Dear Sir,

The Groupe de Recherches Musicales of the O.R.J.F. in
Paris, is preparing a new, more complete and up=todate edition
of the documentation on tape music that was published in 1962
as the "R?pertoire International des Musiques Exp?rimentales",
This work will be coordinated by Mr. Hugh Davies, and will be
either published commercially, or duplicated, and available to
interested persons on request: if the latter, in February 1967. .

In order to unify the final presentation of details,
and to speed up the completion nf the documentetion, we are
sending you a list together with this letter, whish contains
all information we have on compositions produced in your stu-
dio, in more or less the form in which the final document will
be publishede

In this new edition it is hoped to include all compo-
itions for magnetic tape ever composed (electronic music, mu-
ique concr?te, etc.), up to the end of 1966, With the rapidly

increasing spread of tape music throughout the whole world, and
its acceptance and integration into the field of contemporary
music, it appears that a complete documentation will never again
be possible, and, it is hoped, no longer necessary in the futu-=
ree In many of the lists that are being sent to studios for
corrections and additions, works are listed that do not appear
in official lists of the studios - such as those published in
the original "R?pertoire" - but have bsen mentioned in athex
sources, Since they give a wider and more comprehensive picture
of the output of a studio, we ask you to list absolutely every-
thing! This includes works performed but later withdrawn, exe
perimental studies - particularly by well-known, sometimes un=
expected composers = that have not been released, and so on.

O.R.T.F. - 116. AVENUE DU PRESIDENT-KENNEDY - PARIS-16? - TEL. : 224-22-22 - R. C.: 59B5498 - INS.E.E.: 861 75 1169003

The estimation of the total number of compositions
that will be included in this document is that it will almost
certainly exceed 3,000... Some interesting and previously un-
published details of the early history of tape music in various
countries are coming to light.

In this new document we are aiming at a complete pictu-~
re of tape music, and not restricting ourselves to officially
sponsored studios, We are also concentrating on defining the
function of each work more precisely, and listing all works in
a chronological order, Methods of distribution (records, tapes,
scores) will be given in greater detail, On the other Hand, we
are omitting the lists of studio equipment and the bibliography
of the original "R?pertoire",

! Please send your completed list and any other items
