Dear Werner,
you find attached 8 files: one .txt file containing seven
documentation entries and seven .ly files for each entry.
I tried to make examples for each different situation concerning
glissando one can find in (contemporary) music.
I "inspired" myself to other similar snippet in the Notation Reference
and I used two snippets found in the regression tests.
Please, feel free to change interpolate or ignore anything... and do
not hesitate to contact me again if you need.
Regards, TG

#1 ENTRY
***************************************************************************
A _glissando_ is created by attaching \glissando to a note
EXAMPLE #1
#2 ENTRY
***************************************************************************
The duration of a glissando can be splitted to place an expression mark at a
certain point, which is indicated by a stem without notehead. This can be
easily achieved in Lilypond inserting one note between the two endpoints of a
glissando. The command:
\override NoteColumn #'glissando-skip = ##t
prevents the glissando to stop at the inserted note, whose notehead can be then
hidden with
\override NoteHead #'transparent = ##t
EXAMPLE #2
If the stem doesn't align well with the glissando, it may need repositioning.
#3 ENTRY
***************************************************************************
The same command can be used when a glissando starts and/or ends on the
subdivision of a beat to specify the duration of the glissando in relation to
the beats
EXAMPLE #3
#4 ENTRY
***************************************************************************
A glissando can occur across different bars
EXAMPLE #4
#5 ENTRY
***************************************************************************
The following command allows to break a glissando when it occurres over a line
break
\override Glissando #'breakable = ##t
EXAMPLE #5
#6 ENTRY
***************************************************************************
A glissando line can connect also notes across staves.
EXAMPLE #6
#7 ENTRY
***************************************************************************
A glissando can occur between chords or between a chord and one note.
EXAMPLE #7
