Guitar

The guitar uses frets for pitch placement, but intonation still varies with technique, string age, setup, and playing position. Bending, vibrato, and barré chord pressure all affect pitch.

Common Pitch Tendencies

  • Fretted notes can go sharp from pressing too hard
  • Higher frets tend sharper due to intonation compensation limits
  • Barré chords often sharp from excessive pressure
  • Old or worn strings lose intonation accuracy
  • Capo placement affects intonation across all frets
  • Bending technique requires precise pitch targeting
  • Open strings vs fretted: slight discrepancy is normal (equal temperament)
  • Classical guitar nails/flesh affect attack and perceived pitch

Temperature & Warm-up

Temperature and humidity significantly affect guitar tuning. Wood expands/contracts, strings change tension. Allow 5–10 min to acclimate before assessing intonation.

Register Guide

Low Register

Open position (frets 0–4): Most stable intonation area. Use light pressure. Compare open strings and fretted notes to check setup. If 1st-fret notes are sharp, nut may be too high.

Middle Register

Mid position (frets 5–9): Intonation depends heavily on saddle compensation. Check octave at 12th fret harmonic vs fretted note — if fretted is sharp, saddle needs to move back.

High Register

Upper position (frets 10–16): Most prone to sharpness from setup issues. Very light touch essential. If consistently sharp, the guitar likely needs a professional setup.

Harmonics

Harmonics (12th, 7th, 5th fret): Pure overtones that don't depend on fretting — excellent pitch references. Use 12th fret harmonic to check octave intonation.

Equipment & Setup

🎻 Strings

  • Fresh strings intonate more accurately — change every 2–4 weeks for serious practice
  • Coated strings (Elixir, etc.) maintain intonation longer but may have different feel
  • String gauge affects intonation: heavier strings need more saddle compensation
  • Nylon strings (classical): stretch significantly when new — retune frequently for first 48 hours
  • Steel strings: less stretch but more affected by temperature changes
  • Wound vs plain G string: affects 3rd string intonation differently
  • Plain vs wound 3rd string determines your problem string: on electrics with a plain (unwound) G, the G is the thickest plain string and the hardest to intonate — it needs the most saddle compensation and is a frequent cause of sour open-position chords. Acoustic sets use a wound G, which shifts that role to the plain B string.

Instrument

  • Action height: too high = pressing sharp; too low = buzzing and false pitch readings
  • Saddle compensation: each string needs different compensation for accurate intonation across frets
  • Nut slots: must be cut to correct depth — too high makes first position sharp
  • Neck relief (truss rod): slight forward bow is normal; excessive bow affects mid-fret intonation
  • Capo: spring capos can press too hard (sharpness) — screw-type allows pressure control
  • Fret wear: flat spots on frets cause buzzing and intonation problems — level or replace

Practice Tips

  • Use minimum finger pressure — just enough for a clean note
  • Check intonation: 12th-fret harmonic should match 12th-fret fretted note
  • Change strings regularly for accurate intonation
  • Get a professional setup at least once a year
  • Train bends with a tuner — full-tone bends sit ~10¢ flat for most players who don't check; visualize the target pitch before bending
  • Barré chord pressure: just enough that all strings ring — extra pressure sharpens the lowest frets by 5–10¢ across the chord
  • Tune before every practice session and re-check after 10 minutes — string tension settles as the wood warms; cold strings drift up to 5¢ in the first 10 minutes
  • Use harmonics as reference points when playing up the neck
  • Fretted-string vibrato can only raise pitch — bending the string across the fret adds tension, and there is no way to dip below the fretted note (unlike violin vibrato, which centers on the pitch). Wide vibrato therefore reads sharp on a tuner: keep vibrato narrow, and start every vibrated note from a dead-centered pitch.
  • Sweetened tuning: many players deliberately tune the 2nd (B) string 2–4¢ flat of equal temperament so the major 3rd in open G and E chords beats less — a small, practical just-intonation compromise. Check the result on your most-used chords, not just open strings.

Ensemble Intonation

Ji Deltas Instrument

  • major-third
  • perfect-fifth
  • minor-third

Section Role

  • Guitar is a FRETTED ET instrument — pure-interval adjustments require microtonal bending or capo offsets
  • In an ensemble, guitar TYPICALLY adopts the ET pitch center; other instruments adjust to the guitar
  • Acoustic guitar + violin / fiddle: violin will sit ~+2¢ above guitar on perfect 5ths — accept the conflict or have violin compromise
  • Drop tunings (D, C, Open G, DADGAD): change the resonant pitches; the open strings naturally re-tune

Genre Pitch Center

  • Pop / rock: A=440 standard
  • Acoustic folk: A=440; capo work makes pitch center context-dependent
  • Jazz: A=440
  • Classical guitar: A=440 reference; gut/nylon strings have more pitch drift than steel
  • Detuned styles (drop D, drop C): pitch reference is the lowest open string, not A

Barre & Open Chords

  • Open chords (E, A, D, G, C): use open strings and adjacent fret intonation; tone is fuller, intonation is more reliable
  • Barre chords: every string is fretted; intonation depends on consistent finger pressure + proper setup
  • Barre chord intonation: F (1st-fret bar) is the most-played barre and the trickiest; light pressure is essential
  • A common error: pressing too hard on barre chords sharpens every note 5–10¢; ensemble blend suffers
  • Open vs barre voicing of the same chord: choose based on context — open for ringing fullness, barre for moveable consistency

Setup & Saddle Compensation

  • Saddle compensation: each string's saddle position is set to compensate for string stiffness — varies by string gauge
  • Lighter gauge strings: less saddle compensation needed; lighter tension allows easier bends but is more pitch-sensitive
  • Heavier gauge: more saddle compensation; more pitch stability under aggressive playing
  • Truss rod relief: too much relief = high action = sharp fretted notes; too little = buzz + unstable pitch
  • Action height at the 12th fret: too high = sharper fretted notes (more bending occurs while fretting)
  • Intonation setup procedure: tune the open string, play the 12th-fret note, compare; adjust saddle position to match

Capo Compensation

  • Capo location effect: capos at the 1st-3rd fret have minimal pitch effect; high capos (5th+) compound saddle compensation errors
  • Spring capos: pressure varies — can over-compress strings and sharpen pitch by 5-10¢
  • Screw-type / partial capos: more pressure control; preferred for precise intonation work
  • Re-tuning after capo: ALWAYS recheck tuning at the capo position; the "in tune at the open" assumption fails for 5th-fret-and-above capos

Tuning Systems

  • Equal temperament (ET): the default; guitars are physically constructed for ET fret spacing
  • Just intonation: requires curved 'True Temperament'-style frets, staggered/movable frets, or per-string nut/saddle offsets; fanned (multi-scale) frets change scale length per string but are still equal-tempered. Commercial JI instruments are rare
  • Stretch tuning (octaves slightly wider than 2:1): used on some pianos but NOT applicable to guitar — fret spacing is fixed
  • Open tunings (Open G, Open D, DADGAD): mostly octaves, 4ths, and 5ths between open strings, plus one major 3rd in Open G (the B) and Open D (the F#) — that 3rd is the string many players sweeten a few cents flat; check the open strings first

Effects & Electronics

  • Pitch-shift pedals (whammy, harmonizer): can introduce micro-delay that affects ensemble timing
  • Tremolo (Floyd Rose, Bigsby): floating bridges drift pitch; lock the bridge or check tuning frequently
  • Active vs passive pickups: pitch is the SAME, but compression / EQ shape can make slight pitch errors more audible
  • Wah / envelope filters: shift HARMONIC emphasis, NOT fundamental pitch
