Structural tuning of classical guitar
by Tom Chalko MSc, PhD
Tuning strings is not enough.
We need to tune guitar acoustic body-resonator too...
There are essentially 2 ways of achieving
1. Generations of trial-and-error
constructions over many decades (or centuries) so that some luthiers
can build distinctively better instruments than others and demand
2. Individual structural tuning of
ready-to-play guitar, essentially taking any guitar at hand and
maximising its acoustic and performing potential
The method of individual structural tuning can improve acoustic
performance of classical/flamenco guitars of various designs and
age, from traditional and vintage guitars to modern double-tops
with exotically braced soundboards.
The key advantage of the “structural tuning” method
is that it is performed on a complete ready-to-play instrument
so that acoustic performance improvements can be directly observed
at all stages of the “structural tuning” process.
This is distinctly different from tuning (tap-testing) individual
instrument components before their assembly, introduced by Antonio
Stradivari (for violin) and Antonio de Torres (for guitar).
Design of a violin allows some structural-tuning when violin is
ready-to-play. So-called sound-post in a violin can be moved and
its position/design optimised to achieve the best acoustic response.
An equivalent option is not available for guitar.
The “structural tuning” method brings a possibility
of acoustic performance optimisation to the world of ready-to-play
