Drop D Tuner Online
Tune your guitar by ear with your microphone, free.
Drop D is the most popular alternate tuning on guitar — lower your sixth string a whole step and you unlock a heavy, droning low end and one-finger power chords on the bottom three strings. Pluck a string and let our tuner guide you to pitch.
About Drop D Tuning
Drop D tuning is D A D G B E (low to high) — standard EADGBE with only one change: the thick low E string is dropped a whole step down to D. Every other string stays exactly where it is, which is why Drop D is the fastest alt tuning to reach and the easiest to undo mid-set.
To get there from standard tuning, leave the A, D, G, B and high-E strings alone and tune only the low E string down a whole tone to D. Match it an octave below your open D (fourth) string — when the two D strings ring in unison an octave apart, you are there. The lowered string gives you a deep, resonant root and lets you fret a full power chord across strings six, five and four with a single barred finger.
Because only one string moves, Drop D keeps all of your familiar chord shapes on the top five strings while adding a darker, chunkier low register that is perfect for riff-driven music.
