About Standard tuning
Mandolin tuning is G D A E in perfect fifths — the same as a violin — with each course doubled in unison. The paired strings give the mandolin its ringing, chorused sustain, from bluegrass chops to Celtic reels.
Tune one string of each pair at a time, muting its twin with a spare finger, then match the second string until the pair rings without beating. Unisons expose tiny errors, so take a second pass — beats you can hear are cents you can fix.
