The Temperament of Keyboard Music

The last remaining stock of books „The Temperament of Keyboard Music“ by the author Alexander Mackenzie of Ord is offered. The books are from the estate of the author being likely new only with some storage tracks.

The whole book, including two Audio CDs with recordings being discussed in the book, is about different tuning and pitches in ancient music. The blurb writes the following: 

"This new book is a radical reappraisal of the whole science of keyboard tuning. Its fundamental feature is a complete revision of the terminology currently in use, since this frequently is not only confusing but also can be conflicting, as well as being inaccurate.

"From this essential foundation, the individual construction of the different tuning and temperaments can be clearly understood, and their essential contribution to the interpretation and enjoyment of keyboard music the better appreciated. Their historical development is also outlined, much invaluable detail being filled in by various contemporaneous comments and remarks of the period concerned, without which this study would not only become relatively tedious, but also far less interesting and valuable. The author’s debt of gratitude to these generally unheard voices of the past is immeasurable.

"It is sincerely hoped that, collectively, the matters here covered will furnish readers with all the necessary information which will enable them to come to their own conclusions about this most vital, but usually obscure, component of the great art of music."

RRP £75

The books are located in Germany. The price is 35€/£30 additional postage (postage within EU to UK £4,50).

The Zumpe & Buntebart Piano of the

Museu de la Musica de Barcelona

This is the first book solely devoted to Zumpe and Buntebart, and is written around one piano in particular.  Unusually, it has three authors, Pablo Gomez Abalos (historian and pianist), Michael Cole (technical expert and historian), and Kerstin Schwarz (restorer).

The book begins with an introduction by Marisa Ruiz Magaldi (museum curator) to the 1776 piano in the Museu de la Musica de Barcelona.


A section by Michael Cole, the well-known restorer, maker, and historian, deals with the historical context of the small piano in London.  The importance of Johannes Zumpe’s experience with the ‘English Guittar’ and Gabriel Buntebart’s royal connections are discussed.  We remember that Zumpe’s workshop was ‘at the sign of the Golden Guittar’.   Michael also discusses the materials used in these instruments, and their construction.  There is also a short section on ‘Organised Pianos’ – combinations of these early instruments with a small organ.


Pablo Gomez Abalos deals with the early piano from the point of view of the keyboard.  This section explores the characteristics of the ‘single action’, and the importance of setting it up correctly.  This is a topic of great importance to all of us interested in early pianos, and it needs further discussion.


The eminent restorer Kerstin Schwarz gives full coverage of the ethical considerations behind the decision to go ahead, and the restoration itself. 


Pablo is a skilled player, and demonstrates these early instruments at their very best.  We look forward to recordings on the 1776 piano, but in the meantime please listen to his performance of the CPE Bach Rondo in C minor in which he demonstrates the variety of colour achievable through the use of the handstops.  This is performed on a 1777 Zumpe & Buntebart, restored by Andy Durand.


1777 Zumpe


The 274-page book is copiously illustrated, and will take its place as a standard work on the early evolution of the square piano, and the importance of Zumpe and Buntebart in particular.

The Colt Collection - Original Catalogues

Amongst the lots in the sale of the Colt Collection were the remaining stocks of the two booklets about the instruments, published in 1969 and 1981.  Why the second of these, 1944 - 1981 is called the 'Golden Jubilee' edition remains a mystery to me!  Do please let me know if you have any ideas.

  Anyway, our friend Luke Bradley was the successful bidder for the remaining stocks, and he now offers these for sale at £5 each or £10 for the two.  Postage and packing (the same for one or two) will be £3.00 UK, £5.50 Europe, £6.50 World.  Please contact Luke

The Colt Collection -

The 'Missing' Instruments 

At the final viewing of the Colt Collection, some of us had the feeling that we had not seen some of the instruments before.  Indeed, it was widely known that at various times some instruments had been on loan to museums in Germany or Switzerland.  

  Sabine Klaus made a study of seventeen instruments which were on loan to the Stadtmuseum in Munich, and wrote a book about these.  Copies are now available at the very reasonable price of €6 or £5, plus postage from Germany.

Please note that the book is in German.  If you would like a copy, please contact Sabine

Michael Hannon has written a very entertaining and informative book tracing the history and restoration of 'Mrs Findlay's Broadwood Square Piano'.  The book includes a CD recording of the piano.
