OVERVIEW
Musical form refers to the way a musical piece is structured,
shaped, and or ga nized. Chapter6 focuses on the key ele ments
of music that define musical form: contrast, repetition, and
variation. The chapter also explores a few examples of musi-
cal forms that have had lasting value in music from around
the world.
LEARNING OBJECTIVES
1. To understand form as the organ izing princi ple in
music
2. To understand that the key ele ments of form are contrast,
repetition, and variation
3. To understand and identify the basic structures of
strophic, binary, ternary, and responsorial (call- and-
response) form
4. To understand theme and motive as the melodic build-
ing blocks of musical form
5. To understand sequence and ostinato as common proce-
dures of repetition and pattern employed in music
OUTLINE
I. Structure and Design in Music
A. Form: organ izing princi ple in music
1. work’s structure or shape
2. repetition and contrast: unity and variety
3. variation: only some aspects of music altered
4. vocal forms:
a. strophic: same melody with each stanza of
text
b. through- composed: no main section repeated
5. improvisation: pieces created spontaneously in
performance
a. pre- established harmonic pattern, time frame,
melodic outline
b. balanced by structural princi ples
B. Binary and ternary form
1. binary (two- part) form: (A- B)
a. statement and departure
2. ternary (three– part) form: (A– B- A)
a. statement, departure, and return of original
statement
II. The Building Blocks of Form
A. Theme: main melodic idea used as building block
in construction of a larger work
1. motive: small fragment of a theme
B. Thematic development: expansion of a theme
1. larger forms: provides clarity, coherence, logic
2. varied melody, rhythm, or harmony
3. procedures:
a. repetition: exact or varied
b. sequence: idea restated at higher or lower pitch
C. Other formal procedures
1. call- and- response (responsorial music): singing
leader answered by chorus of followers
