Musical Phrases

A musical phrase consists of a presentation phase and a continuation phase, forming a complete eight-bar music theme that must end with a cadence.

Presentation Phase (First Four Bars) - Methods of Melody Repetition:

  • Exact Repetition

    Completely identical repetition

    Adjusting melody pitch

    Slightly modifying the melody

  • Sequential Repetition

    Raising or lowering the melody and harmony simultaneously by the same interval

    Variable sequential progression (third relationship)

    Strict sequential progression (major third relationship)

  • Statement-Response Repetition

    Must use the tonic chord as a question, and respond with the dominant chord

    Involves the technique of Transposition

    Transposition: List the notes in the chord, resolve the notes in the melody to the stable note of the transposed key, and modify the interval relationships that are not on the tonic pitch level. (Simple method description)

Continuation Phase (Last Four Bars) - Techniques:

  • Surface Rhythm Acceleration

    Melodic development = controlling tension

    Controlling tension:

    • Accumulating tension: Using short notes
    • Accumulating tension: Ascending progression
    • Releasing tension: Using long notes
    • Releasing tension: Descending progression

    Melodic acceleration: Shortening the duration of melody notes

  • Harmonic Acceleration

  • Sequential Progression

  • Fragmentation

    Musical “fragments”

    Extracting original melody fragments

    Developing new melodies

  • Liquidation

Musical Period

Definition: A musical period is an eight-bar music theme consisting of two parts, called the Antecedent Phrase and the Consequent Phrase.
