You can probably name the chords in A major and grab the A, D, and E shapes without thinking. What's harder is turning that into something you'd actually want to play — a groove, a melody, a part. That's the gap this post closes.
Three Threads, one harmonic world. They all live in the same I–vi–IV–V neighborhood of A major: the first hands you the full set of chords, the second turns four of them into a rhythm part you can feel, and the third puts a melody on top of that same rhythm. Work straight through and you finish the week with a complete toolkit for the key — the harmony, the groove, and the lead — or jump to whichever Thread fits the hour you've got.
The complete diatonic 7th chords of A major — Amaj7, Bm7, C#m7, Dmaj7, E7, F#m7, G#m7b5 — walked in scale order as half notes and cadencing home with E/G# → Amaj7. These are moveable shapes, so the map you learn here works in every key.
A bass-and-stab comp through the A–F#m–D–E changes, voiced with the 7th chords from Thread 1 and played as clipped, syncopated stabs over a ringing bass — the chords from Thread 1 put to work as a real rhythm part.
A single-note lead melody over those same changes, outlining each chord with scale tones, climbing the neck for the D section, and walking home on a V→I landing.
Here's the part worth chasing: Threads 2 and 3 are two halves of the same piece — the "A OK Etude." Learn the comp, learn the melody, and eventually you can stack them and play the whole thing. Each Thread stands on its own, but the chords in Thread 1 are the vocabulary for everything that follows, so that's the place to start.
You know a handful of A-major chords. What you've probably never seen is all of them laid out as one map — and shown to be moveable shapes that unlock every other key. That's this Thread: a walk through all seven diatonic 7th chords in A major as half notes, in scale order, resolving home with E/G# → AMaj7.
Here's where these chords come from. Take the A major scale and harmonize it — stack thirds on top of each note until you've got four notes piled up. Two stacked thirds make a triad; three make a 7th chord. Do that on all seven scale degrees and a fixed pattern of chord qualities falls out, the same pattern in every major key: maj7 – m7 – m7 – maj7 – dom7 – m7 – m7b5.
In A, that gives you the complete vocabulary of the key:
AMaj7 — Imaj7 (the bright, settled home chord)
Bm7 — ii7
C#m7 — iii7
DMaj7 — IVmaj7
E7 — V7 (the dominant — the chord that wants to go home)
F#m7 — vi7
G#m7b5 — viiø7 (the half-diminished — m7b5 just means a minor 7th chord with its 5th lowered a half-step)
Don't labor over reading each one off the page — the graphic carries that load. What matters is that this is the whole harmonic family of A major in one place.
Spend a minute with the map you just saw. The note dots are color-coded by function — red is the root, green is the 3rd (or b3), blue is the 5th, purple is the 7th — so you can see, chord to chord, what's holding each voicing together. The finger numbers and fret positions are right there in each box. And here's the payoff that makes this more than an A-major chart: these are E-shape CAGED voicings, which means the whole pattern slides as a single block. Learn it here in A, shift the entire shape up two frets, and you're playing the diatonic 7ths of B. Slide it down — another key. You're learning the key of A and a portable system in the same study. This stack-thirds-on-each-scale-degree move is the engine behind every key — see The Music Matrix for the full picture.
One shape in that map is almost certainly new to you: G#m7b5, the chord built on the 7th degree. It's the correct diatonic seventh on the leading tone, it's genuinely worth knowing, and it's probably the only voicing in the set your fingers have never found. So learn it — its box is right there in the graphic. But here's the honest part: in real songs, that brittle half-diminished sound is rarely how you come home. What you'll actually hear on the way back to the I chord is E/G# — the V chord (E7) with G# in the bass. A slash chord like E/G# just means "this chord, but with a different note in the bass," and putting it in first inversion means the chord's 3rd, not its root, sits lowest. The reason it works is voice leading: that G# in the bass is the leading tone, sitting a half-step below A, and it pulls the ear home far harder than G#m7b5 ever could.
The key insight: The theory says the seventh chord on the 7th degree is G#m7b5. The music says use E/G# — the V chord with its leading tone in the bass. That G# climbs a half-step to A, and the ear comes home.
So that's the walk: AMaj7 · Bm7 · C#m7 · DMaj7 · E7 · F#m7 · G#m7b5, then the cadence E/G# → AMaj7. Play it in 4/4 with each chord held a full two beats — half notes, at ♩ = 80 to start, with room to settle anywhere from 60 to 90 BPM. The half notes aren't filler; they're the whole point. Let each chord ring its full two beats and you have time to actually hear what it is before the next one lands. Here's the whole study written out — notation and tab, the chord name over each pair, and the repeat that loops you back to the top:
Read it the way it's written: two chords to a bar, each held its full two beats, all seven qualities in scale order, then E/G# climbing the last half-step home to AMaj7. That listening is the real work here, more than the fretting. Move ear-to-ear through the qualities: the bright openness of the maj7s, the warm cushion of the m7s, the unresolved tension of the m7b5, the lean and pull of the E7. Don't rush the changes — let each chord bloom before you reach for the next, and resist the urge to speed up through the two unfamiliar shapes. Physically, those two are where you'll catch: getting cleanly in and out of the G#m7b5, and landing the E/G# with the G# bass ringing under the voicing. Take them slowly and on their own before you string the whole walk together. Then the last move is the payoff — E/G# resolving to AMaj7, that half-step bass climb from G# up to A, the sound of the entire map arriving home as music.
Loop the Soundslice until every chord change is clean, follow the video for the two hard shapes, and put the printed chart on your music stand. Play the walk over the A drone and you'll hear exactly how each quality sits against the tonic. These shapes move because they're built on octave-anchored root shapes — if you want to see those roots all over the neck, Know Your Octaves maps them out.
Once the walk feels settled, slide the whole pattern up or down the neck — same shapes, new position, new key — and you'll feel the moveable system click. This map is the vocabulary for everything else, too: these are the chords real progressions are built from. It's your toolkit.
Here's where those A-major 7th chords stop sitting still and start grooving. We're going to comp them — a bass root anchoring the low strings while a clipped chord stab pops off the beat up top, so one guitar starts to sound like a whole rhythm section. The part is the rhythm half of the A OK Etude: an 8-bar I–vi–IV–V loop in A, played as staccato stabs over a moving bass at a relaxed 100 BPM (start it at 60).
Here's the whole comp, start to finish. This is the rhythm half of the "A OK Etude" you've been building all week — Thread 1 gave you the chord vocabulary, and now those chords become a part. The eight-bar loop runs Amaj7 · F#m7 · Amaj7 · F#m7 · Dsus2 · DMaj7 · E7 · E7, landing home on a held Amaj7. Below is the complete part in one place, with the chord name over each bar so you can watch the I–vi–IV–V move go by.
The thing to notice is what every bar shares: the same rhythm — quarter, quarter, eighth, quarter, eighth — while only the chord shapes underneath it move. Learn that single rhythm once and you already know all eight bars; the lone exception is the very last bar, the held Amaj7 that lands the loop home. The rest of this Thread takes the part apart slowly — the cell that builds the groove, the feel that makes it lock, the chord move worth savoring, and the landing.
Start with the four voicings carrying it. You already met these as held shapes earlier in your week — Amaj7 (the I), F#m7 (the vi), Dmaj7 (the IV), and E7 (the V). Here they are again, lined up in playing order, before we put any rhythm to them.
Keep that reference close, but don't get lost re-learning the grips — these are the same voicings from earlier in your week, just put to work. The split that matters is this: the low-string root is what rings, and the upper grip (the D, G, and B strings) is what gets clipped. That division of labor — long bass, short stab — is the entire engine of the part. If you want to see where this I–vi–IV–V comes from, The Music Matrix shows how every key builds the same way.
Take the opening Amaj7 measure on its own. A bass root lands on the beat on the low E string and is left to ring. Then the chord answers on top — a quick, clipped stab on the upper strings that you cut short almost the instant it sounds. Bass long, stab short. That's the cell, and the whole groove is just this idea moving through the changes.
That tab cell is your core motion. Play it slowly and listen for two distinct voices: the bass note still humming underneath while the chord above has already gone silent. Staccato simply means each note is deliberately cut short — clipped, not allowed to ring. The trick (and Steve's first hard moment) is cutting the stab without choking the bass. Don't lift the whole hand. Ease the pressure on just the upper-string fingers — or lay a fingertip lightly across those strings the instant after you strike them — while your fretting of the bass stays put. The bass is your anchor; the stab is the accent that pops off it. This is the part that takes a few passes to feel natural, so give it those passes.
The key insight: The groove only locks when you do two things at once — land the stab off the beat, and cut it short. Syncopation puts the chord in the gap; staccato gives the gap room to breathe. Slow it down until both are true, then bring it up to speed.
Here's the second technique stacked on the first. Syncopation means the stabs land between the beats rather than squarely on them — on the "and" in the gaps, not on the pulse. So you're now asking your hands to do both jobs at the same time: place the chord off the beat and clip it short, all while the bass note keeps ringing on the beat underneath. Doing both at once is what makes this groove lock instead of plod.
Think of it as feel before technique. The bass marks the pulse, the stabs land in the spaces around it, and because each stab is clipped there's real silence between them — and that silence is what makes the part breathe. The two most common ways to kill it are rushing the stab back onto the beat, or letting it ring into the next one. Resist both. Let the chord sit a hair late and die a hair early.
So practice it honestly slow. Set 60 BPM, get the bass-and-stab cell clean and genuinely clipped first, and only push toward 100 once the clip survives the speed. The clip matters more than the tempo every time. If landing chords off the beat still feels slippery, the groundwork is in Syncopated Patterns Pt.1 — the offbeat-placement foundation this comp is built on. Loop the Soundslice to feel where the stabs sit against the pulse, and watch the video to see exactly how the right hand releases each one.
When the loop reaches the IV chord, there's a small move worth savoring. Across the two D measures, the hand barely shifts — two fingers move to recolor Dsus2 into DMaj7.
Watch the two notes move: on the B string the suspended 2nd (E) steps up to the major 3rd (F#), and on the G string the D drops to the major 7th (C#) — two small adjustments, the rest of the shape staying put. Musically, you're hearing the suspended tension settle into the warm major-7th color, and the comp uses it to add motion inside a single chord without you having to move anywhere. It's the kind of detail that makes a simple loop sound composed. Loop the Soundslice on these two bars to hear the color shift land.
The last two bars are where the loop resolves. The E7 (V) pulls home to the Amaj7 (I) — the move that closes the phrase and resets it to the top. Here it is on its own, zoomed in from the full tab you started with.
Let that E7-to-Amaj7 landing ring all the way out — this is the only bar where the upper grip isn't clipped, so the held Amaj7 feels like an arrival after eight bars of short stabs. When the bass anchors steady and the stabs pop cleanly off the beat through the loop, that lone guitar genuinely starts to sound like a band underneath you. Put the printed chart on your stand, run the backing track under it so you're comping into a rhythm bed instead of a click, and let the groove settle in.
You comped these four changes already. Now you put the song's top line right on top of them — same piece, the lead instead of the rhythm. The "A OK Etude" melody is a single-note line over A–F#m–D–E that outlines each chord in turn, climbs the neck for the D section, and walks home to land on A. The whole thing rests on one plain idea: a melody isn't random — every phrase sits on the chord underneath it.
Here's the full piece, start to finish. This is the lead part of the same "A OK Etude" you've been building all week — Thread 1 gave you the chord vocabulary, the comp put a rhythm under these changes, and now a single-note melody goes on top. Three parts, one piece. Below, the complete nine-bar line, with the chord name sitting above each bar so you can see which change every phrase belongs to.
That chord-name row above the staff is the whole point. As you learn the line, notice that each phrase belongs to one of these chords — A, then F#m, then D, then E, then home to A. Watching which chord is "active" under your fingers is exactly how single notes stop sounding like a scale and start sounding like a melody. The melody notes and the chords underneath them all come from one A major scale — The Music Matrix lays out how that connection works if you want the theory behind it.
Start with the opening phrase. Look at where the strong notes fall: they're drawn straight from the A chord, with stepwise scale tones stepping between them to connect the line. That's what "outlining the chord" means — you hit the chord tones on the beats that matter and let the scale fill the gaps. Play it slowly in the open-to-low region and listen for it.
In the cell you just saw, the descending idea over the first measures leans on A's chord tones — the line is built around them, not running past them. When the change moves to F#m, the melody quietly shifts its target notes to sit on F#m instead. You should be able to hear the chord change happen inside the single-note line, even with no chords ringing. Same region of the neck, same kind of motion — just new landing notes that belong to the new chord.
The key insight: A melody isn't random notes over a progression — every phrase leans on the chord underneath it. Hit the chord tones on the strong beats, connect them with scale tones, and a single-note line starts to sound like a song.
This is the hard moment of the piece. Over the D (IV) measures the line climbs up the neck into the fifth-to-seventh-fret region — a deliberate position shift, not a stumble. Here's the climb on its own.
Coach the shift musically, not just mechanically. Anchor the move on a target note, let the position change happen on a beat that has a little breathing room rather than rushing into it, and aim to land the high phrase cleanly. Getting back down is half the challenge — name it out loud to yourself, because the return for the E and final A is where most players trip. Don't let your volume or timing dip while the hand travels; the line should stay even and connected right through the move. If the up-the-neck move feels shaky, Sunrise is built entirely around shifting position cleanly across the full neck.
Over the E (V) measures the line descends and walks down to land home on the final A — the melodic V→I resolution, and the moment the whole piece resolves. Here's the walk-down and the landing.
Make that final A feel like an arrival, not just the last note you happened to play. It's a held whole note — let it ring all the way out. This is also where the second hard moment shows up in full: keeping the single-note line even and connected across string changes at tempo. Build it at 60 BPM until the line is genuinely connected, then bring it toward 100. Keeping a single-note line even and connected is its own skill — Norwegian Wood is a good place to keep building it.
Loop the line on the Soundslice, follow the video for the position shift, and put the lead sheet on your music stand while you work.
This melody and the comp are two parts of the same piece — once the line is clean, play the lead over the backing track and hear both halves of the "A OK Etude" lock together. Then shape it dynamically: lean into the top of the D-section climb, ease off on the walk home.
