A notation for rodan can be devised by identifying what is common in 41edo and 46edo. Below is one using [[circle-of-fifths notation]] with an additional module of arrow accidentals to represent the syntonic~septimal comma. This notation looks exactly like that for [[cassandra]], but it is peculiar to rodan that three comma steps make up a diatonic semitone, and thus the slendric tetrad (1-8/7-21/16-3/2) on C is C-^D-vF-G, for example. | |||
