Outgrow the lessons.
One page, one goal: get you to where you don't need a teacher, because you see the neck. Five shapes tile the whole fretboard; learn to read them and you can play any song in any key, move a progression wherever your voice sits, and land solos in a live jam by knowing where the right notes are before you reach. Interactive maps, ears-first drills, and practice files your tab app opens: the map most players wish they'd had on day one.

Strings & Tuning
A standard guitar has 6 strings. From thickest (lowest pitch) to thinnest (highest pitch) they are tuned to:
Mnemonic to Remember
Eddie Ate Dynamite, Good Bye Eddie
💡 Tip
The 6th string (thickest) is closest to your face when holding the guitar. The 1st string (thinnest) is closest to the floor. Click the play buttons above to hear each string's pitch!
Tuning by ear is a skill; train it early. Tick the repeat box, play a reference note, and turn the peg until the two sounds melt together: when close, you'll hear a slow "wah-wah" beating that disappears exactly at in-tune. Guitars also tune to themselves: fret 5 on a string sounds the next open string (fret 4 on the G string). Check yourself with the Tuner afterwards.
Chords
A chord is three or more notes played together. Every root, three flavors, and the ringed ones are the beginner set: learn those first, everything else is one barre shape away.

Songs That Teach
Multi-genre and multi-key on purpose: every classically- or jazz-trained metal player got scary because they trained outside their genre, and living in one key builds habits you'll have to unlearn. Each pick below smuggles in a specific skill.
Every title and artist links into your Library with the search prefilled, so if you've got the tab, it's one click away.

Reading Tabs & Notation
Guitar tablature (tabs) is the most beginner-friendly way to read guitar music. Each line represents a string, and numbers tell you which fret to press.
How to Read a Tab
e|---0---1---3---| ← 1st string (thinnest, high E)
B|---1---0---0---| ← 2nd string
G|---0---0---0---| ← 3rd string
D|---2---2---0---| ← 4th string
A|---3---3---2---| ← 5th string
E|---x---x---3---| ← 6th string (thickest, low E)

Reading standard notation
Tab tells you where to put your fingers. Notation tells you when, and the "when" is what makes a riff sound like the record. Tab software shows both at once, so learn to peek at the top staff.
The staff: lines and spaces (treble clef)
Fun fact: guitar music is written an octave higher than it sounds; otherwise most of our notes would drown in ledger lines below the staff.
Note values: the rhythm alphabet
| Note | Looks like | Beats (in 4/4) | Count out loud |
|---|---|---|---|
| Whole | 4 | "1 – (hold through) 2, 3, 4" | |
| Half | 2 | "1 – 2, 3 – 4" | |
| Quarter | 1 | "1, 2, 3, 4", the foot-tap note | |
| Dotted quarter | 1½ | "1 – (2) &", usually paired with an eighth to fill the beat: the classic long-short dotted rhythm | |
| Eighth | ½ | "1 & 2 & 3 & 4 &" | |
| Sixteenth | ¼ | "1 e & a, 2 e & a", metal's favorite |
A dot beside any note adds half its value again (dotted half = 3 beats). A dot above or below the note head means staccato: play it shorter. A rest is the same duration of deliberate silence, and silence is played, not skipped.
Time signature & tempo
4/4. Top number: beats per measure. Bottom number: which note gets one beat (4 = quarter note). Nearly every rock and metal song lives here. 6/8 is the lilting six-count you'll feel in 6/8 ballads. Tempo (BPM) = beats per minute, so 60 is one beat per second, most rock sits 100–140, thrash lives north of 180.
Notes on the Fretboard
Music uses 12 unique notes that repeat in a pattern called an octave. Click on any note below to highlight it across the fretboard.
Quiz: find the note
Click the fret where the note lives. Ten questions, and it remembers your best score.
The Chromatic Scale
All of Western music is built from these 12 notes, repeating up and down in pitch:
Each fret on your guitar moves one half-step (semitone) up this sequence.
Keys, Families & Progressions
Songs live in a key, and every key owns a family of chords built from its scale. Learn the family once and thousands of songs become rearrangements of chords you already have. The family below is the key this page is currently in, so pick any key in the progression table (or any other tool) and it follows. The pentatonic board further down stays in A minor / C major as a worked example: the beginner-friendliest neighborhood on the instrument, and an example, not a home address.
The chord family
A minor pentatonic: A home vs C home
Loop an Am chord and land phrases on the orange notes; loop C and land on green. Same box, two centers of gravity. The big cluster at frets 5–8 is "the box" from every guitar video ever made, and it wraps the Em-shape Am barre chord at fret 5, which is why it's there.
Progressions worth wearing out
The numerals are the portable part: lowercase = minor, uppercase = major, ♭ = a degree borrowed from the minor scale, ° = diminished. Learn the numeral pattern once and it works in every key, so switch the key below and watch the shapes change while the numbers stay put. Pick a major key for the major-key progressions, a minor key for the minor ones.
| Numerals | Progression | Feel | You've heard it in |
|---|
Hit ▶ on any row and it loops: two bars a chord, so you can solo over it with the boxes from the CAGED section (same key, they're all in sync).
Ear Training: Find the Key of Anything
- Hum home base. Listen to the song and hum the note it keeps wanting to rest on. Melodies always pull back to the root, and that gravity is what you're hearing.
- Hunt it on the low E string. Slide up one fret at a time until your fretted note melts into the hum. That fret's name = the root. (Bass is the boss: when in doubt, listen for what the bass player lands on.)
- Major or minor? Play the minor pentatonic box at that root, then the major. One sounds "inside," one clashes. Trust your ear, not the chart.
- Play the scale in three places. Same notes, three neighborhoods, and now the whole neck belongs to you.
Interval trainer
Two notes play. Name the gap. This is the muscle that turns "I hear it" into "I know what it is".
What Chord Am I Holding?
Click the frets you're pressing (click again for a muted string, once more to clear). The name appears as soon as there's enough to go on, from power chords to the jazz shelf (maj7, m(maj7), dim7, 9ths, altered dominants…).
Capo & Transpose
Two questions this answers: "I'm playing these shapes with a capo, what key am I actually in?" and "I need this song in a different key, where do I put the capo?"
Scales
A scale is a set of notes arranged in a pattern of intervals. Scales are the foundation of melodies and solos.
A Minor Pentatonic
Intervals Explained
Pentatonic neighborhoods: one scale, three homes
Box 1 · Open position (home turf)
e|------------------------------0--3--| B|------------------------0--3--------| G|------------------0--2--------------| D|------------0--2--------------------| A|------0--2--------------------------| E|-0--3-------------------------------| roots: open E, 2nd fret D string
Box 2 · 12th fret (same shape as the A-minor box at 5, moved up)
e|-----------------------------------------12--15--| B|---------------------------------12--15----------| G|-------------------------12--14------------------| D|-----------------12--14--------------------------| A|---------12--14----------------------------------| E|-12--15------------------------------------------| root: 12th fret low E
Box 3 · 7th fret (the bridge between them)
e|----------------------------------7--10--| B|--------------------------8--10----------| G|---------------------7--9----------------| D|----------------7--9---------------------| A|--------7--10----------------------------| E|-7--10-----------------------------------| roots: 7th fret A string · 9th fret G string
Same five notes, halfway up the neck, and it connects the open box to the 12th-fret one, so a phrase can travel the whole neck without leaving the scale. (The CAGED section calls this region box 4.)
The movable trick
Box 2's shape is the movable pentatonic box. Root on the low E string = name of the scale. Slide it to fret 5 and it's A minor pentatonic. Fret 3 = G minor. Fret 7 = B minor. One shape, every key.
CAGED: Five Grips Tile the Whole Neck
There are only five open chord shapes: C, A, G, E, D. Every chord lives in five places up the neck, cycling through those shapes in that fixed order. The pentatonic patterns aren't arbitrary boxes; each one is drawn around one of these grips: the chord is the skeleton, the scale is the flesh. When a phrase lands on a chord tone it sounds resolved, and in this system you can literally see the chord tones, because they're the grip your hand already knows.
The five shapes and the notes inside them
Triad math: a major chord is just three notes (root, third, fifth) repeated across the strings. Every letter under each diagram is one of those three. Nothing else is allowed in; that's why they sound so solid.
Find the five positions in any key
This is the drill that makes CAGED stick: pick a key and read the neck left to right, because the shapes always tile in C-A-G-E-D order (left of any position is the previous letter, wrapping around).
Two different switches: Major/Minor keeps the root and changes the notes (G major → G minor). Relative keeps the notes and changes the home (G major → E minor), and the boxes stay exactly where they are, only the colours swap.
How to read this map · start here if it looks like noise
The picture below is your whole fretboard, laid flat. Read it in this order and it stops being noise:
- The six rows are your six strings, and they're drawn the way you'd see them looking down at the guitar in your lap: the thinnest string (high e) is the top row, the fat low E is the bottom. Left to right is the nut out to the 15th fret; the numbers underneath are frets.
- Every dot is a note that belongs in the key. Nothing else is drawn, so if there's no dot, that fret is not in the key, so the map is already telling you what not to play.
- Colour tells you what kind of note it is. The bright dots are the root: home, the note the key is named after. The second colour is the relative root (the same notes viewed from their minor/major twin). White dots are the rest of the chord tones, and faint dots are the other scale notes that connect them.
- The shaded blocks are the five positions. Each block is one region of the neck where the whole chord and its scale sit under your hand without moving. There are only ever five, and they repeat at the 12th fret, which is the entire neck, covered.
- The circled notes are the chord itself: literally the notes you'd hold down to play that chord there, one per string, skipping any string you wouldn't strum. Everything else in that block is scale notes decorating those.
- Each block has two names. "A shape" describes the grip your hand makes (it's the open-A chord moved up), and "box 4" is what a scale player calls the same region. Same place, two vocabularies, and that's the whole trick, and it's why chords and solos stop feeling like separate subjects. (Concretely: open position in G major is at once the G shape and box 1 of the pentatonic you already know as Em.)
- Tap any block to dim the rest and study one position on its own. Switch Show to see just the chord tones, the pentatonic, or the full scale in that shape. Change the key and the shapes slide; they never change relative to each other.
Why this is worth the effort: nobody invented CAGED. It falls out of how the guitar is tuned (mostly fourths, with one third between G and B) so those five shapes exist whether anyone names them or not. Learning this isn't memorising someone's system; it's discovering something that was already there, the way maths is discovered rather than made up. What it buys you:
- You stop being stuck in one place. Any chord can be played in five spots, so you take the one that's near where you already are.
- Your solos land in the right notes, because you can see the chord inside the scale shape you're already using.
- Changing key becomes sliding, not relearning. The shapes are the same, they just start at a different fret.
- Five shapes is the entire fretboard. Learn these and there is no part of the neck left that's mysterious.
Only two boxes reach two octaves
Worth noticing, because it changes how you hunt for the root: of the five shapes, only the E and G shapes carry the root across two octaves. The other three give you one octave and put the root somewhere in the middle.
| Shape | Roots sit on | Root span |
|---|---|---|
| E | low E · D · high e | two octaves |
| G | low E · G · high e | two octaves |
| C | A · B | one octave |
| A | A · G | one octave |
| D | D · B | one octave |
Why: the two E strings are the same note two octaves apart, so any shape with a root on the low E gets that root back on the high e for free, and E and G are the only two open shapes whose root sits on the 6th string (C and A start theirs on the A string, D on the D string). Nothing was designed here; it falls out of the tuning.
What to do with it:
- In the E and G boxes you can run root to root across two octaves without leaving the shape: start home at the bottom, land home at the top. That's why box 1 (the E shape) is the one everyone learns first and the one that feels most resolved to solo in.
- In the C, A and D boxes the edges won't hand you a root. They're mostly on the A and B strings, so in three shapes out of five, finding home is a skill you drill, not something the shape gives you.
- Practical drill: pick a box, play only its roots, say the note name out loud. Two of the five will feel obvious; the other three are the ones actually worth your practice minutes.
Leaving the box · three things that only matter once the five shapes are under your fingers
One box is wider than the other four
Four of the five boxes sit inside four frets. Exactly one needs five, because one string's pair of notes reaches back a fret further than the rest. In a major key that's box 2, the D shape; in a minor key it's box 3, the Cm shape. Those are the same shape wearing two names, which is the two-homes idea again: G major box 2 and E minor box 3 are the same frets.
Worth knowing because it stops you second-guessing your hand. If one box feels like a stretch and the rest don't, you have not mis-learned it. That box is a stretch.
Fours cross the reaching string eight times going up and eight coming back, which is how a stretch stops being something you brace for.
The boxes overlap, and that overlap is the door
Neighbouring boxes are not laid end to end. They share a fret or two, and those shared notes are the only place a phrase can cross from one to the next without a jump. In G major:
| Box | Shape | Frets | Shares with the next box |
|---|---|---|---|
| 5 | G | 0 to 3 | frets 2 and 3 with box 1 |
| 1 | E | 2 to 5 | frets 4 and 5 with box 2 |
| 2 | D | 4 to 8 | frets 7 and 8 with box 3 |
| 3 | C | 7 to 10 | frets 9 and 10 with box 4 |
| 4 | A | 9 to 12 | frets 12 and up: box 5 again, an octave higher |
So the standard way out of one box is not a leap, it's a slide on a single string through a shared fret. Play box 1, and on any string that carries a shared note, slide the note under your first finger up into box 2. Same finger, same string, new box.
Start with three, not five. The combination players actually live in is box 5, box 1 and box 2: the box below the root box, the root box, and the one above it. That covers roughly seven frets around home and is where most rock and blues phrasing happens. Boxes 3 and 4 are the same idea further up; they're worth learning after the first three are automatic, not alongside them.
Up box 5, slide on the top string into box 1, back down it, slide on the bottom string into box 2, up again, and the whole way home. You never lift out of the line, which is the part box practice alone never teaches.
Diagonal: the same scale, straight up the neck
A box keeps your hand still and moves your fingers. The other option is to keep your fingers still and move your hand: play the pentatonic diagonally, two notes per string as usual, but sliding up as you go, so the run travels about ten frets from its lowest note on the 6th string to its highest on the 1st.
- Fingering: first and third finger only, plus slides. Your hand changes position constantly, so a fixed four-finger shape fights it.
- Why bother: boxes are visible in your playing. Phrases that live in one tend to turn around at the same two notes every time, because that's where the shape ends. A diagonal has no edges to turn around at.
- How to learn it: pick a string, play the whole scale up that one string first, and only then spread it back out over two notes per string. The diagonal is the one-string version with the work shared out.
This is not a sixth box and it isn't a CAGED shape. It's a route through the ones above, which is exactly why it's worth having: every box you already know is a place it passes through.
Ten frets from the lowest note on the 6th string to the highest on the 1st, and back. Play it with the first and third finger and let the hand shift.
One scale, two homes
The same notes have two centres of gravity: land phrases on the key root and it sounds like the key; land on the relative root (three frets down for a minor, three up for a major) and the same box turns into its relative major/minor. Not two scales to learn, but one scale with two front doors, drawn inside the grips your hand already knows.
Circle of Fifths: The Map of Every Key
Twelve major keys arranged so each clockwise step is a perfect fifth up. Neighbors share 6 of their 7 notes, which is why they sound related. The inner ring is each key's relative minor (same notes, different home: the two-front-doors trick from the CAGED and scales sections, globalized). Tap any key to light up its complete chord family.
Fingerstyle
Fingerpicking turns any chord you already know into an accompaniment: the thumb keeps the bass going, the fingers roll the top three strings. Start with this loop and let it get boring before adding anything.

Which string does the thumb play?
This is the fact that unlocks fingerpicking, and nobody says it out loud: the thumb's string changes with the chord. Play the wrong bass and the chord sounds muddy for reasons you can't hear yet.
Every pair below asks for nothing extra to hold: the string is either already fretted by the shape or ringing open. No stretches, no thumb hooked over the neck. If your fingers can make the chord, they can play the bass.
| Chord | Bass 1 (the root) | Bass 2 (alternate with it) |
|---|---|---|
| Em | 6th string, open: E | 5th string, fret 2: B |
| Am | 5th string, open: A | 4th string, fret 2: E |
| C | 5th string, fret 3: C | 4th string, fret 2: E |
| G | 6th string, fret 3: G | 4th string, open: D |
| D | 4th string, open: D | 5th string, open: A |
| E | 6th string, open: E | 5th string, fret 2: B |
The rule under the table: bass 1 is the chord's root, bass 2 is another chord tone lower than the melody strings, usually the fifth. That's why they never clash.
Alternating bass: the actual unlock
Now make the thumb move. Thumb on beats 1 and 3, fingers on 2 and 4: p i p m. It sounds like two instruments the moment it's steady, and it's the engine under most acoustic playing you like.
Am C G Em
e|----------------|----------------|----------------|----------------|

A|--0-------------|--3-------------|----------------|--------2-------|
E|----------------|----------------|--3-------------|--0-------------|
p i p m p i p m p i p m p i p m
Say it out loud while you play: bass, finger, other bass, finger. When that's automatic your right hand has a motor, and everything else is decoration on top of it.
The pinch
Thumb and a finger strike together. One move, two voices, and the cheapest "how are you doing that with one guitar?" trick there is. Pinch on beat 1, then let the alternating bass carry on:
Am C e|--0-------------|--0-------------| B|-----------1----|-----------1----| G|-----2----------|-----0----------| D|--------2-------|--------2-------| A|--0-------------|--3-------------| E|----------------|----------------| p+a i p m p+a i p m p and a strike at the same instant, then the bass keeps alternating underneath
Right hand, set up once
- Thumb in front of the fingers, not tucked behind them: keep it closer to the headstock so it never collides with your index on the way down.
- Fingers stay over their own strings: i on G, m on B, a on high e. Assign them once and stop re-deciding mid-song.
- Small motions. The string only needs a few millimetres. Big plucks are why fingerpicking sounds frantic.
- Nails optional. Flesh is warmer and more forgiving; nails are brighter and louder. Either works, just don't switch weekly.
- Let the bass ring. Don't damp it chasing the next note; the sustain is what makes it sound full.

💡 Practice Tips
- Slow is fast. Practice slowly and accurately before building speed.
- Use a metronome. It builds internal timing that's hard to develop otherwise.
- Short daily sessions beat long weekly ones. 15 minutes every day > 2 hours once a week.
- Focus on transitions. The hardest part of chords is switching between them smoothly.
- Record yourself. You'll hear things you miss while playing.

Barre chord ladder (how to actually learn barre chords)
Never start with the full barre. Climb:
1. Power chord B5 (A-string root, 2 fingers)
2. Mini-Bm, top 3 strings only
3. 4-string Bm, barre just strings 1–4 at fret 2
4. Full A-shape barre, only when 3 is clean.
Cue: squeeze only at the moment of the strum, relax between. Death-grip is why barres hurt and buzz.
One-minute changes
60 seconds, one pair of chords, count clean changes, write the number down. Beating yesterday's number is the whole game. Good pairs, each as a drill file:

Playing with someone else
The fastest way to get good is a second guitar. Two frameworks that work from day one:
12-bar blues in E, the eternal duet. The newer player plays roots only (open E, open A, 2nd-fret B on the A string), one confident note per bar, while the other solos from E minor pentatonic. Rule: maximum 3 notes per phrase, then breathe. Phrasing beats shredding. Swap roles every cycle.
E (4 bars) A (2 bars) E (2 bars) B (1) A (1) E (2)
Shuffle pattern, all down-picks (palm-mute it and it's proto-metal):
E: A|-2-2-4-4-2-2-4-4-| A: D|-2-2-4-4-2-2-4-4-| B: D|-4-4-6-6-4-4-6-6-|
E|-0-0-0-0-0-0-0-0-| A|-0-0-0-0-0-0-0-0-| A|-2-2-2-2-2-2-2-2-|
Practice file: the 12-bar shuffle (the rhythm half; your partner plays roots)
Chord/lead split. Pick any 3–4 chord song: one plays the loop, the other noodles in the matching pentatonic box, swap each verse. Calling out the roots as they pass doubles as ear training.
