Fibonacci number examples11/30/2023 Pluck a string on a guitar, however, and search for the harmonics by lightly touching the string without making it touch the frets and you will find pure Fibonacci relationships. In practice, pianos are tuned to a “tempered” frequency, a man-made adaptation devised to provide improved tonality when playing in various keys. The calculated frequency above starts with A440 and applies the Fibonacci relationships. This creates the Fibonacci ratios of 1:1, 2:3, 3:5, 5:8 and 8:13: The Fibonacci numbers, in red on both scales, fall on the same keys in both methods (C, D, E, G and C). Next, number the 13 notes of the chromatic scale. Here’s another view of the Fibonacci relationship presented by Gerben Schwab in his YouTube video. First, number the 8 notes of the octave scale. This is analogous to the “A is to B as B is to C” basis for the golden section, or in this case “D is to A as A is to E.” What’s more, the typical three chord song in the key of A is made up of A, its Fibonacci & phi partner E, and D, to which A bears the same relationship as E does to A. This provides an added instance of Fibonacci numbers in key musical relationships. In a scale, the dominant note is the 5th note of the major scale, which is also the 8th note of all 13 notes that comprise the octave. The word “octave” comes from the Latin word for 8, referring to the eight tones of the complete musical scale, which in the key of C are C-D-E-F-G-A-B-C. Note too how the piano keyboard scale of C to C above of 13 keys has 8 white keys and 5 black keys, split into groups of 3 and 2.While some might “note” that there are only 12 “notes” in the scale, if you don’t have a root and octave, a start and an end, you have no means of calculating the gradations in between, so this 13th note as the octave is essential to computing the frequencies of the other notes. are based on a tone which are combination of 2 steps and 1 step from the root tone, that is the 1st note of the scale.5th and 3rd notes create the basic foundation of all chords, and.A scale is composed of 8 notes, of which the.There are 13 notes in the span of any note through its octave.Even music has a foundation in the series, as: The Fibonacci series appears in the foundation of aspects of art, beauty and life. Musical scales are related to Fibonacci numbers.
