About Standard Mandolin Tuning (GDAE)
Standard mandolin tuning is G-D-A-E from lowest to highest course. With exact octaves, this mandolin tuner targets G3, D4, A4, and E5, the same pitch layout used by violin tuning.
Use this mandolin tuner online as a GDAE note check: 4th course G3, 3rd course D4, 2nd course A4, and 1st course E5.
Most mandolins use four doubled courses, so each note has two strings tuned to the same pitch. Tune one string in the pair first, then match the second string to the tuner and listen for a clean unison without beating.
G-D-A-E mandolin tuning is used for bluegrass, folk, classical, Celtic, old-time, and singer-songwriter parts. The fifths-based layout gives the instrument its bright, compact range and makes scale shapes repeat cleanly across the neck.

Recommended Strings for Standard Mandolin Tuning
Use a dedicated mandolin string set for G-D-A-E tuning. A common light set runs roughly .010, .014, .024w, and .034w in paired courses, while medium sets feel tighter and louder. Because mandolins use doubled strings, replace and tune each matched pair together.
Common Chords in Standard Mandolin Tuning
G Major
A core bluegrass and folk shape that uses the low G course as a strong root.
D Major
Common in G and D tunes; the open D and A courses help the chord ring clearly.
A Major
Useful for fiddle tunes, singer-songwriter songs, and key-of-D progressions.
Chop Chords
Closed-position G, C, D, A, and E shapes use the fifths tuning for short, percussive rhythm playing.
How to Tune a Mandolin (G3-D4-A4-E5)
Select the Mandolin Standard preset so the tuner is locked to G3-D4-A4-E5.
Tune the 4th course to G3. Pluck one string in the pair first, then tune the second string until both G strings sound like one clear note.
Tune the 3rd course to D4, a perfect fifth above the low G course.
Tune the 2nd course to A4. This is concert A and can act as your reference point if you tune by ear later.
Tune the 1st course to E5. Make small adjustments because the high E strings are short and sensitive.
Strum all courses slowly, then recheck G3-D4-A4-E5. New mandolin strings often stretch, and paired courses can drift apart during the first few minutes.
