833 cents scale
The 833 cents scale is a musical tuning and scale proposed by Heinz Bohlen based on combination tones, an interval of 833.09 cents, and, coincidentally, the Fibonacci sequence. The golden ratio is φ = 1 + 5 2 = 1.6180339887 … {\textstyle \varphi ={\frac {1+{\sqrt {5}}}{2}}=1.6180339887\ldots } , which as a musical interval is 833.09 cents ().
