GoKawiilOughtred Society book links guitar fret spacing to slide rule logarithms
A newly acquired book titled 'Calculating with Tones: The Logarithmic Logic of Music,' published by the Oughtred Society, features a cover comparing the irregular spacing of guitar frets to the tick marks on a logarithmic slide rule. The book, discussed on page 34, explains how frets are placed along a guitar neck to locate musical notes, drawing a visual parallel to how slide rule scales are constructed using logarithmic principles.
GoKawiil's interpretation of the reporting above, not reported fact.
The comparison highlights a lesser-known intersection between music theory and mathematics, showing how logarithmic relationships underpin both our perception of pitch and historical calculating tools. It's a reminder that mathematical concepts developed centuries ago for computation still echo in how we understand natural and artistic phenomena today.
- The Oughtred Society, dedicated to slide rule history, published a book connecting guitar fret spacing to logarithmic scales.
- Guitar frets and slide rule tick marks both rely on logarithmic spacing principles, though not for identical purposes.
- The book's cover and content explore how logarithms shape both mathematical tools and musical structure.
Concise Model 300 Circular Slide Rule — If reading about Oughtred's logarithmic invention makes you want to slide the scales yourself, Concise still manufactures pocket circular slide rules in Japan. It's a tactile way to see how logarithms turn multiplication into addition crisp scales, no batteries, and small enough to keep next to your guitar while you ponder fret spacing.
