<h2>IMPORTED REVISION FROM WIKISPACES</h2>
A '''goldonic series''' or '''golden series''' is a series of frequencies that form a [https://en.wikipedia.org/wiki/Geometric_progression geometric progression] whose generating interval is the [https://en.wikipedia.org/wiki/Golden_ratio golden ratio] (1.61803....).

The goldonic series is unique among geometric sequencies because only //&lt;span style="background-color: #ffffff; color: #252525; font-family: sans-serif; font-size: 14px;"&gt;φ&lt;/span&gt;// satisfies the equation //x//&lt;span style="vertical-align: super;"&gt;n-1&lt;/span&gt; //+ x//&lt;span style="vertical-align: super;"&gt;n&lt;/span&gt; //= x//&lt;span style="vertical-align: super;"&gt;n+1&lt;/span&gt;.
The goldonic series is unique among geometric sequencies because only ''<span style="background-color: #ffffff; color: #252525; font-family: sans-serif; font-size: 14px;">φ</span>'' satisfies the equation ''x''<span style="vertical-align: super;">n-1</span> ''+ x''<span style="vertical-align: super;">n</span> ''= x''<span style="vertical-align: super;">n+1</span>.


From an acoustic standpoint, the goldonic series contains some "harmonic-like" characteristics despite being inharmonic. Because each term is equal the difference between the next highest and next lowest terms, a phenomenon similar to modelocking can occur (in which each oscillator becomes entrained to the difference tone generated by its nearest-neighbors).
