Among [[guitar tunings]], '''all-fifths tuning''' refers to the set of tunings in which each [[interval (music)|interval]] between consecutive [[open string (music)|open string]]s is a [[perfect&nbsp;fifth]]. All-fifths tuning is also called '''fifths''',  '''perfect fifths''', or '''mandoguitar'''.<ref>{{harvtxt |Sethares |2001 |loc="The mandoguitar tuning" 62–63}}: {{cite book |chapter=Regular tunings |title=Alternate tuning guide |first=Bill |last=Sethares |author-link=William Sethares |year=2001 |pages=52–67 |url=http://sethares.engr.wisc.edu/alternatetunings/regulartunings.pdf |publisher=University of Wisconsin; Department of Electrical Engineering|location=Madison, Wisconsin |access-date=19 May 2012 |id=[http://sethares.engr.wisc.edu/alternatetunings/alltunings.pdf 2010 ''Alternate tuning guide'', including a revised chapter on regular tunings]}}</ref> The conventional "[[standard tuning]]" consists of [[perfect fourth]]s and a single major third between the ''g'' and ''b'' strings:
:E-A-d-g-b-e'
All-fifths tuning has the set of open strings
:C-G-d-a-e'-b' or G'-D-A-e-b-f{{music|sharp}}',
which have intervals of 3 octaves minus a half-step between the lowest and highest string. The conventional tuning has an interval of 2 octaves between lowest and highest string.

All-fifths tuning is a tuning in intervals of [[perfect fifth]]s like that of a [[mandolin]] or a [[violin]]. It has a wide range. It was used by jazz guitarist [[Carl Kress]] in the form
