fifth

Another extension of strict organum is 'fifthing'. Fifthing is a note-against- note method of creating a two-part texture by improvising a second voice over the given tune, starting and ending each musical phrase at the octave and proceeding mainly in fifths above the tune at others times.

3/5 has been through fifthing. 2/3 has been through thirding. Therefore, 3/5 now needs thirding and 2/3 needs fifthing
