Double variation

The double variation (also known as alternating variations) is a musical form used in classical music. It is a type of theme and variations that employs two themes. In a double variation set, a first theme (to be called A here) is followed by a second theme (B), followed by a variation on A, then a variation on B, and so on with alternating A and B variations. Often there is a coda at the end.

The double variation is strongly associated with the composer Joseph Haydn, who wrote many such movements during his career.

The double variation in Haydn

The double variation first appears Haydn's work of the 1770s. Haydn may have been inspired by an earlier example of Carl Philipp Emanuel Bach, the sixth of that composer's Sonatas with Varied Reprises, (W. 50/6, H. 140), in C minor (1760). Elaine Sisman, an authority on variations, notes "This set of sonatas was advertised in Vienna several times in the period in which Haydn wrote his first [double] variations."^[1]

While Haydn's double variations show considerable diversity, there are some general patterns.

• Both themes have the same tonic, but in opposite modes, so that if A is major, B is minor, and vice versa.
• The second theme is usually thematically reminiscent of the first, though not so close as to be an actual variation of it.
• The total number of variations is small, often just one or two for each theme.
• The number of variations is (with just one exception) arranged to place the major theme last. Thus, if the first theme is major, Haydn generally uses ABABA form, but if the first theme is minor, Haydn uses ABABAB.

As Haydn's career proceeded, he moved toward a very particular type of double variations, having the following additional specific characteristics.

• The tempo is moderate, typically andante.
• The minor theme is placed first.
• Each theme is divided into two sections, and each section is repeated.
• The internal arrangement of both themes is often that of sonata form, with the music moving to the dominant or relative major key in the first part, to remote keys in the first half of the second part, and then to a recapitulation of the opening material in the tonic key. This observation is made by Charles Rosen (in The Classical Style) concerning the double variations in the Drumroll Symphony; it holds true in several other cases as well.
• While assessments of emotional content are necessarily subjective, it is reasonable to claim that the minor themes sound tense and the major themes blissful. Jean-Yves Bras, writing in program notes for a performance of the Piano Trio H:23 (Harmonia Mundi 901400), describes the minor and major themes "somber" and "radiant", respectively. Charles Rosen, writing of the major theme from the Piano Trio H. 13, says that in it Haydn created "an emotion that was completely his own and that no other composer, not even Mozart, could duplicate - a feeling of ecstasy that is completely unsensual, almost amiable." Rosen's remark could be applied to several of the other major double variation themes.

List of works by Haydn written in double variation form

According to Sisman,^[1] Haydn wrote 21 double variation movements. Sisman's list is restated below in chronological order. Where different authorities provide different dates, both are given; NG = the New Grove (used by Sisman), MH = Maurice Hinson's edition of the piano sonatas.^[2] For the keys of the A and B sections, lower case designates minor; upper case major. The structural synopses are taken from Sisman with minor corrections; in Sisman's notation an asterisk means "altered".

The double variation in Beethoven

Although the double variation is associated strongly with Haydn, Elaine Sisman has pointed out that, provided we adopt a somewhat looser definition of the form, Ludwig van Beethoven also emerges as a major composer of double variations.^[1] With the partial exception of the Piano Trio in E flat major, Op. 70 No. 2, which Sisman sees as an homage to Haydn, Beethoven's double variations have a rather different character. For instance, sometimes only the A theme is strongly varied, with B remaining relatively constant. Beethoven also likes to interrupt or truncate one or both themes, producing a less regular structure than Haydn's, seen in the often-complex structural formulae given below.

Thus flexibly construed, the double variation emerges as the musical form for some of the most famous of Beethoven's works. Here is a list of movements for which Sisman argues that a double-variation structure is present.

Year	Work	Form	A	B
1802	Third Symphony. 4: Allegro molto	AA1A2BAxB1A3B2Ax1B3B4coda	various, centered on E♭	various, centered on E♭

1825	String Quartet No. 15, Op. 132. 3: Molto Adagio — Andante ("Heiliger Dankgesang")	ABA1B1A2	F Lydian, notated C	D

As Sisman notes, Beethoven placed his double variations in the same genres as Haydn: the piano trio, the string quartet, and the symphony.

Later double variations

After Beethoven, the double variation appears to have been only seldom employed. The following list is ordered chronologically.

Brahms

The second movement of Johannes Brahms' String Quintet No. 1 (1882) is described by Joanna Wyld^[3] as a set of double variations.

Bruckner

The second movement of Anton Bruckner's Seventh Symphony (1883/1885) is described by A. Peter Brown^[4] as a set of double variations.

Dvořák

The Larghetto movement of Antonín Dvořák's String Quintet Op. 97 (1893) is described by Colin Lawson ^[5] as a set of double variations.

Harper

A set of double variations for oboe, bassoon and orchestral wind ensemble by Edward Harper was premiered in 1989; see program notes.

Other senses of the term "double variation"

Distinct variations for repeated sections

Occasionally, authors on music use the term "double variation" in a quite different sense. This definition presupposes that the theme consists of two parts, each one repeated (that is, AABB). In a double variations of this kind, each repeat gets its own variation, as shown below:

AABB A₁A₂B₁B₂ A₃A₄B₃B₄ ...

Alternatively, some of the variations can be single (A_xA_xB_xB_x) and others double.

An example of this usage is found in Cedric T. Davie's discussion ^[6] of the last movement of Beethoven's Piano Sonata Opus 109, in which some but not all of the variations are double in the intended sense. The full formula for this movement (adapting Davie's verbal description) is:

Theme: AABB

I. A₁A₁B₁B₁

II. A₂A₃B₂B₃

III. A₃A₄B₃B₄

IV. A₅A₅B₅B₅

V. A₆A₇B₆B₇

VI. A₈A₉B₈B₉

Coda, incorporating the original AABB

The two kinds of "double variation" are not mutually exclusive. In Haydn's Piano Trio H:13, the first movement is a double variations in the first sense given in this article (that is, it takes the form ABA₁B₁A₂B₂), and the last variation of the B theme (B₂) is a double variation in the second sense, with different treatment of the repeats in each half of the theme. There appears to be no standard nomenclature for keeping the two senses distinct.

"Double" as designating a single variation

In the Baroque dance suite, a dance movement was sometimes immediately followed by a single variation, which was called the "double". ^[7]
