Strings & Tuning
Fit a new set, get it in tune, and pick the right gauge next time.
One string at a time
Change strings roughly every three months of regular playing, or sooner if they sound dull or look corroded. Working one string at a time keeps the neck under even tension.
{{ ss.n }}
{{ ss.text }}
A string winder with a built-in cutter and bridge-pin puller turns this into a three-minute job. It is the cheapest tool worth owning.

Tuning the guitar to itself
No tuner and nothing to tune to? The guitar can tune itself. It will not be at concert pitch, but it will be in tune with itself, which is all you need to play alone.

String gauges
Lighter gauges are easier to bend and fret; heavier gauges give more volume and sustain.
{{ gr.type }}
{{ gr.gaugeVal }}
{{ gr.note }}
Changing gauge changes the tension on the neck, so a big jump either way usually needs the truss rod and intonation resetting. Moving one step is normally fine; moving two or more is worth a setup.
Strumming & Rhythm
Patterns to play, and a metronome to keep you honest.

Beginners: start slowly. Once the pattern feels comfortable and you are not thinking about it, nudge the metronome up a few beats at a time.

Fingerpicking
Playing bass, chords and melody at the same time — with your hand rather than a pick.
Setting the hand up
Fingerpicking is less about speed than about the hand staying still. Get the position right and the patterns come quickly.

The finger names
Fingerstyle music labels the picking hand with four letters, from the Spanish. You will see them written above the notes.

Patterns to work through
In order of difficulty. Learn each one until your hand does it without you watching, then move on. Slowly and evenly beats fast and ragged, every time.

Mirrored for a left-handed guitar. Every part sits in the same place — just on the other side.
Bass guitars share the same parts, usually with four thicker strings and a longer neck.
Chords, Notes & Scales
The shapes, the fretboard behind them, and the scales they come from.
Reading a chord diagram
Left-handed mode is on, so these diagrams are mirrored: the thickest string is on the right.
The six vertical lines are the strings as you look down at the guitar in playing position. The thick line across the top is the nut, and the horizontal lines below it are the frets.
A dot means press that string at that fret. An o above a string means play it open, and an × means do not play it at all.
The line under each diagram tells you where the shape sits — open position, or which fret a barre shape starts on.
Using a capo
A capo clamps across the neck and shortens every string at once, so a shape you already know comes out in a higher key. Play a G shape with the capo on the 2nd fret and you are playing an A.

Barre chords
One finger pressing several strings at once. It feels impossible for a fortnight and then it does not — almost always technique rather than strength.

Buying & Selling
How to judge a guitar before you hand over money — and how to get a fair price when it is time to move one on.
Your first guitar
Buy the cheapest guitar that plays well, not the cheapest guitar. A badly set up instrument fights you on every note and is the most common reason people give up in the first month.

Walk away from a twisted neck, a lifting bridge, or a truss rod that will not turn. Everything else — frets, nut, electronics, a bad setup — is fixable, and worth haggling over rather than avoiding.

Types of guitars
Nine shapes cover most of what you'll run into.
Acoustic — Dreadnought
Large-bodied steel-string with a big, punchy low end. The most common acoustic shape.
Acoustic — Concert / Parlor
Smaller-bodied, comfortable seated, with a more focused midrange.
Classical (nylon-string)
Wide neck and nylon strings, played fingerstyle — the foundation of classical and flamenco.
Electric — Solid body
Bright, versatile tone from magnetic pickups. Stratocaster and Telecaster-style shapes are the archetype.
Electric — Single-cut
Warmer, thicker tone, often with humbucker pickups. Les Paul-style shape.
Bass Guitar
Thicker strings tuned an octave below a guitar, carrying the low end of a band.
12-string guitar
Six courses of paired strings for a fuller, chorused sound, common in folk and jangle-pop.
Archtop / Hollow-body
A hollow, arched body with a warm, woody tone — the classic choice for jazz.
Resonator
A metal cone inside the body amplifies the sound acoustically, giving a bright, metallic tone favored in blues and bluegrass.

Setup & Care
A guitar is wood, wire, and glue — small habits keep it sounding right for decades.

Storage & humidity
{{ it.text }}
Buy a hygrometer
A hygrometer measures the humidity of the air. A small digital one costs about the price of a set of strings, and it is the cheapest insurance a wooden guitar can have — it tells you about a problem weeks before the guitar does.
{{ hp.title }}
{{ hp.text }}
Solid-wood acoustics are the ones that really care. Laminate bodies and solid-body electrics are far more tolerant, though necks and fretboards move on any guitar.
What a setup does
A setup is a handful of small adjustments that decide how a guitar feels under your hands. Most instruments leave the factory adjusted for shipping, not for playing, and a good setup is the single biggest improvement you can make to a cheap guitar.
{{ sp.title }}
{{ sp.who }}
{{ sp.text }}
Intonation
Intonation is whether the guitar stays in tune with itself as you move up the neck. Open chords sound fine, then something up at the 7th or 9th fret rings sour — that is intonation, not your tuning.
Checking it
{{ istep.n }}
{{ istep.text }}
On an electric each saddle moves individually, so intonation is adjustable at home with a screwdriver and a tuner. On an acoustic the saddle is a single piece and correcting it means shaping or replacing it — that one is a job for a tech.
When to see a tech
Plenty of maintenance is yours to do. These are the jobs worth paying someone for — a full setup costs less than you would think, and it transforms a guitar.

Amps
The amp shapes your tone as much as the guitar does.

Starting points by style
Rough dial positions to start from — every amp responds differently, so treat these as a jumping-off point and tweak to taste.
GAIN
BASS
MID
TREBLE
Clean / Country
Low gain, bright EQ with treble up slightly, a touch of spring reverb, and a compressor if you want punchy, even picking.
GAIN
BASS
MID
TREBLE
Blues
Push the amp into light, natural overdrive rather than a pedal, mid-forward EQ, and a moderate amount of reverb.
GAIN
BASS

TREBLE
Rock / Lead
Medium-high gain with a mid boost so solos cut through the mix, plus a delay for sustain on longer notes.

Metal
High gain, tight low end (roll bass back slightly to avoid mud), a noise gate, and mids scooped or boosted depending on the sub-genre.

Acoustic-electric
Keep EQ close to flat for a natural tone, add only light chorus or reverb, and go easy on compression.

Jazz
Very low gain or fully clean, warm and rolled-off treble, and a hollow-body guitar into a flat-response amp for a round, mellow tone.

Classical
Nylon-string guitars rarely need an amp, but if amplified via a pickup, keep it flat and clean with just a touch of reverb to preserve the natural tone.

Bluegrass
Bright, clean, and dynamic with minimal effects, so fast flatpicking and interplay with other acoustic instruments stay crisp and articulate.

Feedback, and how to stop it
That rising squeal or low howl is the amp's own sound getting back into your pickups and going round again. It is a loop, so you break it by changing one part of the loop.

What makes a good lead
Your cable is part of your signal chain, not an accessory. A bad one hisses, crackles and quietly takes the top end off your tone.

Accessories

Plectrums
A pick is the cheapest thing that will change your sound. Buy a mixed pack, keep the ones you reach for, and lose the rest down the back of the sofa like everybody else.
