What is standard mandolin tuning?

Typical standard mandolin tuning is GDAE. This is widely used in bluegrass music and is the same tuning as violin or fiddle. The mandolin does however has 4 pairs of strings, i.e. two G strings, two D strings, two A strings and two E strings, which are tuned to exactly the same note. These pairs of strings create a cool chorus-like effect, very similar to the sound of the 12 string guitar.

The open strings can be located as follows, from left to right looking at your mandolin with the headstock at the top:

  • G: the 4th string (the furthest left on the fretboard)
  • D: the 3rd string
  • A: the 2nd string
  • E: the 1st string

How to use MandoTabs mandolin tuner?

This tuner supports the most popular mandolin tunings. Standard tuning is GDEA, which is the most common mandolin tuning. Feel free to experiment though, some more exotic tunings are also available: Gee-DAD (GDAD), open G (GDGB), sawmill (GDGD) and high-bass (ADAE). The standard, Gee-DAD and Open-G mandolin tunings are the most popular tunings in bluegrass / old-time music.

Once you have selected a tuning, simply tap on the tuning pegs to ring out the root note for each string. Listen carefully and tune your mandolin to that note by ear. Some people find a monotone beep easier to tune to. Select 'beep' if you want to use that sound instead of the natural mandolin strings. While tuning your mandolin stroke one string of a pair and mute the other string using the pick.
