Half Step Down

Everything down one fret. Same shapes, a slacker feel, and a friendlier key for most voices.

Note names won’t tune your guitar.

Knowing the strings should read E♭ A♭ D♭ G♭ B♭ E♭ is the easy half. Landing each frequency — and knowing whether you are nine cents flat or three — is the half that needs an ear or an instrument.

1
Open Dial and play a string
It listens as soon as you play. Nothing to press.
2
Turn each peg until the needle centres
Every string drops a half step — one fret — from standard.
3
Check the remaining strings
Changing tension on one string shifts the neck slightly. The rest usually need a nudge.

What Half Step Down is for

Hendrix, Stevie Ray Vaughan, and a large share of the rock canon lived here. Strings bend more easily, the tone thickens slightly, and songs written around E-shaped chords land in E flat — often a better fit for a singer.
