Original Wikitext content:

**Das Goldene Tonsystem** als Fundament der Theoretischen Akustik

...is a book of the danish music theoretician (music reformer and visionary) Thorvald Kornerup. [http://d-nb.info/361092458] written in German.

The system is based on the paradigm that the relation between whole and half tone intervals should be the [[http://en.wikipedia.org/wiki/Golden_ratio|Golden Ratio]]

[[math]]
\varphi = \frac 1 2 (\sqrt{5}+1) \approx 1.61803\,39887\ldots\,
[[math]]

Thus some edo systems - the 12-step too - could be considered as approximations to this ideal.

== Construction ==
If you use two neighboring numbers from Fibonacci Series 1 1 2 3 5 8 13... you get the following approximations:
 1, 1 -> [[7edo]]
 1, 2 -> [[12edo]]
 2, 3 -> [[19edo]]
 3, 5 -> [[31edo]]
 5, 8 -> [[50edo]]

== Listening ==

[[http://www.io.com/~hmiller/midi/canon-golden.mid|An acoustic experience]] - Kornerup himself had no chance to have it - is contained in the [[Warped canon]] collection.
