Hideyuki Ezaki spent his career inside the largest musical instrument company in the world, and used it to do something no independent maker could have managed. Yamaha sent him to Spain for three years to study under two of the great Andalusian and Madrid masters. He came home, spent seven years building Yamaha's finest guitars, and produced an instrument so distinctly his own that the company's own customers stopped calling it by its model number and started calling it the Ezaki model. Then he retired — and immediately opened his own workshop to chase the sound further.

The Guitar Research Section

Ezaki joined Yamaha and was assigned to a newly created Guitar Research Section, where his work was the research and product development of handmade guitars. It is an unusual place to begin a life in lutherie: not an apprenticeship in a small workshop, but a corporate research department, with the resources of a major manufacturer behind it and a brief to understand what actually makes a guitar sound the way it does.

What he found there was humbling. He has described running directly into the difficulty of making sound — the gap between knowing how a guitar is constructed and knowing why one instrument sings while another, built to identical specifications, does not. Rather than treating that as a problem to be solved and filed away, he decided to make it his life's subject.

Three Years in Spain

To learn the essence of how the master builders created sound, Ezaki went to the country the instrument came from, and stayed for roughly three years.

He studied in Granada under Eduardo Ferrer, and in Madrid under Manuel Hernández — the latter half of the celebrated partnership behind the M. Hernández y V. Aguado label, and one of the most respected Spanish makers of the twentieth century. Ezaki has given his teacher's dates precisely, 1895 to 1975, which tells you something about how the relationship was regarded.

The Ferrer connection carries a particular resonance for anyone who knows Yamaha's history. Ferrer had been brought to Japan by Yamaha in the 1960s to advise its luthiers, work that led directly to the company's first Grand Concert models. Ezaki was, in effect, following that thread back to its source in Granada.

What he learned there was not only technique, though he did spend the long hours required to absorb traditional methods essentially unchanged in a century. He has been explicit that the more important lesson was one of attitude — the seriousness with which the Spanish masters approached the work, and the mental and spiritual dimension of making. That, he says, remains at the centre of how he builds.

The verdict came from the players. Guitars Ezaki built in the Madrid workshop were highly regarded by concert guitarists of the first rank, among them Narciso Yepes and Oscar Ghiglia — which is a remarkable thing for a visiting Japanese student to have achieved in the middle of the Spanish tradition itself.

The Ezaki Model

Back in Japan, Ezaki spent seven years responsible for building Yamaha's highest-grade guitars — the top of the range, made by hand.

Out of that period came the GC-30B. Built with the Spanish principles he had brought home and, by his own account, with his soul poured into it, the instrument expressed enough of his individual character that players began referring to it simply as the Ezaki model. It was praised for a powerful, well-balanced voice with an unmistakably Spanish scent — and it established what has since been called the Ezaki sound, taken up by guitarists and enthusiasts in Japan and abroad.

His position also placed him in conversation with the most significant guitarists of the era. As an engineer and a maker he discussed the instrument with players including Andrés Segovia and Leo Brouwer, and through Yamaha he met guitar makers, dealers and players across the world, speaking at seminars about the instrument from a builder's perspective.

2006: The Ezaki Guitar Workshop

Most people retire from a career like that. Ezaki reached the company's retirement age in 2006 and immediately founded the Ezaki Guitar Workshop, with the stated aim of pursuing the ultimate version of the sound that already bore his name.

The instruments coming out of it have been received as exactly that. The response has been that the bright, powerful, Spanish-inflected voice is back, balanced from the lowest notes to the highest — described plainly as the revival of the Ezaki sound. His experience with the guitar now runs beyond fifty years.

What the Guitars Do

Ezaki characterises his instruments in four terms, and they are worth taking at face value because they describe priorities rather than adjectives.

• A bright, transparent tone in the Spanish manner — the quality he went to Granada and Madrid to understand
• Balance across the range, from bass through the middle register to the treble, with no register dominating
• Carrying power — the ability of the sound to reach the back of a hall, which is a different property from loudness under the ear
• Accurate intonation and ease of playing — the unglamorous engineering that separates an instrument a professional will live with from one they will admire and put down

That last pair is where the Yamaha years show. A maker who spent a decade in research and development, and seven more building the top of a major manufacturer's range, has a different relationship with intonation and playability than a maker who has only ever worked alone. Those are measurable properties, and he treats them as such.

My starting point as a guitar maker is a Spanish workshop. What I learned from Manuel Hernández was the traditional technique — but more importantly the attitude and the thinking, and that remains at the centre of my work.

Beyond the Bench

Ezaki has also given his time to the guitar community around Hamamatsu, serving as chairman of the local guitar appreciation society and heading the Hamamatsu guitar ensemble Acorde — working to keep guitar music alive regionally rather than only building instruments for people elsewhere.

It fits the pattern of the career. This is a maker whose entire working life has involved transmitting something: first from Spain to a Japanese factory, then from a factory to the wider world through seminars, and now to players in his own city.

Why Ezaki Matters

• Began in Yamaha's newly established Guitar Research Section, researching and developing handmade guitars
• Studied in Spain for around three years — under Eduardo Ferrer in Granada and Manuel Hernández of M. Hernández y V. Aguado in Madrid
• Learned century-old traditional Spanish methods, and the mental discipline the masters brought to the work
• Guitars he built in the Madrid workshop were praised by Narciso Yepes and Oscar Ghiglia
• Spent seven years building Yamaha's highest-grade instruments after returning to Japan
• His GC-30B became known simply as the Ezaki model, and established the Ezaki sound
• Discussed the instrument directly with Andrés Segovia and Leo Brouwer
• Founded the Ezaki Guitar Workshop in 2006 on retirement, with more than fifty years of experience behind him

There is a persistent assumption that factory makers and artisan makers are separate species. Ezaki's career is the clearest possible argument against it. He used a corporation's resources to get an education no lone craftsman could have afforded, spent decades applying it at scale, and then — at the age when the career was formally over — took everything he had learned to a workbench of his own. The guitars he builds now are the product of both halves: Spanish tradition learned at the source, and a researcher's insistence that the things which can be measured should be got right.
