In particular using Fibonacci numbers. Iāve been interested in this since hearing a few compositions by Tool, some of their melodic pieces are created this way, also the spiral principle is observed.
This run through by Paul Davids is explanatory, very interesting!
Iām working on some ideas at the moment for relaxing background music and are looking into this idea because it is supposedly capable of giving relaxation and pleasure. In my case as I donāt sing itās easier also I donāt really see how it could be applied to lyrics.

As a help to understand some of it a review of a particular Tool song (Lateralus) by one of my subscribed channels

Hereās an interview of a composer and mathematician that teamed up to write an album. They took a different approach to each song. Pi and childrenās songs took center stage.

Have just stumbled across this thread when searching the forum for discussions on the relationship of maths to the guitar. This Paul Davids video is really enjoyable to watch and is setting off lots of ideas. Did you manage to progress any further with exploring it yourself?

Great find. Are you experimenting with incorporating any of this yourself?

Iām still a beginner but found myself noodling over number patterns at the weekend when thinking of different ways to learn notes on the fret board. Thinking of intervals reminded me of the golden ratio and the Fibonacci sequence. Then I started thinking of patterns of how one might play or write music. Next thing Iād fallen down a , all be it a happy one.

Years ago I was viewing a residential house as part of the Open House weekend in London. The home had a really grand stair case that spiralled up over several floors. The walls going up the stairs had artwork placed in sync with the Fibonacci sequence with each piece of artwork become larger as you went up. Thatās stayed with me.

@Sound_Bound, It all started for me with the book āNatureās Numbersā. Among many other things, the author shows how patterns in nature such as the spirals on a pineapple and the number of petals in a flower are related to the Fibonacci sequence.

An interior designer with a numerical mind. That would have caught my eye too. The āgolden ratioā, which architects and designers reference, comes into play here too because the ratio of two adjacent numbers in the Fibonacci sequence approach the golden ratio as the sequence increases.

I havenāt tried mixing fibonacci with guitar. My playing sounds a bit āoffā just trying to play normal stuff ;-).

One challenge might be that the underlying scales are sort of āman madeā as opposed to ānaturalā. However, it might be interesting to make up your own tunings where the frequencies of each string are fibonacci numbers. It might not be kind to our western ears, but it could be something even better (definitely weirder).

I have actually toyed with the idea of using mathematics for music myself. My thoughts come from bell ringing (specifically method ringing) which is about using unique permutations, and which has its roots in mathematical group theory.

Iām starting from the basics, at this point (because thatās really where I am with method ringing) and looking at how I could use patterns like plain hunt and plain bob in a musical context.

Iāve listened to many a bell tower ring out over the years, and I never once gave any thought to how the design or playing of it relates to āmusicā. Your post prompted a typical google search that uncovered vast amounts of info about bells, chimes, and carillons and the field of study known as campanology.

This Wikipedia article is a good starting point if you are so inclinedā¦

Thanks for your replies, I have been experimenting with variable results, to get what you really want you have to understand how to apply the method. Iāve found a few more great references to help along the way:

And

These should resolve most of the issues you may have understanding how to apply it, this is no means a complete guide but helps a lot.
One of the important things to consider is that itās not just about pitch, itās also about duration of the pitch, that was my sticking point to start with! The other important thing is that it doesnāt matter what key you work in, regardless of key you just use the intervals.
Iāve not done a complete composition yet because a few other things have taken my interest, at the moment itās a work in progress that I fit in with the rest of my projects; hopefully Bass is going to be included in the project once I get used to using it!
