The issue is not \relative, per se. I wish people would stop maligning
it. Although I'm sure this commentary is all in good fun.
The issue is not using it correctly.
All you need to do to prevent mishaps is to start each distinct segment
with a new \relative.
At the minimum, just wrap the new voice in its own \relative.
Which takes that segment out of the scope of the rest of the enclosed
\relative and does not disturb the first voice.
\new Staff \relative a' {
a a a
<<
{ \voiceOne a a a }
\new Voice \voiceTwo \relative a' { e b b }
>>
\oneVoice a a a
}
\addlyrics { \repeat unfold 10 test }
For maximal protection, especially if you ever cut & paste things and move
them to new contexts, or are composing and change things around, it helps
to be explicit about each segment:
\new Staff {
\relative a' { a a a }
<<
\relative a' { \voiceOne a a a }
\new Voice \voiceTwo \relative a' { e b b }
>>
\oneVoice \relative a' { a a a }
}
\addlyrics { \repeat unfold 10 test }
