In the realm of music theory, the concept of a sequence plays a central role. A sequence is a series of musical phrases or chords that repeat in succession, typically with a consistent pattern of notes or intervals. It is closely related to repetition, imitation, and variation. Repetition involves the exact reproduction of a musical idea, while imitation involves the restatement of a melody or rhythmic pattern at a different pitch or time. Variation, on the other hand, involves modifying a musical idea while maintaining its essential characteristics.
Definition of Sequence in Music
In music theory, a sequence is a pattern of notes or chords that is repeated at different pitch levels. It is a fundamental element of musical form and can be used to create a sense of movement, development, and continuity within a piece of music.
Structure of a Sequence
A sequence typically consists of the following elements:
- Motive: A short melodic or rhythmic figure that is repeated throughout the sequence.
- Sequence: The repetition of the motive at different pitch levels.
- Consequent: The repetition of the motive in a different voice or instrument.
Types of Sequences
There are two main types of sequences:
- Real sequence: The motive is repeated exactly at a different pitch level.
- Tonal sequence: The motive is repeated with some variation in pitch or harmony.
Table of Sequence Structures
| Type | Description | Example |
|---|---|---|
| Real sequence | Motive repeated exactly at different pitch levels | C D E | G A B |
| Tonal sequence | Motive repeated with some variation in pitch or harmony | C D E | G A♭ B♭ |
| Harmonic sequence | Chord progression repeated at different pitch levels | C major | G major | D major |
| Melodic sequence | Melodic line repeated at different pitch levels | C D E F G | G A B C D |
Functions of Sequences
Sequences serve a variety of functions in music, including:
- Providing a sense of motion and development
- Creating contrast and variety
- Reinforcing melodic and harmonic ideas
- Enhancing the structural integrity of a piece
Example of a Sequence in Music
Consider the following excerpt from the opening of Handel’s “Hallelujah” chorus:
- Motive: The ascending scale pattern in the soprano voice.
- Sequence: The repetition of the motive at different pitch levels in the alto, tenor, and bass voices.
- Consequent: The restatement of the motive in the soprano voice at a higher pitch level.
This sequence creates a sense of excitement and anticipation as the chorus builds towards its climax.
Question 1:
What is the definition of a sequence in music?
Answer:
A sequence in music is a series of notes that follow a specific pattern of pitch and duration.
Question 2:
How is a sequence different from a melody?
Answer:
A sequence is distinct from a melody in that it strictly adheres to a fixed pattern of pitch intervals and rhythmic values, whereas a melody can exhibit more variation and flexibility in its melodic contour.
Question 3:
What are the characteristics of a harmonic sequence?
Answer:
A harmonic sequence is a series of chords that progress in a specific pattern of harmonic intervals and cadential formulas, typically creating a sense of rhythmic drive and resolution.
