In compositions aleatoric <strong>in</strong> nature, some <strong>of</strong> <strong>the</strong> artistic choices usually made by<br />

<strong>the</strong> composer were left to chance, and <strong>the</strong>refore not a product <strong>of</strong> specified composer<br />

<strong>in</strong>tentions. Cage’s most notable composition utiliz<strong>in</strong>g this pr<strong>in</strong>ciple was Music <strong>of</strong><br />

Changes (1951) composed through use <strong>of</strong> <strong>the</strong> Ch<strong>in</strong>ese book <strong>of</strong> oracles I-Ch<strong>in</strong>g. 57 In<br />

<strong>in</strong>determ<strong>in</strong>ate music, certa<strong>in</strong> aspects <strong>of</strong> <strong>the</strong> music were also unspecified leav<strong>in</strong>g no<br />

possibilities for mistakes, as Slonimsky expla<strong>in</strong>ed:<br />

In nuclear physics, <strong>the</strong> pr<strong>in</strong>ciple <strong>of</strong> <strong>in</strong>determ<strong>in</strong>acy states that it is <strong>in</strong>herently<br />

impossible to determ<strong>in</strong>e both <strong>the</strong> position and velocity <strong>of</strong> any subatomic particle<br />

beyond <strong>the</strong> lim<strong>in</strong>al degree <strong>of</strong> accuracy. This notion has impressed some modern<br />

composers and moved <strong>the</strong>m to apply <strong>the</strong> <strong>in</strong>determ<strong>in</strong>acy pr<strong>in</strong>ciple to composition<br />

with aleatory or stochastic elements. If <strong>the</strong> position <strong>of</strong> a note is <strong>in</strong>dicated<br />

precisely, <strong>the</strong>n <strong>the</strong> rhythm must be optional, and vice-versa. The perform<strong>in</strong>g<br />

musicians are free to improvise ei<strong>the</strong>r <strong>the</strong> actual notes <strong>in</strong> <strong>the</strong> nucleus considered<br />

<strong>in</strong>determ<strong>in</strong>ate, or its rhythm, but not both.<br />

While both practices resulted <strong>in</strong> multiple consequences, <strong>the</strong> most obvious impact was felt<br />

<strong>in</strong> <strong>the</strong> realm <strong>of</strong> notation and <strong>in</strong>terpretation.<br />

Cage utilized <strong>the</strong> voice <strong>in</strong> his later compositions as a vehicle <strong>of</strong> sound, not<br />

necessarily beauty; EVTs operated on <strong>the</strong> same premise. The abnormal did not exist, nor<br />

did anyth<strong>in</strong>g non-musical; every sound had significance. Douglass Kahn stated, “After<br />

him <strong>the</strong>re is no divid<strong>in</strong>g l<strong>in</strong>e between musical sound and ord<strong>in</strong>ary sound because all<br />

sound becomes music.” 58 Cage took <strong>the</strong> opportunity to compose <strong>in</strong> such a way that both<br />

he and his audience could experience <strong>the</strong> sound <strong>of</strong> anyth<strong>in</strong>g, <strong>in</strong>clud<strong>in</strong>g silence, <strong>in</strong> its<br />

57 The I-Ch<strong>in</strong>g is an ancient Ch<strong>in</strong>ese book <strong>of</strong> philosophy that is used by some to assist <strong>in</strong> mak<strong>in</strong>g<br />

decisions. It is referred to <strong>in</strong> English as <strong>the</strong> “Book <strong>of</strong> Changes.” John Cage utilized <strong>the</strong> philosophy and<br />

methods <strong>of</strong> chance <strong>of</strong> <strong>the</strong> I-Ch<strong>in</strong>g to make artistic decisions while compos<strong>in</strong>g.<br />
