Half-Step Down Tuner Online
Tune your guitar by ear with your microphone, free.
Half-step down keeps every standard chord shape but drops the whole guitar a semitone, for a thicker tone, slinkier string feel, and an easier match to gravelly vocals. Tune down below in seconds.
About Half-Step Down Tuning
Half-step down tuning is Eb Ab Db Gb Bb Eb (low to high) — standard EADGBE with every string lowered by exactly one semitone. The relationships between the strings never change, so all of your chord shapes, scale patterns and licks stay identical; the entire instrument simply sounds one fret lower. Players reach for it for a darker, heavier tone, slightly looser strings that are easier to bend, and to drop the key for singers.
To reach it from standard tuning, lower every string by one half step: E→Eb, A→Ab, D→Db, G→Gb, B→Bb, and high E→Eb. Work string by string, tuning each down a single semitone until the dial reads the flat target. Because all six move the same amount, there is no need to learn new fingerings — a barre chord at the third fret now sounds a half step lower than usual.
This tuning is a studio and stage favourite from Hendrix to modern metal, valued for its slinky feel and warmer, fatter sound.
