Chapter 4 Musical Form and Musical Style Form in Music Key Terms Form Memory Outer form Inner form Repetition Contrast Return Variation Genre Form in Music Overall shape of a musical work Arrangement, relationship, or organization of various elements of music • • • • • • • Rhythm Pitch and melody Dynamics Harmony Tone color Texture Tonality Form in Music Musical works can divide into clear sections with clear-cut relationships or unfold gradually and organically Form is not purely intellectual Our experience of form shapes our emotional response to a work The emotional trajectory of a work is forged by careful use of repetition and contrast Form in Music Musical works are formed through repetitions and contrasts of elements • Repetitions may be strict or free • Contrasts may be subtle or dramatic Repetitions and contrasts define relationships between phrases of a melody or sections of a work Memory is the key to hearing these relationships as they unfold in time Form in Music Possible relationships between phrases, themes, or sections Repetition (a a) • Parallelism • Identical or nearly identical restatement of a phrase, theme, or section • Feels reassuring, but lacks excitement Form in Music Possible relationships Contrast (a b) • A new phrase or section • May have subtle connections to previous material, or may be entirely new • Provides excitement of new phrase, theme, or section, but doesn’t feel stable or complete Form in Music Possible relationships Variation (a a’) • A restatement of previous material, but one or more elements are altered • Simultaneous repetition and contrast • Similar enough to sound like the same idea, but definitely not identical • Variation can change or transform the mood or feeling of a phrase, theme, or section Form in Music Possible relationships Contrast and return (a b a) • Unlike repetition, return is restatement of original material after contrasting material • You can’t return home if you never leave! • Commonly used, emotionally satisfying formula (unity and variety) • Combines excitement of new material and sense of relief with return of familiar material (homecoming) Listening for Form Try several examples—which of these do you hear? Repetition? Contrast? Variation? Contrast and return? Form and Forms Form is organization of elements in a work A form refers to one of many standardized patterns used by composers Possible forms include: • • • • • Strophic form (A A A …) Ternary form (A B A) Fugue Baroque dance form (aabb) Sonata form Form and Forms An example: A B A form Three large sections: statement, contrast, return Each section might have its own form • A=aba • B=cdc • A=aba Such “nesting” arrangements are often used to create more complicated forms Form and Forms “Outer” and “inner” form Standard patterns outline a work’s overall shape—its “outer” form (e.g., A B A) “Outer” forms are reassuring, provide a satisfying, easy-to-follow overall shape “Outer” forms do not describe the content of each section, its moment-to-moment inner workings, or the feel of contrasting material—its “inner” form Form and Forms “Inner” Form Take any work in A B A form • Is B in a different mode or key? • Is B’s contrast due to rhythm, texture, tone color, or some other element? • Does the return convey excitement, trickiness, or relief? Take any other work in A B A form • The answers will be different! Same “outer” form, different “inner” form Musical Genres Categories or types of musical compositions A genre can be defined by a its: • Performing forces (number and kind of instruments or voices used) • Function or purpose • Text Not to be confused with form Musical Genres Examples of genres: • • • • • • • • • Concerto Mass Oratorio Symphony Sonata String quartet Song cycle Madrigal Opera Genre vs. Form A genre is defined by its broadest features (performers, function, etc.) A form is defined by its internal sections and their interrelationships Genre vs. Form In literature, poetry is a genre • • • • A work in verse Usually breaks down into stanzas and lines Often uses poetic meter and rhyme Traditionally intended for public reading Haiku, sonnets, and limericks are forms • Each has a specific number of lines (3, 14, and 5, respectively) • Each uses a specific poetic meter (or specific number of syllables per line) • The last two have an expected rhyme scheme Genre vs. Form In music, the symphony is a genre • a large work in several movements for orchestra (performing forces) • written for entertainment at a public concert (function) Each movement of a symphony may use a different form—Haydn’s 95th uses: • • • • Sonata form Theme and variations Minuet form Rondo form Listening for Genre Try several examples—answer these questions: What is the function of this music? • Public or private entertainment? Worship? Patriotic? Commercial? What are the performing forces? • Orchestra? String quartet? Chorus? Solo voices? Piano? Rock band? Jazz combo? What is the genre?
