How to tune a guitar? A simple step-by-step guide

How to tune a guitar? What you need to know first

Tune a guitar in standard tuning to E – A – D – G – B – E, from the thickest to the thinnest string. The easiest method is to use a clip-on or chromatic tuner; without a tuner, you can tune by ear by comparing neighbouring strings.

If you are wondering how to tune a guitar, start with the basics. Advanced players know them well, but they can save beginners a lot of uncertainty.

A guitar has six strings. In standard tuning they are E, A, D, G, B and E, from the thickest to the thinnest string. In Slovak and Czech notation, English B is often called H.

The values in the table apply to standard tuning with A4 = 440 Hz. Alternate tunings or down-tuning use different pitches and frequencies.

You will tune your guitar regularly. With frequent playing, that can mean every day; with new guitar strings, you may need to tune during playing until the strings settle.

How to tune a guitar with a tuner?

Many musicians start with an electronic tuner. It is accurate, easy to use and helps beginners understand what a properly tuned guitar should sound like.

Switch the tuner on and place it as close to the guitar as possible. Pluck one string, watch the note on the display and tighten or loosen the tuning peg until the needle is centred or the device turns green.

Move through the strings from the thickest to the thinnest or the other way round. Check them again at the end, because changing one string can slightly affect the tension of the others.

How to choose a good guitar tuner?

You can choose from standard, desktop, clip-on tuners and pedal tuners. Look at accuracy, display readability, chromatic mode, calibration and whether the tuner reads sound or vibrations.

Klasická ladička

A standard tuner is universal and suitable for most guitars. It usually has a microphone and often a cable input, which is especially useful for tuning an electric guitar.

Desktop tuners

Desktop tuners are larger, easy to read and stable on a table. They work well at home, in a lesson room or in a studio.

Klipová ladička

A clip-on tuner attaches to the headstock and reads vibrations. It is small, portable and practical for travel, rehearsal and home playing.

Pedálové ladičky

Pedal tuners are mainly designed for electric guitars and bass guitars. Stage players value them because they are accurate, durable and sit directly in the signal chain.

Also consider material, display size, visibility in the dark, features, price and brand. If you play an acoustic guitar or classical guitar at home, a simple chromatic or clip-on tuner is usually enough.

How to tune a guitar with a mobile app?

A mobile or online tuner works like a simple electronic tuner: it uses the microphone in your phone or computer. It is useful in a quiet room when you need a quick check and do not have a separate tuner with you.

In a noisy rehearsal room or on stage, a clip-on or pedal tuner is more reliable. With guitars that have an output, direct cable connection is a major advantage because room noise does not affect the microphone.

How to tune a guitar without a tuner?

Without a tuner, you tune by ear. First you need at least one reference note, ideally the low E string or a note from another instrument. Then compare neighbouring strings and adjust the differences.

Start with the thickest string and move across the guitar. Most neighbouring strings are five semitones apart, except the G and B strings, which are four semitones apart.

This method is useful for ear training, but beginners should still check with a tuner. A small mistake on the first string carries across the whole instrument.

Frequently asked questions about guitar tuning

How often should you tune a guitar?

Check tuning before every practice session or performance. New strings can go out of tune more often until they settle.

What are the guitar strings called?

In standard tuning, from thickest to thinnest, the strings are E, A, D, G, B and E.

How do you tune a guitar without a tuner?

Use one reference note, then compare neighbouring strings by ear. It is good practice, but check accuracy with a tuner.

Can you tune a guitar online or with a phone?

Yes. Online and mobile tuners are practical in a quiet room. In noisy places, a clip-on or pedal tuner is more reliable.

Why does the tuner show B instead of H?

Because many tuners use English note names, where the Slovak/Czech H is called B. In standard tuning, the second string may therefore appear as B.

Choose the best option

There is more than one correct way to tune a guitar. A tuner is the fastest and most accurate option, an app helps in a quiet room and tuning by ear develops your musical hearing. Choose the method that fits the situation and always check that all strings hold their pitch before playing.
