Showing the same articulation above and below a note or chord
By default, LilyPond does not allow the same articulation (e.g., an accent, a fermata, a flageolet,
etc.) to be displayed above and below a note. For example, c4 \fermata^\fermata will only
show a fermata below. The fermata above will simply be ignored. However, one can stick scripts
(just like fingerings) inside a chord, which means it is possible to have as many articulations as
desired. This approach has the advantage that it ignores the stem and positions the articulation
relative to the note head. This can be seen in the case of the flageolets in the snippet. To
mimic the behaviour of scripts outside a chord, ’add-stem-support would be required. So,
the solution is to write the note as a chord and add the articulations inside the . The
direction will always be above, but one can tweak this via a \tweak: 4^\smallFlageolet_\smallFlageolet

String number extender lines
Make an extender line for string number indications, showing that a series of notes is supposed
to be played all on the same string.
