Imitative
texture:
Imitation
is a special type of polyphonic texture produced whenever a
musical idea is ECHOED from "voice" to "voice". Although imitation can be
used in monophonic styles, it is more prevalent in polyphonic art-music—
especially from the Renaissance and Baroque periods.

MUSICAL FORM
The large-scale
form
of a musical composition can be projected via any
combination of the musical elements previously studied. Traditionally, however,
musical form in Western music has been primarily associated with the order of
melodic, harmonic and rhythmic events (or the text) in a piece. Letters (
i.e.
, A, B, C)
are used to designate musical divisions brought about by the repetition of melodic
material or the presentation of new, contrasting material. Some of the most common
musical forms are described below:
BASIC FORMS
(more sophisticated forms will be covered later in this book)
Strophic Form
: a design in VOCAL music, in which the same music is used
for several different verses (strophes) of words. [Example: "
Deck the
Halls
" has many verses of words sung to the same music.]
Verse 1 . . . Verse 2 . . . Verse 3 (etc.)
Through-composed
a structure in which there is no repeat or return of any
large-scale musical section. [Example: Schubert's "
Erlkönig
".]
A
B
C
D
E . . .
Binary Form
a two-part form in which both main sections are repeated (as
indicated in the diagram by "repeat marks"). The basic premise of this
form is CONTRAST:
Ternary Form
a three-part form featuring a return of the initial music after a
contrasting section. Symmetry and balance are achieved through this
return of material:
