'3 or 5 of 10 for 4' is a quartet for 4 instruments. As the title page
suggests the composition is primarily for recorders, but other wind
instruments may be used. As matter of fact at the performance in 1970
the instruments used were flute, clarinet, french horn and bassoon.

The title refers to subsets of 3 or 5 elements of sets consisting of 10
different notes beeing played by 4 musicians. The tone set of each section
is a 10 note chromatically consecutive subset of the full 12 note set.
Each 10 note subset starts a whole not above the previous subset. Exactly 6
different subsets can made corresponding to the 6 sections of the
composition.

Besides making the score publically available my aim has been to examplify
how contemporary music making use of 'unconventional' notation methods may
be typeset with MusiXTeX and it's preprocessors pmx and mtx.

Each of the 6 sections have been typeset in separate mtx source files -
relying more or less on a common set of MusiXTeX macros (macros.tex). The
tex files resulting from the processing of the mtx sources are linked
together into the final score by a header script 3or5.tex links.

English comments on how to interprete the notes are found at appropriate
places in the score, whereas german, french and danish translations of the
comments are appended to the score.

I want to thank Werner Icking and Don Simons for their generous continued
help on solving numerous MusiXTeX-nical problems during the typesetting.

Jean-Pierre Coulon has provided the french translation of the playing
instructions, my father Georg Mondrup the italian translation and Werner
Icking has seen to it that my drafts of a german translation ended up as
decent german.
