Information on early pianos

This is an information service for restorers, players, owners, amateurs and researchers into Pianos built BEFORE 1837 and similar important historical instruments.

The main reason for this website it to publish the Register of Extant Broadwood Grands and provide some information about research and conservation of early stringed keyboards.

This site is constantly updated as we receive information. Many thanks to David Hunt who started and maintained this site for years.

Offers, or requests of information about Broadwood Grand pianos built BEFORE 1837 can be forwarded via email to:

Artifacts in Use. The paradox of restoration and the conservation of organs.John R, Watson, OHS Press in assoc. with Colonial Williamsburg. Don't be fooled by the mention of organs, all the principles of this book apply to any early keyboard. If you intend to restore an instrument, you should know the ethical (and some technical) problems that are involved. From the back of the book: 'Some historical astifacts are best preserved behind glass in museum exhibits, but what about objects that only reveal their full meaning through use? Artifacts in Use merges the goals of conventional restoration with the values, sensibilities, and methods of restorative conservation to describe a holistic form of preservation.'

Abate Wood in Rome: the ingegnosissimo mattematico who made the first pianoforte ‘that was brought to England’.

Patrizio Barbieri

Early Music, Volume 46, Issue 3, August 2018, Pages 501–516. I started my own investigation on Father Wood, as I would not believe he was an invention of Charles Burney, so I thought I will start with any institution In Rome that may have had links to England. I came across the Venerable English College in Rome, so I contacted the archivist, who kindly confirmed that Father Wood and his brother were students there. He provided me with a copy of the register, but he also told me that Patrizio Barbieri already did that research. I found it fascinating (as most of his other publications) and therefore I recommend it here. Louis or Lewis Wood was born at the Jacobite court in exile at Saint-Germain-en-Laye, France, on 11 November 1709, and died at Frascati, near Rome, on 23 June 1755. His father, Laurence Wood, was the doctor to James II in exile. C. Hernandez.

The Keyboard Stringing Guide, Jean Louchet. edited by Available through Amazon. This guide is a very complete resource for those who want to know and understand the nitty-gritty of stringing. Starts with more or less easy explanations but at some point it goes into hard maths and physics calculations. There are some bugs, like some decimal commas instead of points and a few other minor typos in the formulas but nothing that can confuse a physicist.


Strings. Interpreting wire gauges, by Paul Poletti. One of my favourite researchers who has brought light into the rather obscure topic of stringing. We highly recommend any of his publications.

The Art of Tuning. A self-Guided Manual for Piano Tuning, Design, Action Regulation, and Repair from mid-19th-Century France by Claude Montal. Translated by Fred Sturm, RPT. The original text of the book written by Montal (the father of piano tuning for blind people) in 1836 with the updates of 1865.

A Treatise on the Art of Pianoforte Construction, by Samuel Wolfenden. Published by Hecksher & Co. Reprinted by photolitho from the original edition of 1916 together with the supplement of 1927.

Contemporary Theory of Conservation. Salvador Muñoz Viñas. Edited by Routledge. I recommend this to anyone who wants to acquire a solid base in conservation theory, or to update their principles to the 21st century. Everything is questioned in the book, including - believe it or not, and with good reasoning - the principle of reversibility.

Piano, by David Crombie. A Photographic History of the World's Most Celebrated Instrument. Published by Miller Freeman Books. In this book you will find a history of its devolpment and numerous atypical pianos.

Ruckers, by Grant O'Brien. Published by Cambridge University Press. Though this book is devoted to the harpsichords and virginals built by the famous Ruckers family, the insights, approach to study, etc. are relevant to any person interested in early keyboards. O'Briens contribution to the study and research of pre-19th Century stringed keyboards are capital for the understanding of the pianofortes.

The Finchcocks Charity. Apart of being the keeper of the Richard Burnett Heritage Collection of Early Keyboards, the charity activities include concerts and allow the use of the instruments for research. Every year we have a number of PhD students for that purpose. Also, the charity is probably the only institution in the country that can help individuals to be trained as early keyboard technicians. This is done by different ways of founding workshop experience with top restorers and by supplying master classes in a one-to-one basis with recognised technicians. Please send your enquiries to or to myself at

Lucy Coad: - Restoration, parts, hire, etc.(Lucy has been my mentor, teacher and friend and is probably the most regarded specialist on square pianos in the world).

Friends of Square Pianos - Website of news , resources, sales, etc. Plenty of information and advice coordinated by legendary instrument maker and restorer David Hackett (one of the people I respect the most).  He also organises a yearly meeting where all the enthusiasts of early keyboard gather around instruments, presentations, etc. in a very friendly atmosphere. If you live in Europe you shouldn't miss this event (usually in April). - History of piano in general. Probably the biggest archive of piano history in the world, compiled by Bill Kibby. You will find very useful and interesting information that you won't find elsewhere. Recently he obtained permission from the queen herself to copy related historical documents from Windsor. He has also a collection of pianos arranged in a timeline with relevant information. He is actively looking for sponsors to house and maintain the collection in Burwell, Lincolnshire, UK. (Bill has collected this enormous amount of information and pianos on his own).

Valuation of early keyboards.

This is a difficult matter as some instruments are unique and some other were mass produced. Some were kept in good conditions and some other were neglected. I find there are very few rules of thumb for valuation and probably this is the reason why so few people do it. Auction houses may provide estimates but sometimes the final price could be far from the predicted. As with most antiques, the scarcity and condition is the most important points to consider. Another point is the presence of working original parts, specially leather hammer covers and soundboards. A cracked but original soundboard would be preferred to a modern replacement by an experienced restorer. In the case of pianos, squares of about 1810 - 1815 start to be less sought after than previous ones. Those made in the 1820s and 1830s are the most common and often you can find them for free, usually unrestored or badly restored, but sometimes you can get a playable one whose owners are looking for someone sympathetic to have them for free. If bought, the price is usually less than five hundred pounds. Any money spent in their restoration will never be payed back if you want to sell the instrument, most certainly. A typical restoration, so to speak, could range from three to five thousands pounds in UK. A playable instrument usually can be found for much less. If you want to find out if what you have could be valuable, you can see the archives of auction houses (online), or send us a few photographs. We don't give valuations but we could say if the instrument has some potential interest to someone.

Grand pianos are better valued and we give the same advice: look online and/or talk to collectors. And have always as much details as you can, like make, serial number, date, compass, a list of broken or missing parts (like the pedal[s]), if it looks like it has been restored in the last 50 years, etc. If you want to submit photos, take one overall shot, then details of the hammers, dampers, soundboard, nameboard and tuning pins, and try to use a high resolution, as it may be necessary to check some details.

"I have an old square piano, what can I do with it?"

This section is under development. In the meanwhile, you can write to us if you have such a query, but for the moment, I can say that the main resource for buying/selling square pianos (and really any early keyboard) is Friends of Square Pianos (


About us:

This page was created by David Hunt who after easing into retirement kindly passed it on to me, Cesar Hernandez (currently conservator of the Finchcocks Charity and an independent early keyboard technician). D. Hunt's registry of Broadwood grand pianofortes was a tremendous task and he made it available to the general public as a free source of information. It is in that spirit that we now take over and will try to add some other useful information.

The main purpose of the site is to offer all kind of information related to early fortepianos (and early keyboards in general), especially the one that is needed for conservation. As now there are no organised programs to acquire the knowledge and skills required to keep these instruments in acceptable conditions, we will try to offer (in the near future and as time permits) some resources in the form of text, documents and videos. If there is any specific topic that you would like to know about, please write to me an email: cesarherz.(at) (please substitute the (at) for the @ symbol.

Other purposes of this page are to offer some sources of historical information for researchers, and to help the community of early pianos enthusiasts to get in touch to share their passion. Any contributions toward these aims will be very appreciated.
