Standard guitar tuning: read the note before turning the peg

This guide is for an ordinary six-string guitar already set up for standard tuning. It is not an instruction to convert a different instrument, change string gauges or raise an unfamiliar tuning. If the guitar is new to you, ask a teacher or technician to demonstrate one complete tuning pass first.

Standard tuning runs E, A, D, G, B, E from the thickest string to the thinnest. Guitar string numbers run the other way: the thinnest is string 1. Fender confirms this standard sequence. Source: Fender standard tuning.

“Open” means sounding the string without pressing a fret. Trace that string all the way to its tuning post before touching a peg. Do not assume adjacent pegs follow an obvious order on every headstock.

Select standard guitar tuning if your tuner offers instrument presets. A chromatic mode can display notes outside the six targets; a guitar preset may show a string number. Remove a capo for this exercise and check that an alternate-tuning or flat-tuning setting is not selected. Follow your own tuner's manual for its display and calibration controls.

Pluck one string moderately, let it ring and keep the other strings quiet. A noisy room or several ringing strings makes interpretation harder. If the display jumps about, improve the signal before adjusting the instrument. Yamaha describes using a tuning meter on each open string, while Fender emphasises a clear pluck and sustained sound.

There are two questions: “Which note is the tuner detecting?” and “Is that note below or above the target?” Flat means below the intended pitch; sharp means above it. Many tuners place flat on the left and sharp on the right, but confirm the symbols on your device rather than relying only on a colour.

A centred A reading does not mean your D string is ready. It means the tuner is detecting an A accurately. Likewise, the two E strings share a letter but sound in different registers. A letter-only display is not permission to keep tightening until that letter appears again much higher.

For a string already close to its correct target, use a very small peg movement and pluck again. Check whether the pitch moved as intended. Peg direction depends on the headstock and winding; a universal “clockwise means higher” rule is unreliable. Do not make several blind turns while watching the previous fading note.

Use these invented readings to rehearse the decision before working on the guitar. Assume the string has been positively identified and was previously close to standard tuning.

1. The fifth string shows A, slightly flat. What needs to change?
2. The second string shows B, slightly sharp. What needs to change?
3. The fourth string shows a centred A. Is it finished?

Answers: first, the A needs a small rise in pitch. Second, the B needs a small fall. Third, no: the fourth string's target is D. Recheck which string is sounding, which peg belongs to it and the tuner mode. If the pitch is far from expectation, get help instead of guessing a large adjustment.

Now write a six-row tuning log: string, target, first reading, final reading. “G / a little sharp / centred G” is more informative than “green light.” The log is a temporary learning aid; you do not need to record every routine tuning forever.

After checking all six strings, make another gentle pass. Play a familiar chord, then check an individual string if something still sounds wrong. Do not try to repair persistent buzzing or poor fretted intonation by forcing the open strings away from their targets.

Stop if a peg resists unexpectedly, a string feels unusually tight, you hear a sudden crack, or you see a lifting bridge or damaged string. Ask a qualified repairer to assess structural concerns; this exercise does not include string replacement or instrument repair. Keep your face away from the strings while adjusting.

Once tuning is clear, try our two-chord transition exercise. For care between sessions, use the acoustic storage and cleaning checklist.
