Cross tuning GDAD Tuning on Mandolin

Cross tuning GDAD tuning is G3 D4 A4 D5, written GDAD. Lower the 1st course a whole step, from E5 to D5. The other three courses stay at standard pitch.

Tune by ear, no microphone needed

Play a reference pitch and match your instrument to it. This uses the same oscillator as the tone generator and needs no permission at all.

Why guitarists use Cross tuning GDAD tuning

With D sounding on both the 3rd and the 1st course, the instrument gets a built-in drone an octave apart, the same trick old-time fiddlers use with cross tuning. Modal tunes in D sit naturally under the fingers as a result.

Where you will hear it: old-time, Irish traditional, modal tunes in D. That list is deliberately limited to genres and playing traditions. Attributing a tuning to specific songs or players is the kind of claim that needs a source, and this page does not make claims it cannot back up.

Cross tuning GDAD compared with standard GDAE tuning

This is the table that tells you how far to turn each peg, in semitones and in hertz. A negative semitone value means the string goes down.

1st courseE5659.26D5587.33-2 semitones (-71.93 Hz)

Notice that equal semitone steps are not equal hertz steps: the same whole step is worth about 9 Hz down at the bottom string and far more at the top. That is why tuners report cents, which are proportional, rather than hertz.

How to tune to Cross tuning GDAD, string by string

  1. Play the 4th course open and adjust until the tuner reads G3 at 196.00 Hz. Aim to land inside five cents.
  2. Play the 3rd course open and adjust until the tuner reads D4 at 293.66 Hz. Aim to land inside five cents.
  3. Play the 2nd course open and adjust until the tuner reads A4 at 440.00 Hz. Aim to land inside five cents.
  4. Play the 1st course open and adjust until the tuner reads D5 at 587.33 Hz. Aim to land inside five cents.

Retune in two passes. Changing the tension on one string changes the pull on the neck, so the strings you set first will have drifted slightly by the time you finish the last one. That effect is larger the further the tuning sits from standard, so a tuning that moves four or more strings almost always needs a third pass.
