'''145/144''' or the '''29th-partial chroma''' is a [[superparticular]] interval of about 12.0 [[¢]]. It is the difference between [[29/16]] and [[9/5]].
'''145/144''', the '''adeonisma''' is a [[small comma|small]] [[29-limit]] [[superparticular]] [[comma]] of about 12.0 [[¢]]. It is the difference between [[29/16]] and [[9/5]] and between [[29/12]] and [[12/5]].


In [[Ben Johnston's notation]], it is denoted with "29", while its reciprocal is denoted as <span style="display: inline-block; transform: rotate(180deg)">29</span> (a turned 29).
This interval is the 29th-partial chroma (29-limit formal comma) in [[Ben Johnston's notation]], denoted with "29", while its reciprocal is denoted as <span style="display: inline-block; transform: rotate(180deg)">29</span> (a turned 29). If the base note is C, then 29/16 is represented by C–Bb29.
 
== Temperaments ==
Tempering out this comma in the 29-limit leads to the '''adeonismic temperament'''. Equal temperaments which temper out this comma include {{Optimal ET sequence|7, 10, 12, 15, 19, 22, 26, 34, 41 and 53}}.
