"Music - Golden Ratio & Fibonacci Sequence - Part 3"

गटावरील संगीतप्रेमींसाठी(मनजीत,उदय,टोपी,दीप्या,जया इ.) "गाणी कशी तयार होतात" अशी एक नवीन लेखमाला सुरू करीत आहे.टोपीची अवघड "संगीत कोडी" सोडवायला त्याची मदत होते का पहा ! या लेखात गाणे "सुश्राव्य" का होते त्याचे रहस्य सांगतो.त्यासाठी "Golden Ratio" व "Fibonacci Sequence" या नावाने सध्या ओळखल्या जाणार्‍या पण मूळच्या हजारो वर्षांपूर्वींच्या भारतीय "ऋषी पिंगला व ब्रह्मदत्त" यांनी शोधून काढलेल्या वैदीक गणीतीय संकल्पना समजायला हव्या.जया,टोपी व सुनीलच्या सहज लक्षात येतील.बाकीच्यांना थोडे कष्ट करावे लागतील.वाचा.

1.In "Fibonacci Sequence" succession works when every new number is the result of adding the two previous ones: 1, 1, 2, 3, 5, 8, 13, 21, etc.

2.At the same time, the "golden number(also known as Phi, represented by the Greek letter Φ)" is a concrete point that we find between the proportions of two segments on a straight line:

•——————————•——————•

A                                                              F                                       B

Where F is the Φ equivalent to “1,6180339885…”, which is also known as the golden number.

3.This is an endless and irrational figure that does not represent a periodic repetition. 4.Based on this basic scheme,we can define what we want to compose.

5.If our song lasts from A to B, then the element F would be the modifier of the track’s rhythm in the following manner.

6.We divide our work into two parts, which will be defined by 61.8% and 38.2%, in accordance with the golden ratio.

7.Afterwards, these will be multiplied by “x”, where x represents the length of the work. Putting it into practice makes it even easier: if your song lasts 4 minutes (240 seconds), then:

240s*0.618Φ = 148.32s or, at 2 minutes with 48 seconds we must intercept the work with a change, a bridge, an arrangement with a different instrument or a new melodic composition.I have explained this in my earlier various article series.

8.Now, using the "Fibonacci sequence", we can also create embellishments and changes in the rhythm of our song to make it all the more attractive, where the sequence 1, 1, 2, 3, 5, 8, 13, 21… will correspond to the minutes or seconds when we will make changes in the tone that implies emphasizing the note that is played at that moment.
