Nothing sounds good on an out-of-tune guitar — not chords, not songs, not you. And nothing kills a beginner's confidence faster than practicing for a week and thinking the bad sound is their fingers, when it was the tuning all along.
So before anything else: this is the one skill you'll use literally every time you pick up the instrument. It takes two minutes once you know the routine.
What "in tune" means
string: 6 5 4 3 2 1 name: E A D G B e sound: low ------------------→ high
Standard tuning, thickest string to thinnest. Two E's, two octaves apart — that's why the thin one is written as a small e.
The easy way: use a tuner
Use the free tuner right here on xpex — it listens through your microphone, shows you the note it hears, and a needle tells you whether you're flat (too low) or sharp (too high).
The routine, for each string from thick to thin:
1. Pluck the open string once, medium strength, and let it ring.
2. Look at the note name first. If you're tuning the A string and the tuner says G, you're a whole step low — wind up slowly until it says A. Wrong note first, needle second.
3. When the note name is right, make small turns until the needle centers and locks.
4. Always tune UP to the note. If you overshoot, drop below and come back up — strings hold tune better when the last move was tightening.
The ear method (worth learning early)
Tuners are great, but your ear is the instrument behind the instrument. The classic 5th-fret method tunes each string to the one above it, and it quietly trains your ear every time you use it.
The 5th-fret method
E string, 5th fret → open A A string, 5th fret → open D D string, 5th fret → open G G string, 4th fret → open B ← the exception B string, 5th fret → open e
Fret the 5th fret of each string and it should sound identical to the next open string — except the G string, where it's the 4th fret. That one exception trips everyone once.
Why your guitar keeps going out of tune
New strings stretch. Wood moves with temperature and humidity. Beginner-guitar tuning pegs are often loose. All normal.
Two habits fix most of it: tune every single time you sit down (two minutes, not optional), and if the guitar or strings are new, gently pull each string away from the fretboard a few times, retune, and repeat — that pre-stretches them so they settle in days instead of weeks.
If a string slips constantly even after stretching, the tuning peg may need a quarter-turn of tightening at its screw — or it's a sign the guitar needs a proper setup, which is normal and cheap.
Make it automatic
Tuning is lesson one in our free Foundations path for a reason: the players who keep going are the ones whose guitar sounds good in week one. Tune first, then play — every time, forever.
