I have a simple song for which I know two melodies to play. They are not played simultaneously - one has to choose between one of them.
What is the common/standard notation for that?
As far as I know, a piece of music where two melodies are played simultaneously (by different instruments) is written like this:
So how would it look like (in standard notation) if the two melodies are alternatives, not both part of the music?
And if both melodies have a name (e.g. "Foo's version" and "Bar's version" named after the two componists Foo and Bar), where would these names be written?
