== JI interpretations ==
Interpretations as a [[just intonation]] chord.

<!-- ''The only interpretations allowed in this section are ones where all 'intervals from root' 
''have a denominator of 8 or less (to prevent the section becoming too long).'' -->

=== 5-limit ===
{{Infobox Chord|10:20:25:36:40:48|ColorName=yo gu-7 guqu-9 no-5 or y,g7gq9no5|Root=20}}

This chord appears in [[20afdo]] and all higher [[AFDO]]s.

According to this interpretation, the 12edo hendrix chord has 30.2 [[cents]] of total error and no more than 17.6 cents error on any single interval.

[[EDO]]s with less than 20 cents error on any one interval include: {{EDOs|12, 15, 18, 19, 22, 24, 26, 27, 28...}} and everything bigger than 28.

=== 19-limit ===
{{Infobox Chord|4:8:10:14:16:19|ColorName=har-7 noqu-9 no-5 or h7,19oq9no5|Root=8}}
In the [[19-limit]] it may be tuned as '''4:8:10:14:16:19''', an extended [[4:5:6:7|harmonic seventh chord]].

This chord appears in [[8afdo]] and all higher [[AFDO]]s.

[[EDO]]s with less than 35 cents error on any one interval include: {{EDOs|12, 15, 16, 17...}} and everything bigger than 17.

== Tempered interpretations ==
Interpretations as a [[temperament|tempered]] chord.

=== Essentially tempered ===
It can also be tuned as an [[essentially tempered chord]] that splits the difference between the [[19/16|19/8]] 10th and the [[7/3]] 10th. 

This chord tempers out the ''hendrix comma'' of [[57/56]]. 

[[EDO]]s including this chord are {{EDOs|9, 10, 12, 14, 16, 17, 21, 22, 26, and 31}}.
