To tune a guitar half step down, lower every string by one semitone from standard tuning E A D G B E, so the strings read Eb Ab Db Gb Bb Eb. Use a chromatic clip-on tuner set to a reference pitch of A440, and tune each string down until the tuner shows its new note.
Know the target notes first
Standard tuning runs E A D G B E from the low string to the high string. Half step down moves every string down one semitone, so the target notes are Eb Ab Db Gb Bb Eb in the same order. Write the six notes down or keep them in view while you tune, since each string has its own target and guessing leads to a string tuned to the wrong note.
Set the tuner to chromatic mode
Clip the tuner to the headstock and switch it to chromatic mode, which reads any note instead of only the notes of standard tuning. Set the reference pitch to A440 so the tuner measures against the standard pitch. The tuner shows the note it hears and whether the string sits sharp or flat, so tune until the display settles on the target note.
Lower the low E string to Eb
Pluck the low E string and watch the tuner display. Turn the tuning peg to lower the pitch until the display shows Eb, moving in small turns and plucking the string again after each turn. Stop as soon as the display holds on Eb, since turning past the note means tuning back up and starting the string again.
Work across the remaining strings
Move to the A string next and lower it to Ab, then the D string to Db, the G string to Gb, the B string to Bb, and the high E string to Eb. Tune one string at a time and pluck each string again after every small turn of its peg. Keep the order the same each time so no string gets skipped.
Check every string a second time
Lowering one string changes the tension across the neck, so a string tuned first can drift while the later strings are tuned. Go back through all six strings, pluck each one, and correct any string that no longer sits on its target note. Repeat the check until every string holds its note.

Frequently asked questions
What notes do you tune to for half step down?
Eb Ab Db Gb Bb Eb, from the low E string to the high E string. Each string sits one semitone below standard tuning E A D G B E.
Do I need a special tuner to tune half step down?
A chromatic tuner works, since it reads any note rather than only the notes of standard tuning. Clip it to the headstock, set it to chromatic mode, and tune each string to its new note.
Why does my guitar drift out of tune after tuning down?
Strings settle after a change in tension, so play for a short while and then check each string again. Retune any string that has moved until the tuner holds steady on the new note.
