• World of Tuning: Home •


Everything you didn’t know you wanted to know about guitar tuning: fresh perspectives from Malagasy mythology to modern science, via jazz, Joni, Jimi, and more! (Open-access, ad-free resources)

[under construction: out 2022!]

Despite being a universal guitaristic experience, tuning rarely gets the attention it deserves. Few instruments give more freedom to choose a ‘starting canvas’: unlike a piano, horn, or drum, the guitar can move fluidly between tunings, opening up fresh geometries and spaces of the imagination at every turn. Many facets of learning are unique to these zones…

The ‘World of Tuning’ explores how we can get the most out of our peg-twisting rituals. Stemming from my Guitar World lesson series, the project explores new tuning horizons from multiple musical angles: practical, harmonic, historic, social, scientific, spiritual, and so forth. We take a global view, incorporating ideas from a worldwide variety of stringed traditions – India, Mali, Hawaii, Madagascar, Indonesia, and beyond…

Everything here will stay perpetually open-access and 100% ad-free. Mainly, I hope these pages will bring creative joy, and catalyse fresh questioning around what we – and the guitar – are truly capable of.


How can we best utilise our tune-up time? Why don’t we choose our starting notes as we do our chords? What can we find in the guitar’s under-explored microtonal capabilities? And which global traditions offer unique insights?
