[[UsefulNotes/DichterAndDenker German composer and virtuoso organist]] (21 March 1685 28 July 1750) whose works represent the culmination of the Baroque era and whose death is generally considered to mark the point of transition into the Classical era. Bach, [[Music/WolfgangAmadeusMozart Mozart]], and [[Music/LudwigVanBeethoven Beethoven]] are seen as the three main contenders for "Most Sublime Music in Western History," and not without reason.

Bach was the most prominent member of an extended family of musicians (it was often said of he, his wife, and his children that he could form an orchestra with them all). Though today he is considered one of the most influential composers in history, in his lifetime he was better known as an organist than a composer; particularly towards the end of his career, his work was deemed outdated by his contemporaries. He was generally not seen as one of the great composers until his works were re-popularized by composer Music/FelixMendelssohn in the early 1800s, and has since been VindicatedByHistory.

Noted in particular for his masterful use of contrapunctal technique, Bach's oeuvre consists of well over a thousand works. Some of the more well-known ones are:
* ''Music/ToccataAndFugueInDMinor'', BWV 565, the opening of which has become a StandardSnippet for OminousPipeOrgan moments. [[http://www.youtube.com/watch?v=_FXoyr_FyFw Here]]'s the whole thing played on the most awesome pipe organ in Australia.[[note]]However, there has been some debate as to whether he wrote the piece at all; it has a number of stylistic anachronisms that suggest it may have been written after 1750. Another school of thought holds that it may have been originally written for violin (possibly by Bach but likely by another unknown composer), and then transcribed to organ by Bach.[[/note]]
* ''The Well-Tempered Clavier'', two sets of twenty-four preludes and fugues, a prelude-and-fugue in every key in each set. The very first prelude, in C major, is [[http://www.youtube.com/watch?v=0KQW2YnCUrE something you might recognize]].
* The ''Mass in B minor'' and the ''St. Matthew Passion'', two breathtaking works that are cornerstones of Western sacred choral music.
* The six ''Brandenburg Concertos'', used widely in period dramas and various other works. The [[http://www.youtube.com/watch?v=vMSwVf_69Hc#t=1m26s harpsichord solo from the fifth concerto]] could quite reasonably be considered the great-great-great-grandfather of metal. The second, with its high, treacherous trumpet part (played in Bach's day [[http://www.youtube.com/watch?v=CEJ-xcblCMo on a ''valveless'' instrument]], no less) is the first piece of Earth music aliens will hear should they manage to acquire and decipher one of the [[http://en.wikipedia.org/wiki/Voyager_golden_record Voyager golden records]].
** Some suggested having ''only'' Bach on the record; Creator/CarlSagan said "that would just be showing off."
* The ''Air on the G String,'' the colloquial title given to the 2nd movement of Bach's Suite No. 3 in D major, BWV 1068. Even if you don't follow classical music, and don't know Bach from Bono, it's a certainty you've heard it many times as background music in movies, TV shows, and commercials. A strong contender for "Most Sublimely Beautiful 5 Minutes of Music Ever Composed."
* The ''Six Suites for Unaccompanied Cello'' are some of the most widely known cello pieces ever. The [[https://youtu.be/mGQLXRTl3Z0?t=9 prelude to the first suite]] is the best known from them. Pretty good considering there isn't even an original copy.
* ''Pieces From The Little Notebook'' is a book of piano (originally harpsichord) pieces, written for his second wife Anna Magdalena. They are some of the more popular works used to introduce piano students to classical (not Classical) music as a whole, due to their relative simplicity. (Like the Toccata and Fugue, the attribution of many of them to Bach is dubious.)

In addition, Bach's church gig at Leipzig's ''Thomaskirche '' required him to perform a sacred cantata on every Sunday and feast day of the Lutheran calendar. He composed at least three complete yearly cycles of cantatas -- over 300 works (1/3 of which, alas, are lost). The variety of form and style, mastery of polyphonic vocal writing, and breadth of instrumental tone color found in these works were unrivaled by his contemporaries.

Despite Bach's virtuosity and deep spirituality he was also refreshingly human. He was once rebuked for stretching a brief leave of absence into several ''months'' without apology or explanation. He often battled his employers over the duties and responsibilities of his position. He once wrote a cantata about a man's concern over his daughter's consumption of coffee ([[MustHaveCaffeine he was for it]], by the way). Then there is the wonderful story of Bach drawing his sword in an altercation with an instrumentalist that he had insulted, calling him a "nanny-goat bassoonist."

Interestingly, Bach shares not only a year of birth with Music/GeorgeFredericHandel (who was born a mere 37 days before Bach), but also a possible cause of death: they were both unsuccessfully operated on by the same eye surgeon -- an "oculist" called the Chevalier John Taylor, often referred to as "the poster child for 18th century medical quackery."

!!Tropes present in Bach's works:
* TheAce: UsefulNotes/FrederickTheGreat gave Bach a tricky chromatic theme and challenged him to [[ImpossibleTask improvise a fugue on it]]. Bach obliged. Frederick asked if Bach could [[MovingTheGoalposts improvise a three-part fugue]] using the same theme, knowing that Bach probably couldn't. Bach did. Frederick asked if he could [[WithThisHerring improvise a six-part fugue]] on the theme. Bach replied, in effect, "Leave it with me", and after tweaking the theme to make it easier to work with, wrote exactly that and sent it to Frederick, along with a bunch of other pieces based on the same theme. The collection is known as the ''Musical Offering'' and it's regarded as one of Bach's greatest achievements.
* BaroqueMusic: One of the most famous composers of this era. Many people claim the genre died out with him too.
* {{Cantata}}: Composed a lot of them.
* ChristmasSongs: The ''Christmas Oratorio'' and several cantatas intended for Christmas Day; "Jesu, Joy of Man's Desiring" is sometimes used like this.
* DeadArtistsAreBetter: Bach was better known as an organist than a composer during his lifetime. It was only when Music/FelixMendelssohn rediscovered his compositions in the 1800s that Bach became widely known as "[[TropeCodifier The Father of]] ClassicalMusic."
* DawnOfAnEra: 1685, the year J.S. Bach was born, is widely held to be the year when tonality in music (as we know it today) was found its footing, thanks to Archangelo Corelli. 1750, the year J.S. Bach died, is widely held to be the year when the Baroque period in music history ended and the Classical period began.
* GodIsLoveSongs: Being a devout Lutheran who was mostly employed by churches, he wrote a lot of religious pieces for church performance, among them the ''Johannes Passion'', ''Matthäus Passion'', the ''Mass in B Minor'' and, most spectacularly, over 300 sacred cantatas, of which about 200 survive. These include many of his most famous pieces, such as "Jesu Bleibet Meine Freude" ("Jesu, Joy of Man's Desiring"), which is a chorale from cantata BWV 147 ''Herz und Mund und Tat und Leben''.[[note]]"BWV" stands for Bach-Werke-Verzeichnis, the standard catalogue of Bach's complete works.[[/note]] This trope is averted inasmuch as Bach's cantatas aren't ''disguised'' as secular works; they're completely up-front about their religious content -- sample titles (translated) include ''Christ lay in Death's bonds'', ''God's time is the best time of all'' and ''Praise the Lord, the mighty king of honour''.
* LastNoteNightmare: "Great" Fugue in G minor (BWV 542) is quite soft and quiet for its first half. In the second half, the piece shifts toward being slightly more upbeat and louder, but still not too loud. Then at the very end, the piece shifts toward being loud and angry for a few seconds, contrasting with the light and soft qualities of the rest of the piece.
** Quite a few of Bach's organ fugues end this way. Apparently, Bach ''loved'' using the Picardy third.
** Perhaps Bach's most jarring example comes from the deceptively peaceful Adagio in C Major (BWV 564). Not only is the Adagio not actually positive-sounding, as its name would suggest, it has a short but incredibly aggressive ending portion that can only be described as OminousPipeOrgan taken UpToEleven. And, of course, the last chord is a Picardy Third. [[http://www.youtube.com/watch?v=YRV_vFrWq-o Listen here.]]
* MundaneMadeAwesome and MustHaveCaffeine:
** ''Schweigt stille, plaudert nicht'', AKA "The Coffee Cantata", where the entire plot is driven by coffee.
** ''The Art of Fugue'' is literally this trope, taking a simple subject and crafting fourteen fugues and four canons from it, in increasing complexity, to show the contrapuntal possibilities that could arise from a single theme.
* NonIndicativeName: Unlike every other prelude in the collection of preludes and fugues known as ''The Well-Tempered Clavier'', the Prelude in E flat major BWV 852 from Book 1 is actually a fugue.
* OminousPipeOrgan: His ''Toccata and Fugue in D minor'' has become a cliché of Halloween music, when played on a organ.
* OvershadowedByAwesome: A strange case. From Bach's death until his music's rediscovery, historians and musicians considered his sons' accomplishments more noteworthy than his; [[Music/WolfgangAmadeusMozart Mozart]] said of Bach's second son C.P.E. Bach, "He is the father, we are the children." This was historically justified, in that Bach's sons were considered to be more innovative and experimental than their father. Things changed when composers decided that they wanted some of that [[OlderIsBetter old-school contrapuntal wizardry]] that Bach had, but which his sons weren't interested in.
* PassionPlay: The ''St. Matthew Passion,'' of course, and also a lesser-known Passion from John's gospel.
* SignatureStyle: The fugue. Not everything he wrote was in fugue form but he clearly loved them; his last, great, unfinished work is a collection of them, all originating with variations on the same basic theme, called ''The Art of Fugue''.
* StrictlyFormula: Necessary, but subverted: he had to compose a new church cantata just about every week for three years, but within the canatata form they vary enormously in mood and tone, and Bach scholars tend to consider his cantatas to be the foundation of his achievement.
* SincerestFormOfFlattery: Name any great composer of ClassicalMusic. Odds are that, at some point in their education, they studied from and imitated the works of J.S. Bach. Bach's fugues and chorales are still required studying in most music conservatories to this day.
* TropeCodifier: He didn't invent the fugue, but boy, did he codify it (see SignatureStyle, above). Given that he could improvise three-part fugues on request, this is not surprising. Some musicologists argue that his music goes some way towards codifying Western harmonic music in general.

!! Bach in popular culture
* ''Music/{{PDQ Bach}}'' owns his artist's name to Bach. [[LiteraryAgentHypothesis The story goes]] that P.D.Q. was the 21st and least well-regarded of Bach's 20 children, disowned by the Bach family because his music was too stupid.
* ''Disney/{{Fantasia}}'' starts off with "Toccata And Fugue In D. Minor", which, true to the music's fashion is a series of abstract images.
** ''WesternAnimation/IlEtaitUneFois... L' Homme'' started off with "Toccata And Fugue In D. Minor" as its theme music.
** The basis for the ''VideoGame/{{Gyruss}}'' theme song.
** "[[http://www.youtube.com/watch?v=l9OFZ9Mh7GA Bach onto This]]" could even count as a {{Homage}}.
** A VideoGame/{{Touhou}} [[http://www.youtube.com/watch?v=Nfvo-xyq_zQ music arrange]] for Kanako Yasaka's theme, Suwa Foughten Field, begins with the opening.
** "Golbez, Clad in Darkness" from VideoGame/FinalFantasyIV quotes it as well.
** Eurobeat Brony's "Discord" uses the Fugue for its intro.
* Music/WendyCarlos made a career out of covering Bach's music in ElectronicMusic, starting off with ''Music/SwitchedOnBach''.
* Apollo 100's song "Joy" is a rock version of "Jesu, The Joy Of Man's Desiring."
** Music/TheByrds' song "She Don't Care About Time" has a guitar solo based on "Jesu, The Joy Of Man's Desiring".
** Music/{{Muse}}'s "Plug-in Baby" starts off with the opening of "Toccata And Fugue in D Minor".
** Music/TheKinks' "Wicked Annabella" briefly quotes "Jesu, The Joy Of Man's Desiring" in a bass fill.
* Sweetbox's ''Everything's Gonna Be Alright'' is based around ''Air on the G String'', from Bach's Orchestral Suite No.3.
* Live versions of ''Heartbreaker'' by Music/LedZeppelin often include a snippet of Bach's ''Bourrée in E minor''.
* Music/{{Megadeth}}'s ''Symphony Of Destruction'' has a piece of Mozart's ''Requiem (K. 626) - Domine Jesu Christe'' at the start. Also ''Last Rites'', based on Music/JohannSebastianBach's ''Toccata and Fugue in D minor'' (BWV 565).
* ''Repent Walpurgis'' by Music/ProcolHarum contains an excerpt of Music/JohannSebastianBach's ''Prelude No. 1 in C major'' (BWV 846).
** Music/ProcolHarum's greatest hit was ''A Whiter Shade of Pale'' - based on Bach's ''Air on the G String''
* Music/SymphonyX samples, among other pieces, Bach's "Mass in B Minor" in "Divine Wings of Tragedy". Further on the album "V-The New Mythology Suite" we also hear excerpts from Bach's ''Concerto for Harpsichord in D minor'' (BWV 1052) and the cantata ''Ich habe meine Zuversicht'' (BWV 188).
* Fitting the subject of the song, {{Music/Sakanaction}}'s "Bach no Senritsu o Yoru ni Kiita Sei Desu" ("Because Of Listening To Bach Melodies At Night") includes a short Bach snippet played on the piano.
* Bach has a cameo appearance in ''WebVideo/EpicRapBattlesOfHistory'' during the duel between Music/JustinBieber and Music/LudwigVanBeethoven.
* ''[[Anime/NeonGenesisEvangelion The End of Evangelion]]'' features both "Air" and a LonelyPianoPiece version of "Jesu, The Joy Of Man's Desiring" in its soundtrack. "Air" is even one of the titles for the first half of the film.
