is, in a sense, trying to mimic, or
composers origination. But certain composers create music intending the performer to
interpret the 'original communication' as though the performance of it was indeed the
instrumentalist's 'original communication'.
Perhaps this interpretation, or 'artistic license',
may make a piece of music much more interesting. Perhaps certain listeners would prefer to
hear that quality about the music more than any other. In this case, the performer uses
the "carrier wave" of the composer's
origination to add his or her "characteristics";
without "taking-away" from the value of the "original communication".
