Guitar

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.

Note-by-Note Tendencies

🔧 Equipment & Setup

💡 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

Ensemble Intonation

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 fanned frets or microtonal frets; commercial 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): rely on perfect 5ths between open strings; pitch checks 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
