Tuning is the first skill of every practice session and the most skipped lesson in guitar. Beginners are handed a tuner and a shrug, then spend weeks wondering why their perfectly formed chords still sound wrong. The answer is almost always that the guitar was out of tune, and nobody showed them how to fix it properly.
So here is the complete version: what standard tuning actually is, the clip-on method done right including the one rule that makes tuning stick, the by-ear method every player should own as a backup, and honest answers to how often and why it keeps drifting.
Standard Tuning: The Six Notes
From the thickest string to the thinnest, the six strings are tuned to E, A, D, G, B, E. The low E sits at the top as you look down at the guitar, and the high E is nearest the floor.
Generations of players have memorised the order with a phrase – take your pick of the classics or invent your own – but you will only need the crutch for about a week. Once these six strings are at pitch, every chord shape and every tab on this site means exactly what it is supposed to mean. Tuning is not preparation for playing. It is the part of playing that makes everything else true.
The Clip-On Method, Done Right
A clip-on tuner attaches to the headstock and reads the string’s vibration through the wood. It is the easiest and most reliable way to tune, and it is worth owning one.
- Clip it to the headstock and pluck ONE string on its own – start with the low E. Let it ring at medium strength.
- Read the note NAME first, then the needle. The display shows the nearest note plus how sharp or flat you are. The classic beginner disaster is tuning the needle to the centre while the note name reads D or F – a perfectly in-tune wrong note. Confirm the letter matches your target, then centre the needle.
- Always tune UP to pitch. If a string reads sharp, do not simply lower it to pitch. Drop it slightly below your target, then bring it up. This is the single most important habit in tuning, and it has its own section below.
- Use small turns, and learn which way raises the pitch on your guitar. Tuning pegs move the pitch faster than beginners expect, so think small. One minute spent learning which direction is ‘up’ turns tuning from a wrestling match into a ten-second job.
- Work through all six – E, A, D, G, B, E – then re-check the first string or two. Tensioning six strings subtly shifts the neck, and the quick second pass catches it. Total time once practised: under two minutes.
The Tune-Up Rule (Why It Matters)
This deserves its own moment because it is the difference between tuning that lasts a whole session and tuning that lasts a single song.
When you tune a string UP to its correct pitch, the string and its winding settle under stable tension that holds. When you tune DOWN to pitch, you leave a tiny amount of slack in the string and the tuning peg, and that slack works itself loose within minutes. So whenever a string reads sharp, deliberately drop it below the note, then come back up to it. Every professional does this without thinking, and it is the fix for the mysterious guitar that ‘won’t stay in tune.’
The By-Ear Backup: The 5th-Fret Method
Every player should own a tuner-free method, both as a backup for a dead battery and as genuine ear training. The system relies on one fact: each string, fretted at the 5th fret, sounds the same note as the next string played open – with one famous exception.
- Get one string to a reference pitch – the low E from any tuned instrument, a recording, or an app.
- Fret the low E at the 5th fret. It should match the open A string. Adjust the A until the two melt into one sound.
- Fret the A at the 5th fret to tune the open D, then the D at the 5th fret to tune the open G.
- Here is the exception: fret the G at the 4th fret, not the 5th, to tune the open B.
- Finish with the B at the 5th fret to tune the open high E.
When two notes are close but not identical, you will hear a wobble between them called beating. Adjust the string until the beating slows and disappears. It is slower than a clip-on and better for you, because every by-ear session is pitch-matching practice, and the players with great ears mostly built them right here.
| Tuning in one line: E A D G B E, thick to thin. Check the note NAME before the needle. Always tune UP to pitch from below. Small turns. All six, then re-check the first. Two minutes, every session, non-negotiable. |
How Often, and Why It Keeps Drifting
The honest schedule: every single session, at the very start, plus a quick re-check after heavy strumming, big bends, or a change in room temperature.
As for why it will not stay put: strings are elastic metal under high tension, and they respond constantly to playing, humidity, and temperature. Two situations are worth knowing about specifically:
- Brand-new strings drift for a day or two. They are still stretching. Speed it up by gently pulling each new string away from the fretboard and re-tuning a few times, until it holds.
- A guitar that won’t hold tune even after settling is asking for the shop. Slipping tuners and a poor setup are both fixable, and chronic detuning is never something you should have to live with.
Tune relentlessly and something sneaky happens within a few months: you start hearing that a string is slightly off before the tuner confirms it. That is your ear arriving – and the tuner was training it the whole time.
The Takeaway
How to tune a guitar: six notes, E A D G B E, using a clip-on properly – note name first, tune up from below, small turns, second pass. Add the 5th-fret method as your ear-building backup, with its famous G-string exception, and tune at the start of every single session.
Two minutes at the start of every practice is the cheapest sound upgrade in existence, because everything you play afterward is simply true. Tune first, always. Then go be in tune, loudly.
