Complete Guide to Guitar Tuning
What is Standard Guitar Tuning?
Standard guitar tuning, also known as EADGBE tuning, is the most common tuning for 6-string guitars. From the thickest (lowest) string to the thinnest (highest) string, the notes are:
- 6th String (Low E): 82.41 Hz - E2
- 5th String (A): 110.00 Hz - A2
- 4th String (D): 146.83 Hz - D3
- 3rd String (G): 196.00 Hz - G3
- 2nd String (B): 246.94 Hz - B3
- 1st String (High E): 329.63 Hz - E4
How Does a Chromatic Tuner Work?
A chromatic tuner can detect and display all 12 notes of the musical scale (C, C#, D, D#, E, F, F#, G, G#, A, A#, B). Unlike a basic guitar tuner that only recognizes the six standard guitar notes, a chromatic tuner gives you the flexibility to tune to any pitch. This makes it perfect for:
- Alternate guitar tunings (Drop D, DADGAD, Open G, etc.)
- Tuning other stringed instruments (bass, ukulele, banjo, mandolin)
- Checking intonation across the fretboard
- Experimental and non-standard tunings
Understanding Cents in Guitar Tuning
When tuning your guitar, you'll see measurements in "cents." A cent is a unit of musical pitch that represents 1/100th of a semitone. Here's what you need to know:
- ยฑ5 cents or less: Considered perfectly in tune for most playing situations
- ยฑ10 cents: Slightly out of tune; noticeable in solo playing or recording
- ยฑ20 cents or more: Significantly out of tune; will sound dissonant
Our tuner displays the exact cents deviation, showing you whether you're sharp (too high) or flat (too low), so you can adjust your tuning pegs precisely.
Tips for Accurate Guitar Tuning
- Quiet Environment: Tune in a quiet room to minimize background noise interference
- Pluck Clearly: Strike the string firmly and let it ring - don't mute it immediately
- Tune Up: Always tune up to the pitch (from flat to in-tune) for better stability
- Check Twice: After tuning all strings, go back and check each one again
- Stretch New Strings: New strings need stretching and will go out of tune quickly at first
- Temperature Matters: Extreme temperatures can affect tuning - let your guitar acclimate
Common Guitar Tuning Problems
String Won't Stay in Tune: This could be due to old strings, loose tuning pegs, or nut/bridge issues. Try replacing strings first and ensure tuning pegs are tight.
Tuner Not Detecting Notes: Make sure you've granted microphone permissions, the string is ringing clearly, and there's minimal background noise. Position your device close to the guitar.
Different Tuning Across Fretboard: If open strings are in tune but fretted notes aren't, your guitar's intonation needs adjustment at the bridge.
Alternate Guitar Tunings
While standard EADGBE tuning is most common, many guitarists use alternate tunings for different sounds. Our chromatic tuner supports all tunings, including:
- Drop D: DADGBE - Popular in rock and metal
- Open G: DGDGBD - Used in blues and slide guitar
- DADGAD: DADGAD - Celtic and fingerstyle favorite
- Half-Step Down: Eb Ab Db Gb Bb Eb - Common in rock music
- Drop C: CGCFAD - Heavy metal and hard rock
