Year 9 Arrangement – Harmonic &
Melodic Variation
Reference-
In Tune with Music Book 2, Harmonic Variation p 233, Melodic Variation p 242.
Harmonic Variation
·
Change
the harmonic rhythm; have more or fewer chord changes in a bar.
·
Use
extended versions of the original chords.
Eg 6th, 7th, 11th & 13th
chords
·
Use
completely different chords from the original.
Activity
In groups 2,
work out as many harmonic possibilities for the melody provided. Use the basic
chord structure as a guide.
Typical Chord
Substitutions and suggestions
·
Chord
ii (or chord vi) can often replace chord IV.
·
Chord
iii can often replace chord I when moving to chord IV.
·
Chromatic
chords can be brought in for added colour.
·
Augmented
chords are often used between chords a 4th apart.
·
When
harmonies are repeated in a bar it is often useful to change the harmonic
colour of the repeated chord for variety.
As a class
these chords will then be used to create a new harmonic arrangement on the
board.
Melodic Variation
Rhythm
Anticipation
– Where the note is heard before it would normally be heard.
Delay- Where
the note is heard after it would normally be heard.
Augmentation-Where
the original note lengths are lengthened.
Diminution-
Where the original note values are shortened
Pitch
Repetition
of notes in the melody
Addition of
chordal notes – short notes added to the melody which outline the harmony.
Passing
notes – Notes moving by step between leaps in the melody.
Activity
Using the handout provided modify the
melody using;
Anticipation
[In Bar 1-3] – Where the note is heard before it would normally be heard.
Delay [In
Bar 4-6] - Where the note is heard after it would normally be heard.
Augmentation
[In Bar 7-9] -Where the original note lengths are lengthened.
Diminution
[In Bar 10 & 11] - Where the original note values are shortened.
On the bottom stave of the handout
rearrange the melody using;
·
Repetition
of notes in the melody
&
·
Addition
of chordal notes – short notes added to the melody which outline the harmony.
Extension
Call & response
Where one voice initiate an idea and another follows in a similar or
slightly varied way melodically/rhythmically
Countermelody
A second melody (directly) above or below the main melody
Cross rhythm/ polyrhythm
Two different rhythms used at the same time, eg 2 quavers in the melody
and triplet quavers in the bass
Imitation
Repetition by one or more different voices/instruments of a phrase
Sequence
Repetition of a musical phrase at a higher or lower pitch
Ostinato
A repeated accompaniment pattern that can be rhythmic or melodic,
maintained throughout the section/piece
Riff
Jazz/rock equivalent of ostinato
