Johann Sebastian Bach
The Well-Tempered Clavier Book I
Fugue No. 16 in G minor BWV 861 (arr. Förster)
If you have ever happened to see one of those cooking shows in which a chef is challenged to create an entire meal—appetizer, entrée and dessert—out of a minimum of ingredients (an ox-tail, say, and a banana) then you are well on your way to understanding the recipe for cooking up a Baroque fugue.
The aim of a fugue is to create an entire polyphonic composition out of only two melodies, either stated in their entirety or broken up into bits and pieces. These two melodies—the fugue’s subject and countersubject—are presented first in staggered entries, in the manner of a round. The subject enters first alone before being accompanied in subsequent entries by the countersubject. And then it’s off to the races in an alternating pattern of entries (where the subject is stated whole) and episodes (in which the bits and pieces are chewed over), roaming around in different keys. Somewhere near the end there is usually a stretto section, in which the conversation gets so lively that one voice can hardly get started before another voice interrupts to say the same thing, much in the manner of lively Italian dinner conversation.
Cleverness and ingenuity are built into the DNA of fugue-writing and Bach certainly did not stint on either in the construction of his Fugue in G minor from Book I of The Well-Tempered Clavier (1722). Witness the manner in which Bach constructs his fugue subject in two contrasting parts: a first part with semitone steps on either side of a downward-leaping minor 6th, then a second part comprised of a few notes running up and down in smooth stepwise motion. The countersubject (here is the cunning bit) is the same, but in reverse order and inverted: a few notes running down and up followed by a variant of an upward-leaping minor 6th motive. Bach’s subject generates its own countersubject—in the mirror!
The odd thing about this four-voice fugue is that the texture only rarely features all four voices playing at once—likely in order to make the dramatic leap of a minor 6th stand out more easily in a work written for keyboard. German composer Alban Förster (1849-1916), who arranged this fugue for string quartet, might have other ideas, however, about leaving one member of a quartet filing his nails while the others do all the heavy lifting.
Felix Mendelssohn
Quartet No. 2 in A minor Op. 13
Mendelssohn was not your typical Romantic-era composer. The polished grace of his melodies and clear formal outlines of his musical structures show him to have had one foot in the Classical era of Mozart and Haydn, while his penchant for imitative counterpoint and fugal writing shows that even that foot had at least a big toe in the Baroque era of Bach and Handel, as well.
As a child, while his youthful contemporaries were gainfully employed in kicking over garbage cans and pulling the pigtails of young girls, Felix, at the age of 11, was writing fugues. And if his tastes in music were perhaps acquired under the influence of his arch-conservative music teacher, Carl Friedrich Zelter (1758-1832), his championing of the music of Johann Sebastian Bach remained nevertheless a lifelong endeavour. Indeed, the performance of Bach’s St. Matthew Passion at the Singakademie in Berlin in 1829, which Mendelssohn conducted at the age of 20, is credited with initiating the revival of 19th-century interest in Bach’s music.
The String Quartet in A minor Op. 13 was composed in 1827 when Mendelssohn was still establishing himself as the most learned teenage composer in Berlin—admittedly, not a crowded field. Its frequent use of fugal textures attests to the young composer’s admiration for Bach while numerous formal features, especially its cyclical design and recall of themes from earlier movements, point to the influence of Beethoven—the late string quartets and Ninth Symphony in particular.
The first movement opens with an endearing Adagio full of short coy phrases which lead to a repeated three-note motive (C# B D) derived from one of Mendelssohn’s own songs (Frage Op. 9 No. 1). This motive will recur throughout the entire quartet, either in its dotted rhythm or in its melodic contour stretching over a minor 3rd. Lyrical repose, however, is in short supply in the remainder of the first movement. The Allegro vivace that follows the introductory Adagio is a restless affair that offers up two anxious little themes, both set in a minor key.
But “anxiety” is a relative term. In Beethoven it summons up the panicky feeling that you’re swimming just slightly ahead of a shark—that’s gaining on you. Mendelssohnian anxiety, by contrast, is more like not knowing where you put the car keys.
Imitative counterpoint is pervasive in this movement, not just as a “spot technique” to add intensity to the development section à la Mozart and Haydn, but even in the initial presentation of the movement’s themes.
Fireside coziness arrives in the Adagio non lento with its serene and elegiac melody in the 1st violin, drenched in tearful sigh motives. These sigh motives, chromatically inflected, then become the basis for the full-on fugue that follows—an obvious hommage to a similar fugue in the second movement of Beethoven’s String Quartet in F minor Op. 95. Clever lad that he is, young Felix even inverts his fugue subject before returning to the poised serenity of the opening.
In place of a scherzo, Mendelssohn gives us a relaxed and unbuttoned intermezzo. The tune that begins the movement is of the utmost simplicity, one that uses the same catchy rhythm four times in a row, without somehow becoming tiresome. In the middle section trio, however, Mendelssohn returns to type with a fleet and light-footed romp of detached 16ths lightly peppered with repeated notes. And who could resist combining these two contrasting sections in the movement’s final bars? Certainly not Mendelssohn.
High drama marks the opening to the Presto finale, with a flamboyant and wide-ranging recitative in the 1st violin holding forth over melodramatic tremolos below. The reference to the finale of the Ninth Symphony is obvious but this opening is even more closely patterned on the last movement of Beethoven’s A minor Quartet Op. 132 (next on the program). The troubled theme that emerges is similar in mood, as well, to the rocking main theme of Beethoven’s Op. 132 finale. Pacing back and forth in tonal space over a harmonically restless cello line it eventually issues into a cross-country horse-gallop before “remembering” the fugue subject from the second movement in a series of flashbacks. The work closes with the same lyrical Adagio with which it opened, framing the quartet’s inner drama as a gently fading memory.
Ludwig van Beethoven
Quartet No. 15 in A minor Op. 132
Beethoven’s late string quartets are at one and the same time backward-looking, progressive, and even visionary works. The fascination he entertained in his last years for densely contrapuntal textures and the arcane procedures of canon and fugue harkened back to the Baroque era. His expansion of the number of movements in a serious work, along with innovations in the formal design of each movement, moved well beyond the norm of Classical-era practice. And his use of increasingly numerous, increasingly precise performance markings, along with his abrupt dynamic and tempo changes, bespoke a type of music that moved at the pace of human thought, in response to the impulses of an individual personality, offering a foretaste of the Romantic movement to come.
All these traits are on display in his Quartet in A minor Op. 132, composed in 1825.
The quartet unfolds in five movements instead of the usual four, arranged symmetrically around a central slow movement. The work opens with a slow introduction fixated on the overlapping entries of a four-note fugue-like subject in long notes that does more than simply set up the off-to-the-races arrival of the movement’s first theme, announced by the cello high in the soprano register. Pay attention to these opening bars: the long notes of this theme, and the intervals out of which it is constructed (especially the descending semitone), will haunt the entire first movement with the magisterial authority of a Baroque fugue subject in augmentation hovering over melodic motion in smaller note values.
Audience members enjoying a double espresso at the intermission will undoubtedly notice the similarity between the theme of this slow introduction and the subject of the Bach fugue which began the program: both are structured around the leap of a minor 6th with semitone motion on either side. Those opting instead for a Red Bull will in addition notice the similarity between the principal motive of Beethoven’s first theme—stepwise motion up and down over a minor 3rd—and the Bach fugue’s countersubject. Devilishly clever programming on the part of these Danish lads, what?
Despite the frequently grave demeanour of its contrapuntal rhetoric, this movement is anything but down-in-the-mouth. On the whole it is bursting with self-confidence—of a somewhat volatile sort—and offers up a good measure of animated instrumental dialogue. Its lyrical second theme, for example, arriving in the 2nd violin over a somewhat loopy accompaniment in undulating triplets, is eminently hummable.
The second movement is not a standard scherzo, but rather an eccentrically mincing minuet and trio. It’s a minuet that thinks it’s a scherzo, though, in the way it tosses short phrases and small motivic fragments back and forth, cleverly manipulated to create a fair bit of metrical “wobble” in the ear. The middle-section Trio is part musette, with a drone in the bass supporting wispy musings in the high treble, and part oom-pah-thumping village dance.
Beethoven reveals the inspiration for his slow movement in its titling: Heiliger Dankgesang eines Genesenen an die Gottheit, in der lydischen Tonart (Holy song of a convalescent to the Deity, in the lydian mode). The ‘convalescence’ referred to is the composer’s welcome deliverance in 1825 from a painful intestinal condition that had plagued him for some time. This extraordinarily long movement is structured in alternating sections of pious prayer and joyful deliverance as the composer moves from Heaven-directed thoughts of gratitude to buoyant feelings of corporeal invigoration.
The movement opens solemnly, in the manner of a hymn, with overlapping entries in strict imitation. The antiquarian religious feel of this opening is enhanced by its being written in one of the old church modes. (The lydian mode is simply the F major scale with B natural instead of B flat.) This is followed by a section entitled Neue Kraft fühlend (Feeling new strength) and what a change in mood this is! Leaping octaves and sprightly trills sonically attest to the composer’s bright new outlook on life until thoughts of his indebtedness to the Almighty return. Each subsequent appearance of these alternating sections is a more florid variation of the previous until the movement ends in the celestial regions of each instrument’s highest register.
The 4th movement brings us back down to earth with a short rollicking little march, even more metrically ambiguous than the previous minuet. But then, as if an opera character had just rushed on stage with dramatic news, the 1st violin erupts into a declamatory recitative (like that in the finale of the Ninth Symphony) over a fretting bed of tremolo strings below.
The theme that emerges out of all this theatrical drama to begin the quartet’s last movement is surprisingly subdued. Wistful but restless, serene but strangely urgent, its gently rippling texture reminds us of Brahms. A rip-roaring development section follows, with plenty of contrapuntal interplay, but then, as in many a Beethoven final movement, minor turns to major, trouble turns to triumph, and the same musical motives that caused all that brow-knitting at the beginning of the movement become, in the end, a cause for joyous celebration.
