HARMONY<br />

IN LILBURN<br />

If anyone particular element was to epitomize the changes in<br />

Lilburn's composition style throughout his output, it would be that <strong>of</strong><br />

harmony.<br />

to define his style.<br />

Obversely, it is also this element that arguably most helps<br />

<strong>The</strong> <strong>music</strong> <strong>of</strong> Lilburn's first composition period is strongly<br />

triadic, yet, unlike his use <strong>of</strong> form, for example, his harmonic<br />

vocabulary does not remain fixed <strong>and</strong> constant throughout this period.<br />

Whilst continuing to be triadic, it shows a slow evolution from the<br />

diatonic modality <strong>of</strong> the early overtures to the chromatiG parallelism<br />

<strong>of</strong> his second symphony;<br />

or rather, it is a slow expansion, for his<br />

harmony never really severs its diatonic modal roots.<br />

A facet <strong>of</strong> Lilburn's harmonic technique that recurs throughout<br />

his output is his use <strong>of</strong> pedal points. A brief examination <strong>of</strong> a few<br />

carefully chosen extracts will serve to illustrate his use <strong>of</strong> this<br />

device. More importantly though, these extracts will serve as a good<br />

illustrative introduction to the exp<strong>and</strong>ing nature <strong>of</strong> his harmonic<br />

vocabulary throughout his first composition period.<br />

<strong>The</strong> first extract (Ex.l) is from the A~tearoa Overture <strong>of</strong> 1940.<br />

It shows the weaving <strong>of</strong> strictly diatonic chords. above a tonic (G) pedal.<br />

<strong>The</strong> material that forms the basis <strong>of</strong> this extract is drawn from the<br />

introduction section <strong>of</strong> the overture.<br />

Ex.l: Aotearoa Overture, strings bars 135-42, piano reduction.<br />
