If I have a vocal arrangement which was originally written for male voices, what do I do to replace one (or more) of the male voices by a female voice?
- Do I ask the female singer to sing the exact same notes as the original male singer did? That would require an extraordinarily low female voice in some cases.
- Do I allow the female singer to sing an octave higher? This however, would change the arrangement somewhat. A voice that was originally below the main melody may end up above the melody.
Imagine an amateur band sings an Eagles song, but the band happens to have two male and one female singer. Things like this happen all the time, so I assume there must be a "best practice" answer.
