In classical music, a fugue is a contrapuntal, polyphonic compositional technique in two or more voices, built on a subject that is introduced at the beginning in imitation, which recurs frequently throughout the course of the composition. It is not to be confused with a fuguing tune, which is a style of song popularized by and mostly limited to early American music and West Gallery music. A fugue usually has three main sections: an exposition, a development, and a final entry that contains the return of the subject in the fugue's tonic key. Fugues can also have episodes—parts of the fugue where new material is heard, based on the subject—a stretto, when the fugue's subject "overlaps" itself in different voices, or a recapitulation. A popular compositional technique in the Baroque era, the fugue was fundamental in showing mastery of harmony and tonality as it presented counterpoint.
Ternary form, sometimes called song form, is a three-part musical form consisting of an opening section (A), a following section (B) and then a repetition of the first section (A). It is usually schematized as A–B–A. Prominent examples include the da capo aria "The trumpet shall sound" from Handel's Messiah, Chopin's Prelude in D-Flat Major "Raindrop", and the opening chorus of Bach's St John Passion.
In music, modulation is the change from one tonality to another. This may or may not be accompanied by a change in key signature. Modulations articulate or create the structure or form of many pieces, as well as add interest. Treatment of a chord as the tonic for less than a phrase is considered tonicization.
Modulation is the essential part of the art. Without it there is little music, for a piece derives its true beauty not from the large number of fixed modes which it embraces but rather from the subtle fabric of its modulation.
A refrain is the line or lines that are repeated in music or in poetry — the "chorus" of a song. Poetic fixed forms that feature refrains include the villanelle, the virelay, and the sestina.
In music, form refers to the structure of a musical composition or performance. In his book, Worlds of Music, Jeff Todd Titon suggests that a number of organizational elements may determine the formal structure of a piece of music, such as "the arrangement of musical units of rhythm, melody, and/or harmony that show repetition or variation, the arrangement of the instruments, or the way a symphonic piece is orchestrated", among other factors. It is, "the ways in which a composition is shaped to create a meaningful musical experience for the listener."
"Form refers to the largest shape of the composition. Form in music is the result of the interaction of the four structural elements described above [sound, harmony, melody, rhythm]."
In Western musical theory, a cadence is the end of a phrase in which the melody or harmony creates a sense of full or partial resolution, especially in music of the 16th century onwards. A harmonic cadence is a progression of two or more chords that concludes a phrase, section, or piece of music. A rhythmic cadence is a characteristic rhythmic pattern that indicates the end of a phrase. A cadence can be labeled "weak" or "strong" depending on the impression of finality it gives.
Ludwig van Beethoven's Piano Sonata No. 29 in B♭ major, Op. 106 is a piano sonata that is widely viewed as one of the most important works of the composer's third period and among the greatest piano sonatas of all time. Completed in 1818, it is often considered to be Beethoven's most technically challenging piano composition and one of the most demanding solo works in the classical piano repertoire. The first documented public performance was in 1836 by Franz Liszt in the Salle Erard in Paris to an enthusiastic review by Hector Berlioz.
In music, a pedal point is a sustained tone, typically in the bass, during which at least one foreign harmony is sounded in the other parts. A pedal point sometimes functions as a "non-chord tone", placing it in the categories alongside suspensions, retardations, and passing tones. However, the pedal point is unique among non-chord tones, "in that it begins on a consonance, sustains through another chord as a dissonance until the harmony", not the non-chord tone, "resolves back to a consonance".
Strophic form – also called verse-repeating form, chorus form, AAA song form, or one-part song form – is a song structure in which all verses or stanzas of the text are sung to the same music. Contrasting song forms include through-composed, with new music written for every stanza, and ternary form, with a contrasting central section.
The 32-bar form, also known as the AABA song form, American popular song form and the ballad form, is a song structure commonly found in Tin Pan Alley songs and other American popular music, especially in the first half of the 20th century.
Song structure is the arrangement of a song, and is a part of the songwriting process. It is typically sectional, which uses repeating forms in songs. Common forms include bar form, 32-bar form, verse–chorus form, ternary form, strophic form, and the 12-bar blues. Popular music songs traditionally use the same music for each verse or stanza of lyrics. Pop and traditional forms can be used even with songs that have structural differences in melodies. The most common format in modern popular music is introduction (intro), verse, pre-chorus, chorus, verse, pre-chorus, chorus, bridge, and chorus. In rock music styles, notably heavy metal music, there is usually one or more guitar solos in the song, often found after the middle chorus part. In pop music, there may be a guitar solo, or a solo performed with another instrument such as a synthesizer or a saxophone.
Verse–chorus form is a musical form going back to the 1840s, in such songs as "Oh! Susanna", "The Daring Young Man on the Flying Trapeze", and many others. It became passé in the early 1900s, with advent of the AABA form in the Tin Pan Alley days. It became commonly used in blues and rock and roll in the 1950s, and predominant in rock music since the 1960s. In contrast to 32-bar form, which is focused on the refrain, in verse–chorus form the chorus is highlighted.
Symphony No. 35 in D major, K. 385, also known as the Haffner Symphony, was composed by Wolfgang Amadeus Mozart in 1782. It was commissioned by the Haffners, a prominent Salzburg family, for the occasion of the ennoblement of Sigmund Haffner the Younger. The Haffner Symphony should not be confused with the eight-movement Haffner Serenade, another piece Mozart wrote on commission from the same family in 1776.
In music, the Italian term stretto has two distinct meanings:
- In a fugue, stretto is the imitation of the subject in close succession, so that the answer enters before the subject is completed.
- In non-fugal compositions, a stretto is a passage, often at the end of an aria or movement, in faster tempo. Examples include the end of Franz Liszt's transcendental etude No.10, the end of the last movement of Beethoven's Fifth Symphony; measure 227 of Chopin's Ballade No. 3; measures 16-18 of his Prelude No. 4 in E minor; and measure 25 of his Etude Op. 10, No. 12, "The Revolutionary."
In music, a section is a complete, but not independent, musical idea. Types of sections include the introduction or intro, exposition, development, recapitulation, verse, chorus or refrain, conclusion, coda or outro, fadeout, bridge or interlude. In sectional forms such as binary, the larger unit (form) is built from various smaller clear-cut units (sections) in combination, analogous to stanzas in poetry or somewhat like stacking Lego.
In musical form and analysis, exposition is the initial presentation of the thematic material of a musical composition, movement, or section. The use of the term generally implies that the material will be developed or varied.
Johann Sebastian Bach composed the church cantata Brich dem Hungrigen dein Brot, BWV 39, in Leipzig and first performed on 23 June 1726, the first Sunday after Trinity that year. Three years earlier, on the first Sunday after Trinity in 1723, Bach had taken office as Thomaskantor and started his first cycle of cantatas for Sundays and Feast Days in the liturgical year. On the first Sunday after Trinity in 1724, he began his second cycle, consisting of chorale cantatas. The cantata Brich dem Hungrigen dein Brot is regarded as part of Bach's third cantata cycle which was written sporadically between 1725 and 1727.
The Clavier-Übung III, sometimes referred to as the German Organ Mass, is a collection of compositions for organ by Johann Sebastian Bach, started in 1735–36 and published in 1739. It is considered Bach's most significant and extensive work for organ, containing some of his most musically complex and technically demanding compositions for that instrument.
The String Quartet in D major is the only string quartet composed by César Franck. The work was written from 1889 to 1890.
In music, particularly Western popular music, a post-chorus is a section that appears after the chorus. The term can be used generically for any section that comes after a chorus, but more often refers to a section that has similar character to the chorus, but is distinguishable in close analysis. The concept of a post-chorus has been particularly popularized and analyzed by music theorist Asaf Peres, who is followed in this article.
