Whoa! What is this magic you're doing Master Moser??

- I made sure that the bf4. on "days" stays in the voice called melody. There are various ways to do this; I chose a "modern" way using \voices and \\ inside << >> which allows to automatically add a "second" voice

This is a technique completely unknown to me! It is much more simple than the

%%%%

<< 
{ \voiceOne } 
   \new Voice { \voiceTwo { 
   }} 
>> \oneVoice 

%%%%

coding that I have long used.

Much thanks!!

Thanks and credit are due to Master :-) Kastrup (in a series of commits from 2017), but unfortunately, the documentation of \voices in https://lilypond.org/doc/v2.23/Documentation/notation/multiple-voices.html doesn't show all its possibilities. A good explanation is in the docstring to be found at https://lilypond.org/doc/v2.22/Documentation/notation/available-music-functions:

      The inconspicuous "... or symbols (indicating voice names)" is
      very powerful.
