Generally found in root position,{{sfn|Benward|Saker|2009|p=179}} the [[inversion (music)|inversion]] of a complete thirteenth chord including ''all'' seven notes, itself, "a rare phenomenon",<ref name="Piston"/> is a theoretical impossibility since a new thirteenth chord with a different root is produced, for example Cmaj<sup>13</sup> (C-E-G-B-D-F-A) becomes {{Disputed inline|Talk page section|date=June 2020}} Em<sup>13{{music|b}}9</sup> (E-G-B-D-F-A-C) then G<sup>13</sup> (G-B-D-F-A-C-E), and so on, when inverted.{{sfn|Cooper|1981|p=372}}
