In music, development is a process by which a musical idea is communicated in the course of a composition. It refers to the transformation and restatement of initial material. Development is often contrasted with musical variation, which is a slightly different means to the same end. Development is carried out upon portions of material treated in many different presentations and combinations at a time, while variation depends upon one type of presentation at a time. [2]


In this process, certain central ideas are repeated in different contexts or in altered form so that the mind of the listener consciously or unconsciously compares the various incarnations of these ideas. Listeners may apprehend a "tension between expected and real results" (see irony), which is one "element of surprise" in music. This practice has its roots in counterpoint, where a theme or subject might create an impression of a pleasing or affective sort, but delight the mind further as its contrapuntal capabilities are gradually unveiled.

In sonata form, the middle section (between the exposition and the recapitulation) is called the development. Typically, in this section, material from the exposition section is developed. In some older texts, this section may be referred to as free fantasia.[ citation needed ]

According to the Oxford Companion to Music [3] there are several ways of developing a theme. These include:

The Scherzo movement from Beethoven's Piano Sonata No. 15 in D major, Op 28 (the "Pastoral" Sonata) shows a number of these processes at work on a small scale. Charles Rosen (2002) marvels at the simplicity of the musical material: "The opening theme consists of nothing but four F sharps in descending octaves, followed by a light and simple I/ii/V7/I cadence with a quirky motif repeated four times." [4] These opening eight bars provide all the material Beethoven needs to furnish his development, which takes place in bars 33-48:

The division of a theme into parts

The falling octave in the first two bars and the repeated staccato chord in the left hand in bars 5-8 are the two fragments that Beethoven later develops:

Alteration of pitch intervals

The somewhat bald falling octave idea in the first four bars is transformed in bars 33-36 into an elegant shape ending with an upward-curving semitone:

Rhythmic displacement

In this movement, the repeated left hand chords in bar 5 are displaced so that in bar 33 onwards, they fall on the 2nd and 3rd beats:

Sequence and the development of two or more themes in combination

In bars 33-48, the two fragments combine and the development goes through a modulating sequence that touches on a succession of keys;

The following outline demonstrates Beethoven’s strategic planning, which he applied on a larger scale in the development sections of some of his major works. The bass line traces a decisive progression through a rising chromatic scale:

To quote Rosen again, writing à propos of this movement: "As Beethoven's contemporary, the painter John Constable, said, making something out of nothing is the true work of the artist." [5]

Development on a larger scale

Not all development takes place in what is commonly known as the "development section" of a work. It can take place at any point in the musical argument. For instance, the “immensely energetic sonata movement” [6] that forms the main body of the overture to Mozart’s Opera Don Giovanni announces the following theme during the initial exposition. It consists of two contrasting phrases: “first determined, then soft and conspiratorial.” [7]

William Mann says “the first, insistent phrase [of the above] is very important. At once it is taken up imitatively by various departments of the orchestra, and [starting in] A major, jumps through several related keys.” [8] Each repetition of the descending phrase is subtly altered one note at a time, causing the music to pass from the key of A major, through A minor and thence via a chord of G7 to the remote key of C major, and thence back to A major.

The central section of the Overture (the part commonly known as the "development section") utilizes both phrases of the theme “in new juxtapositions and new tonalities,” [9] developing it through repetition in a modulating sequence. The steady plod of the bass line against the sequential repetitions of the “soft and conspiratorial” [10] phrase outlines a circle of fifths chord progression:

Simultaneously, Mozart adds to the mix and continues to develop the imitative counterpoint that grew out of the first phrase. In the words of Willam Mann, this development “unites both halves” [11] of the theme. This is how this tightly woven texture pans out:

The Piano Sonata No. 11 in A major, K. 331 / 300i, by Wolfgang Amadeus Mozart is a piano sonata in three movements. Mozart likely composed the sonata while in Vienna or Salzburg by around 1783, although Paris and dates as far back as 1778 have also been suggested.

The Piano Sonata No. 12 in F major, K. 332 (300k) by Wolfgang Amadeus Mozart was published in 1784 along with the Piano Sonata No. 10 in C major, K. 330, and Piano Sonata No. 11, K. 331. Mozart wrote these sonatas either while visiting Munich in 1781, or during his first two years in Vienna. Some believe, however that Mozart wrote this and the other sonatas during a summer 1783 visit to Salzburg made for the purpose of introducing his wife, Constanze to his father, Leopold. All three sonatas were published in Vienna in 1784 as Mozart's Op. 6.

The first documented public performance was in 1836 by Franz Liszt in the Salle Erard in Paris.

Piano Concerto No. 24 (Mozart) Concertante work by Wolfgang Amadeus Mozart

The Piano Concerto No. 24 in C minor, K. 491, is a concerto composed by Wolfgang Amadeus Mozart for keyboard and orchestra. Mozart composed the concerto in the winter of 1785–1786, finishing it on 24 March 1786, three weeks after completing his Piano Concerto No. 23 in A major. As he intended to perform the work himself, Mozart did not write out the soloist's part in full. The premiere was in early April 1786 at the Burgtheater in Vienna. Chronologically, the work is the twentieth of Mozart's 23 original piano concertos.

Schuberts last sonatas last major compositions for solo piano by Franz Schubert

Franz Schubert's last three piano sonatas, D 958, 959 and 960, are his last major compositions for solo piano. They were written during the last months of his life, between the spring and autumn of 1828, but were not published until about ten years after his death, in 1838–39. Like the rest of Schubert's piano sonatas, they were mostly neglected in the 19th century. By the late 20th century, however, public and critical opinion had changed, and these sonatas are now considered among the most important of the composer's mature masterpieces. They are part of the core piano repertoire, appearing regularly on concert programs and recordings.

Symphony No. 5 (Beethoven) Musical composition by Ludwig van Beethoven

The Symphony No. 5 in C minor of Ludwig van Beethoven, Op. 67, was written between 1804 and 1808. It is one of the best-known compositions in classical music and one of the most frequently played symphonies, and it is widely considered one of the cornerstones of western music. First performed in Vienna's Theater an der Wien in 1808, the work achieved its prodigious reputation soon afterward. E. T. A. Hoffmann described the symphony as "one of the most important works of the time". As is typical of symphonies during the transition between the Classical and Romantic eras, Beethoven's Fifth Symphony is in four movements.
