B. Strict imitation
1. canon: each voice enters in succession with the
same melody
2. round: perpetual canon (e.g., Row, Row, Row
Your Boat)
OVERVIEW
The intermingling of melody and harmony provides the basis
of musical texture. More specifically, texture can be described
as monophonic, homophonic, polyphonic, or homorhythmic,
depending on how harmony and melody interact with each
other in a musical passage. This chapter introduces students
to the basic types of textures in Western art music.
LEARNING OBJECTIVES
1. To understand texture as the interweaving of melody
with harmony
2. To understand and identify the basic textures of monoph–
ony, homophony, polyphony, and homorhythm
3. To understand and identify the contrapuntal devices of
imitation, canon, and round
LECTURE SUGGESTIONS
1. After defining monophonic, polyphonic, homophonic,
and homorhythmic texture, play the following se lections
for the class:
Hildegard of Bingen: Kyrie
J. S. Bach: Jesu, Joy of Man’s Desiring (at 0:20)
OUTLINE
I. Types of Texture
A. Monophony
1. single voice (sung or instrumental)
2. one line of music without accompaniment
3. one focus, single line of melody
B. Heterophony
1. melody combined with ornamented version of
itself
a. several musicians sing/play same musical line,
each varies some ele ment (e.g., pitch or rhythm)
b. subtle, nuanced variations
c. may sound “out of sync”
2. common texture in non- Western cultures
3. jazz and spirituals depend on heterophonic
texture
C. Polyphony
1. two or more melodic lines combined
2. based on counterpoint
3. requires more experienced listening
D. Homophony
1. melody (primary focus) with harmonies
a. chords support, enhance principal line
2. traditional and popu lar styles
3. homorhythmic: all voices move in same rhythm
a. vertical conception; hymns
b. melody: most obvious line
E. Textures may vary within a composition
II. Contrapuntal Devices: Types of Polyphony
A. Imitation
1. melodic idea presented then restated in another
voice
2. may be brief, or may last the entire work
3. unifying technique in polyphony
