Jonathan Powell ‒ Pianist 
Dear Mister Powell,
I really enjoyed your performance of Arnold Bax’s Quintet on youtube !
I would really love to play this piece but I cannot find the score/publisher.
Would you be so kind to help me find it ?
Warmest regards,
Lionel Bams
Hi. It was published in London in the 1920s by Murdoch and Murdoch. I’m sure this company doesn’t exist any more. There’s a copy in the library of the Royal Academy of Music in London, but I don’t know how helpful that is.
Mr. Powell, I have question: After reading http://www.foxall.com.au/users/mje/OpusClav.htm, I got a hold of the J.Curwen and Sons edition of Opus Clavicembalitisticum I tried playing a few passages and was shocked by how many errors there were in just the notes alone. Are these errors only in this edition or does the manuscript also contain numerous errors (or at least what can be called an error). What edition did you use to play the piece?
Hi. I used a mixture of the published score and the ms. There is also a published score with some of the composer’s corrections in it. I also re-typeset parts. Hope this helps.
