The harmonic produced at fret 7 has a frequency that is three times higher (330 Hz) and we hear that as E - a perfect 5th plus an octave higher than the open 5th string. It has the same pitch as the fretted note at fret 12. The harmonic produced at fret 12 on that string has a frequency of twice that, or 220 Hz, so we hear it as the A one octave higher in pitch. An altered guitar tuning such as DADGAD will have its unique set of harmonics occurring above exactly the same frets as in standard (or any) tuning.įor example, string 5 in standard tuning is A and has a frequency of 110 Hz (110 vibrations per second). That means every open string has its own set of harmonics, but they all share the same fret locations regardless of string and also regardless of tuning. Those that are useful to guitarists (easy to produce and tuneful) are those that occur at:Įach division produces an audible harmonic which is a multiple of the fundamental frequency (vibration rate) of the open string. Natural harmonics occur at exact divisions (nodes) of the length of the vibrating string. Guitar Frets and Harmonics Pitches in Standard Tuningįret 12 - E A D G B E - one octave higher than the open stringsįret 7 - B E A D F# B - one octave higher than the fretted notesįret 5 - E A D G B E - two octaves higher than the open stringsįret 4 - G# C# F# B D# G# - two octaves higher than the fretted notesįret 9 - G# C# F# B D# G# - Same pitches as fret 4 Bass strings at the 12th & 7th frets are the easiest to work with and practise on. Don't be too quick either or all you'll hear is the open string ringing out. Don't be too slow in removing your finger or it will mute the harmonic and prevent it from ringing out clearly. Your finger must be touching the string exactly above the fret metal. Don't place your finger just behind the fret like you do when fretting a note. Then pluck the string (with any picking-hand finger) and immediately release your fretting-hand finger from the string and the harmonic will ring out with its distinctive tone. Don't press down - just touch it lightly. If you're unfamiliar with playing natural harmonics on the guitar, they're produced by lightly touching any guitar string with your fretting-hand finger tip over the specified fret.
