearing Beethoven, Mozart said, “Keep your eyes on him; someday he will give the world something to talk about.”

After only a few weeks in Vienna, Beethoven learned that his mother had fallen ill and he returned home to Bonn. Remaining there, Beethoven continued to carve out his reputation as the city’s most promising young court musician.

Early Career as a Composer
When the Holy Roman Emperor Joseph II died in 1790, a 19-year-old Beethoven received the immense honor of composing a musical memorial in his honor. For reasons that remain unclear, Beethoven’s composition was never performed, and most assumed the young musician had proven unequal to the task.

However, more than a century later, Johannes Brahms discovered that Beethoven had in fact composed a “beautiful and noble” piece of music entitled Cantata on the Death of Emperor Joseph II. It is now considered his earliest masterpiece.

Beethoven and Haydn
In 1792, with French revolutionary forces sweeping across the Rhineland into the Electorate of Cologne, Beethoven decided to leave his hometown for Vienna once again. Mozart had passed away a year earlier, leaving Joseph Haydn as the unquestioned greatest composer alive.

Haydn was living in Vienna at the time, and it was with Haydn that the young Beethoven now intended to study. As his friend and patron Count Waldstein wrote in a farewell letter, “Mozart’s genius mourns and weeps over the death of his disciple. It found refuge, but no release with the inexhaustible Haydn; through him, now, it seeks to unite with another. By means of assiduous labor you will receive the spirit of Mozart from the hands of Haydn.”

In Vienna, Beethoven dedicated himself wholeheartedly to musical study with the most eminent musicians of the age. He studied piano with Haydn, vocal composition with Antonio Salieri and counterpoint with Johann Albrechtsberger. Not yet known as a composer, Beethoven quickly established a reputation as a virtuoso pianist who was especially adept at improvisation.

Debut Performance
Beethoven won many patrons among the leading citizens of the Viennese aristocracy, who provided him with lodging and funds, allowing Beethoven, in 1794, to sever ties with the Electorate of Cologne. Beethoven made his long-awaited public debut in Vienna on March 29, 1795.

Although there is considerable debate over which of his early piano concerti he performed that night, most scholars believe he played what is known as his “first” piano concerto in C Major. Shortly thereafter, Beethoven decided to publish a series of three piano trios as his Opus 1, which were an enormous critical and financial success.

In the first spring of the new century, on April 2, 1800, Beethoven debuted his Symphony No. 1 in C major at the Royal Imperial Theater in Vienna. Although Beethoven would grow to detest the piece — “In those days I did not know how to compose,” he later remarked — the graceful and melodious symphony nevertheless established him as one of Europe’s most celebrated composers.

As the new century progressed, Beethoven composed piece after piece that marked him as a masterful composer reaching his musical maturity. His Six String Quartets, published in 1801, demonstrate complete mastery of that most difficult and cherished of Viennese forms developed by Mozart and Haydn.

Beethoven also composed The Creatures of Prometheus in 1801, a wildly popular ballet that received 27 performances at the Imperial Court Theater. It was around the same time that Beethoven discovered he was losing his hearing.

Personal Life
For a variety of reasons that included his crippling shyness and unfortunate physical appearance, Beethoven never married or had children. He was, however, desperately in love with a married woman named Antonie Brentano.

Over the course of two days in July of 1812, Beethoven wrote her a long and beautiful love letter that he never sent. Addressed “to you, my Immortal Beloved,” the letter said in part, “My heart is full of so many things to say to you — ah — there are moments when I feel that speech amounts to nothing at all — Cheer up — remain my true, my only love, my all as I am yours.”

The death of Beethoven’s brother Caspar in 1815 sparked one of the great trials of his life, a painful legal battle with his sister-in-law, Johanna, over the custody of Karl van Beethoven, his nephew and her son.

Despite his extraordinary output of beautiful music, Beethoven was lonely and frequently miserable throughout his adult life. Short-tempered, absent-minded, greedy and suspicious to the point of paranoia, Beethoven feuded with his brothers, his publishers, his housekeepers, his pupils and his patrons.

In one illustrative incident, Beethoven attempted to break a chair over the head of Prince Lichnowsky, one of his closest friends and most loyal patrons. Another time he stood in the doorway of Prince Lobkowitz’s palace shouting for all to hear, “Lobkowitz is a donkey!”

Was Beethoven Deaf?
At the same time as Beethoven was composing some of his most immortal works, he was struggling to come to terms with a shocking and terrible fact, one that he tried desperately to conceal: He was going deaf.

By the turn of the 19th century, Beethoven struggled to make out the words spoken to him in conversation.

Beethoven revealed in a heart-wrenching 1801 letter to his friend Franz Wegeler, “I must confess that I lead a miserable life. For almost two years I have ceased to attend any social functions, just because I find it impossible to say to people: I am deaf. If I had any other profession, I might be able to cope with my infirmity; but in my profession it is a terrible handicap.”

Heiligenstadt Testament
At times driven to extremes of melancholy by his affliction, Beethoven described his despair in a long and poignant note that he concealed his entire life.

Dated October 6, 1802, and referred to as “The Heiligenstadt Testament,” it reads in part: “O you men who think or say that I am malevolent, stubborn or misanthropic, how greatly do you wrong me. You do not know the secret cause which makes me seem that way to you and I would have ended my life — it was only my art that held me back. Ah, it seemed impossible to leave the world until I had brought forth all that I felt was within me.”

Almost miraculously, despite his rapidly progressing deafness, Beethoven continued to compose at a furious pace.

Moonlight Sonata
From 1803 to 1812, what is known as his “middle” or “heroic” period, he composed an opera, six symphonies, four solo concerti, five string quartets, six-string sonatas, seven piano sonatas, five sets of piano variations, four overtures, four trios, two sextets and 72 songs.

The most famous among these were the haunting Moonlight Sonata, symphonies No. 3-8, the Kreutzer violin sonata and Fidelio, his only opera.

In terms of the astonishing output of superlatively complex, original and beautiful music, this period in Beethoven’s life is unrivaled by any of any other composer in history.

Death
Beethoven died on March 26, 1827, at the age of 56, of cirrhosis of the liver.

The autopsy also provided clues to the origins of his deafness: While his quick temper, chronic diarrhea and deafness are consistent with arterial disease, a competing theory traces Beethoven’s deafness to contracting typhus in the summer of 1796.

Scientists analyzing a remaining fragment of Beethoven’s skull noticed high levels of lead and hypothesized lead poisoning as a potential cause of death, but that theory has been largely discredited.

Legacy
Beethoven is widely considered one of the greatest, if not the single greatest, composer of all time. Beethoven’s body of musical compositions stands with William Shakespeare’s plays at the outer limits of human brilliance.

And the fact Beethoven composed his most beautiful and extraordinary music while deaf is an almost superhuman feat of creative genius, perhaps only paralleled in the history of artistic achievement by John Milton writing Paradise Lost while blind.
