With a firm belief that the dissemination of knowledge is more critical than following the historical precedent of only posting in established journals, I offer this space for organological studies by those who would care to make use of it. We will remain a little more formal here than in the Restoration Reports, and other instruments besides square pianos are fair game for publishing! Perhaps in time this will all morph into something like “Early Piano Tech” but for now we will use this space and see if interest grows. I will also repost selected articles that have made it onto the web already, as a gathering spot for this information.

July 26, 2013 – Margaret Debenham now has her aricle on William Southwell posted, and the link can be found here:

We have followed up with an explaination of Southwell’s inventions, which I hope you will find as auxillary to Michael Cole’s descriptions found as a link in Debenham’s text.
