Online Mandolin Tuner

Bluegrass music uses standard tuning for the most part. From the lowest string set to the highest string set the tuning is GDAE. This tuning is the same as a violin or fiddle, but instead of 4 strings it has 4 pairs of strings (2 G strings, 2 D strings, 2 A strings and 2 E strings). While tuning your mandolin stroke one string of a pair and mute the other string using the pick.
Sometimes a Crosstuning is used in tunes like "Get Up John". Monroe used F#A DD AA AD for that tune. Some other tunings are used for certain tunes and in old time songs. The pairs of strings may be tuned to GDGD.

How it works?
1. Select your instrument and press 'Start Tuning' button.
2. When prompted, allow your browser to use the microphone.
3. Pluck the string you want to tune and the tuner will highlight the note letter for you and show you if you are sharp or flat.
4. When the note turns orange, it means it is close to being in tune.
5. When the note turns green, that string is in tune.
