Fibonacci Add-On Set STD

Product Information


There are 8 Fibonacci Forks in the complete set, represented by the ratios derived in the Fibonacci number sequence. The sequence starts with 1, and continues with (1+1)= 2, (2+1)= 3, (3+2)= 5, (5+3)= 8, and so on. The last two numbers in the sequence combine to produce the next number... 1, 1, 2, 3, 5, 8, 13, 21, 34, etc. The first Fibonacci tuning fork is labeled 1/1, followed by 2/1, 3/2, 5/3, 8/5, 13/8, 21/13, and 34/21. Spiraling Intervals are created by using the reference fork (1/1) in combination with any other Fibonacci ratio fork. For example, to create the interval 8/5 use the 8/5 tuning fork with the 1/1 tuning fork. It is also possible to use two or more of any of the tuning forks in the set to create micro partial intervals.

If you already own the STD Harmonic Spectrum Set, it contains 4 of the 8 Fibonacci Forks: C-256 (1/1), C-512 (2/1), G-384 (3/2), and A-426.7 (5/3). With the addition of these 4 Add-On forks 8/5, 13/8, 21/13, and 34/21, you can make a complete Fibonacci Set.
