How to Tune a Guitar by Ear: A Family Guide to Getting in Tune

Learn how to tune your guitar by ear with simple techniques that work for beginners and experienced players alike.

1. Start with a reference note. You'll need one correctly tuned string to start. If you have a piano, keyboard, or pitch pipe, use it to tune your low E string (the thickest string). You can also use online tone generators or apps that play specific notes. If you don't have any reference, tune one string to what sounds reasonable to you - it won't be perfect pitch, but you can still practice the technique and play songs that sound good relative to that starting point.
2. Learn the guitar string names and order. From thickest to thinnest, the strings are: E (6th string), A (5th string), D (4th string), G (3rd string), B (2nd string), E (1st string). Many people remember this with the phrase 'Eddie Ate Dynamite, Good Bye Eddie.' The 6th string (low E) and 1st string (high E) are the same note, just two octaves apart.
3. Use the 5th fret method. This is the most common way to tune by ear. Press down the 5th fret of the 6th string (low E) - this creates an A note that should match your open 5th string (A). Pluck both strings and listen carefully. If the open A string sounds higher (sharper), loosen it by turning its tuning peg. If it sounds lower (flatter), tighten it. When they match perfectly, you'll hear the wobbling or beating sound disappear. Repeat this process: 5th fret of A string matches open D string, 5th fret of D string matches open G string. For the B string, use the 4th fret of the G string (this is the only exception). Finally, match the 5th fret of B string to the open high E string.
4. Listen for the 'beating' sound. When two notes are close but not exactly the same pitch, you'll hear a wobbling or pulsing sound called 'beating.' The closer the notes get to matching, the slower this beating becomes. When the strings are perfectly in tune, the beating disappears completely and you hear one clear, steady tone. This is your signal that the strings match.
5. Fine-tune with octaves and chords. Once all strings are tuned using the 5th fret method, check your work by playing some chords like G major, C major, or D major. If something sounds off, one or more strings likely need small adjustments. You can also check octaves: the 12th fret of any string should sound exactly like the open string, just higher. If it doesn't match perfectly, the string needs slight adjustment.
6. Practice regularly and be patient. Tuning by ear takes time to develop. Your ears need training to distinguish small pitch differences. Start by practicing when your guitar is only slightly out of tune, then work up to bigger adjustments. Don't get discouraged if it takes several attempts - even experienced musicians sometimes need multiple tries to get everything perfect.
