Melodic contour and structure are crucial elements in crafting memorable tunes. They shape how a melody moves and feels, influencing its emotional impact. Understanding these concepts helps you create more engaging and expressive musical lines.
From basic shapes to complex structures, melodic construction offers endless possibilities. By mastering techniques like building, climax creation, and harmonic interplay, you'll develop the skills to write compelling melodies that resonate with listeners.

Melodic contour describes the overall shape and direction of a melodic line
Can be ascending (rising), descending (falling), arched (rising then falling), wavy (alternating up and down), or static (staying on the same pitch)
Melodic intervals are the distances between consecutive pitches in a melody
Measured in scale steps or semitones (half steps and whole steps)
The size and direction of intervals contribute to the overall contour of the melody
Smaller intervals create a smoother contour, while larger intervals create a more angular or disjunct contour
occurs when a melody moves by step, using adjacent notes in the scale
Creates a smooth, flowing sound (C-D-E or E-D-C)
involves leaps between non-adjacent notes
Creates a more angular, jagged sound (C-G-E or G-C-A)
Melodies often combine both conjunct and disjunct motion for variety and interest
Range and Expression
is the distance between the lowest and highest pitches in a melody
Can affect the expressive qualities of the melody
A wide range can create a sense of grandeur or intensity, while a narrow range can create a sense of intimacy or simplicity
The choice of instrument or voice to perform a melody may depend on its range (soprano vs bass)
The shape and direction of a melody can convey different emotions or moods
Ascending melodies can suggest positive emotions like joy, hope, or excitement
Descending melodies can suggest negative emotions like sadness, despair, or resolution
Arched melodies can suggest a sense of growth and decay or tension and release
Static melodies can suggest a sense of stability, tranquility, or stasis
Common Melodic Structures
Phrases and Periods
Phrases are relatively independent musical units that typically end with a or a sense of closure
Melodies are often composed of multiple phrases that are combined to create larger structures
Phrases can be of varying lengths, but are often 2, 4, or 8 measures long
The ending of a phrase is often marked by a cadence, which is a that creates a sense of resolution or tension
Periods are a common melodic form consisting of two phrases, often called antecedent and consequent
The is the "question" or the first half of the , ending with a weak or inconclusive cadence
The is the "answer" or the second half of the period, ending with a strong or conclusive cadence that provides a sense of resolution or completion to the antecedent
Periods are often symmetrical, with the consequent phrase beginning similarly to the antecedent but ending differently to provide closure
Sentences and Sequences
is another common melodic form, featuring three parts:
: a short musical idea that is stated twice, often with a slight variation the second time
: a departure from the initial idea, often featuring fragmentation, sequencing, or harmonic instability
: a concluding phrase that provides a sense of closure or resolution, often featuring a strong cadence
Melodic sequences involve the repetition of a musical pattern at different pitch levels
Can create a sense of unity and forward motion in a melody
Can be ascending (rising in pitch), descending (falling in pitch), or chromatic (moving by semitones)
Sequences can be exact (repeating the same intervallic pattern) or diatonic (adapting the pattern to fit within a scale or key)
is a melodic structure in which a musical phrase is stated (the call) and then answered or echoed by another phrase (the response)
Often features contrasting musical material between the call and response
Can create a sense of dialogue or conversation between two musical voices or instruments
Commonly used in African-American musical traditions, such as spirituals, blues, and jazz
Climax and Resolution in Melody
Tension and Release
is the highest point of tension or emotional intensity in a melody
Often achieved through a combination of pitch height, rhythmic intensity, and harmonic tension
The climax is the "peak" or "high point" of the melody, after which the tension is released or resolved
The placement of the climax within a melody can vary, but it often occurs near the end of a phrase or section to create a sense of anticipation and release
refers to the sense of closure or completion that follows the climax
Often achieved through a descending melodic line, a return to the tonic pitch, or a resolution of harmonic tension
Resolution provides a sense of stability and satisfaction after the tension of the climax
Can occur immediately after the climax or be delayed for added tension and surprise
Delayed Resolution and Expressive Techniques
occurs when the expected resolution of a melody is postponed or avoided
Creates a sense of tension or surprise that can be resolved later in the piece
Can be achieved through techniques such as , melodic suspensions, or modulations to unexpected keys
Delayed resolution can create a sense of longing, uncertainty, or ambiguity in the melody
Other expressive techniques can be used to enhance the emotional impact of a melody's climax and resolution
Dynamics (loud vs soft) can be used to emphasize the climax or resolution
Articulation (smooth vs detached) can be used to create a sense of urgency or relaxation
(trills, turns, grace notes) can be used to add intensity or elegance to the melody
(flexible tempo) can be used to create a sense of ebb and flow or to highlight important moments in the melody
Melody vs Harmony
Consonance and Dissonance
refers to the simultaneous sounding of pitches to create chords, which provide the underlying structure and context for a melody
Chords are built from intervals (distances between pitches) stacked in thirds
Triads are the most basic type of chord, consisting of three pitches (root, third, fifth)
More complex chords can be created by adding additional pitches or altering existing ones
and describe the perceived stability or instability of the relationship between a melody and its accompanying harmony
Consonant intervals and chords are often used for moments of resolution, as they create a sense of stability and agreement between the melody and harmony
Dissonant intervals and chords can create tension and instability, as they introduce clashing or conflicting pitches that seek resolution
The balance and interplay between consonance and dissonance is a key aspect of musical expression and can vary widely between different styles and genres
Harmonic Rhythm and Progressions
refers to the rate at which the harmony changes in relation to the melody
A slow harmonic rhythm (one chord per measure) can create a sense of stability and spaciousness, allowing the melody to unfold gradually
A faster harmonic rhythm (multiple chords per measure) can generate tension and forward motion, propelling the melody forward
Changes in harmonic rhythm can be used to create contrast and variety within a piece
The choice of harmonic progressions can significantly impact the character and emotional quality of a melody
Different progressions can evoke various moods or styles, such as the "sad" sound of a minor progression or the "heroic" sound of a major progression
Common progressions include:
I-IV-V-I (tonic-subdominant-dominant-tonic)
ii-V-I (supertonic-dominant-tonic)
I-vi-IV-V (tonic-submediant-subdominant-dominant)
Modulations (changes of key) can be used to create variety and contrast within a progression
is a secondary melody that is played simultaneously with the primary melody
Often played in a different voice or instrument to create a sense of dialogue or interaction
The interaction between the two melodies and their respective harmonies can create a rich, layered texture
Countermelodies can be used to reinforce the harmony, create contrast, or add interest to the overall musical texture
