My good friend John Buckman has written an article (part one) on recording keyboard instruments. John does this professionally, so the advice is from extensive experience.

This article is aimed at harpsichordists, but many of the same issues are true for other types of keyboard instruments, and many of the points raised are equally applicable to any kind of recording, professional or domestic.

Article (part one of the series) can be found in the British Harpsichord Society periodical Sounding Board, at:

pages 23-26

I'll post any further instalments when they come.

Thank you very, very much for posting this link, Wild Rose. I haven't yet read your article about recording, although I will, but several others which are very interesting. Thanks again.

not necessarily wild.. brilliant eglantine thanks should be a fine and informative read, many many folk are always asking for info of this nature.
