interchange <strong>of</strong> mode above a single tonic (a shift in the lateral index<br />

<strong>of</strong> modality Cmajor to C dorian). <strong>The</strong> Symphony No.2 excerpt (see Ex.38)<br />

shows a sequential, non-diatonic use <strong>of</strong> a succession <strong>of</strong> triads (both<br />

major <strong>and</strong> minor) in a mixture <strong>of</strong> root positions <strong>and</strong> first inversions:<br />

<strong>The</strong> superficial resemblances between these two extracts are quite<br />

remarkable. <strong>The</strong> only feature that distinguishes one from the other is<br />

the harmonic content: the Symphony No.2 extract is more daring in its<br />

departure from diatonicism. Even that distinction, considering that the<br />

harmony for both extracts is derived from different compositional<br />

processes, is only slight. Juxtaposed, these two extracts, composed<br />

eleven years apart, clearly show the stylistic consistency <strong>of</strong> Lilburn's<br />

works from his first composition period.<br />

Throughout his first period <strong>of</strong>'composition, Lilburn's harmonic<br />

rhythm conforms with traditional principles. That is to say, where<br />

points <strong>of</strong> t~nsion are located, such as in approaches to cadences, his<br />

harmonic rhythm increases.· Where points <strong>of</strong> relaxation occur, such as at .<br />

the beginning <strong>of</strong> thematic expositions, his harmonic rhythm remains static.<br />

In large-structured works, as pointed out above, the <strong>beginnings</strong> <strong>of</strong> his
