Indicators Indicator 1: original or arrangement Indicator 2: alternative medium of performance (also possible to indicate alternative for an individual medium using code c in $b to $f position 8) Notes on field contents The order and occurrence of subfields is to some extent mandatory: at least one subfield $c or $d is mandatory if field is present; a subfield $b may occur only if at least one subfield $c or $d is entered; a subfield $e may occur only if at least one subfield $d is entered; a subfield $e may immediately follow only a subfield $d, $e or $f; a subfield $f may occur only if at least one subfield $c or $e is entered; a subfield $f may immediately follow only a subfield $c, $e or $f.

15 Medium of Further Questions Medium of : Property of Work? of Expression? of what? Need to re examine definitions in the rules Does popular music have medium of performance? What is the primary artifact to compare alternatives against? Alternatives: Deliberate, incidental, or accidental? What are the proper relationships between versions? Version of? Arrangement of? Derivative of? Reduction of? /Vocal score of? Realized figured bass of? What about song versions with slightly/very different words? How finely do we want to draw the distinctions?
