Define substitution function accOne() as:
accOne =
#(define-music-function
(x )
(ly:music?)
#{
$x8 $x8 $x8 $x8 $x8
#})
Call accOne() with:
\accOne f
Expected output is:
f8 f8 f8 f8 f8
However, lilypond reports error as follows:

Interpreting music...
How to tell lilypond to look for variable "x" and make a 1/8 note out of it,
instead of looking for variable "x8"?
Simply insert a space between "x" and "8". Best, Jean
