One change. Two chords. Twenty-four ways to make it trippy. Scales, moves, techniques, stabs — chomp through them one at a time, record every pass, keep the keepers. The loop is the laboratory; the recording is the result.
Loop it. DAW, looper pedal, whatever. Four bars of E, four bars of A7, forever. Tempo: 66–80 bpm, swung or straight — your call. Every idea below gets one pass through the loop. Record everything. Judge nothing until playback.
Before the scales — the whole neck at a glance. Every note over the E tonal centre, coloured by how many of the seven scales in this pack contain it. Each dot shows the note name and its interval (relative to E). Hot notes are safe anywhere — they live in almost every colour. Cool notes are the characteristic tones — rarer, spicier, the ones that define a single scale. Play the hot notes freely; land the cool notes on purpose.
E, B, D, F♯, C♯. Root, 5th, ♭7, 2nd, 6th. These live in nearly every scale here — they're home base. You can hang on them over both the E and the A7 without thinking. Safe landing notes for every phrase.
G♯, A, G, A♯. The 3rd, 4th, ♭3, and ♯4. These are the blues and fusion colour — the G/G♯ rub, the ♯4 float. Present in several scales but not all; they tilt the mood.
C, D♯, F. The ♭6, 7th, ♭2. These barely appear — mostly from the whole-tone and altered scales. Maximum strange. Use them as passing tones or deliberate tension, then resolve to a hot note.
The density map above asks "how common is this note." This one asks the harder, more useful question: "what job does this note do over the actual chords?" Every note is coloured by its harmonic function over E7 and A7 — from the safest chord tones (cool) to the spiciest outside notes (hot). The two guide tones of each chord — the 3rd and ♭7, the notes that define the chord and pull the ear — get a bright ring. The roots get an amber ring. Each cell shows the note and its function label (R, 3, ♭7, 9, ♯11, ♭9, 11, etc.), not just an interval.
E7 → G♯ & D. A7 → C♯ & G. The 3rd and ♭7 of each chord. These are the notes that define the chord and voice-lead into the next one. Land phrases on these and you always sound "inside," even over the strangest scale. The pros aim here.
E, G♯, A, C♯, D, G. The four guide tones plus the two roots. These six notes are consonant somewhere in the vamp and never badly wrong — the harmonic bones of the whole E→A7 loop. Your bomb-proof target set.
C and F are the hottest — dissonant over both chords (♭9, ♭13, ♯9). And watch the avoid notes: A over E7, and D over A7 (the 11 clashing with the 3rd). Spicy isn't wrong — it's tension you resolve to a guide tone.
Take the spice map and boil it down to three scales we invented for this exact vamp. Every one of the twelve notes falls into one of three buckets by how it behaves over E7→A7. These aren't standard scales — they're the harmonic reality of the E→A7 loop, split into a safe scale, a spicy scale, and an avoid scale. Practise them as three separate colours you can dial between.
Every chord tone of both chords, fused into one scale — including all four guide tones (rust: G♯ & D for E7, C♯ & G for A7). It has both thirds (G and G♯), so the major/minor blues rub is built in. You cannot sound wrong on these notes. This is your home base — solo entirely from here and it's bomb-proof over the whole loop.
The usable tensions — the notes that sound outside-but-hip. F♯ is the 9th over E7 and the 13th over A7 (sweet). A♯ is the ♯11 (the Lydian-dominant float). D♯ is the ♯11 over A7. Small on purpose — the safe scale already ate most of the neck. These three are your colour injections: drop one in, then step back to a safe note. A little goes a long way.
The two notes that are dissonant over both chords. C is the ♯9/♭13 — the milder of the two, usable as a bluesy Hendrix-style tension if you resolve it fast. F is the ♭9 — the real danger; sit on it and the vamp sounds broken. Not literally forbidden — maximum tension. Land here only as a deliberate outside stab, then resolve to a guide tone immediately. The value of knowing these is knowing what to resolve away from.
Pass 1: solo using only the Safe Zone scale for a full loop — prove to yourself it's bomb-proof. Pass 2: same, but allow one Spicy note per phrase, always resolving back to a safe note. Pass 3: add a single Avoid note as a deliberate outside stab, resolved instantly to a guide tone. By Pass 3 you're controlling tension on purpose instead of hoping — which is the whole game. Record all three and listen for the moment the spice lands right.
One per pass. Don't mix scales within a pass — commit to the colour and live in it. The trip factor goes from 1 (familiar) to 5 (alien). All rooted on E.
The straight-ahead dominant colour. D (♭7) against G♯ (3rd) is the sound. Over the A7 it becomes A Dorian — same notes, different gravity.
Minor over major. The G♮ rubbing against the G♯ in the chord is the blues. Bend the G toward G♯ and never fully arrive — the bend IS the vocabulary.
The sweet layer. Swap to this mid-phrase after a minor pent line and it's the Magic Sam toggle from Session 06. C♯ is the 3rd of A7 — it sings over the change.
Your Session 01 home scale. The C♯ is the Dorian note. Over A7 it's perfect — C♯ is the 3rd. Minor feel with a major 6th = sophisticated ambiguity.
Mixolydian with a ♯4. The A♯ is the trippy note — it makes the E chord sound like it's lifting off. The Steely Dan scale. Underused in blues. The A♯ clashes gorgeously with the A natural in the A7 chord — use the tension, don't hide from it.
No gravity. No home. Pure float. From the Specimen Cabinet — the scale that repeats every 2 frets. Play it ascending over E and let it hang through the change to A7. The A♯ and C clash with A7's chord tones. Use sparingly: one whole-tone run per two choruses maximum.
Maximum tension for the A7 bars only. Every note is an alteration against the chord. Resolve back to E pentatonic when the E chord returns. The contrast between altered chaos on A7 and simple pentatonic on E is the trip — the weird is only weird because the normal exists next to it.
Layer these on top of whatever scale you're in. Each one is a texture or technique, not a note choice. One per pass — try the move, record it, move on.
Fret any note, curl it 25 cents sharp, hold. The beating between the slightly-sharp note and the open string underneath is sitar physics. Do it on the G♯ (fret 1, G string) over E — the major 3rd slightly sharp against the open E is gorgeous and unsettling.
Ring an open E chord. Bend the open B string behind the nut up to C♯ — the chord morphs from E to Eadd6 without your fretting hand moving. Then try bending the G to G♯ — Em becomes E major with one finger behind the headstock.
Volume to zero. Strum E. Swell in through the Broadcast into the BigSky. The chord appears from nowhere. Do it on the change to A7 — the A7 materialises like a ghost. The dry side catches the arrival; the wet side catches the tail. Two amps, one vanishing act.
Vibe on maximum speed, single notes on the high E string. The vibe chops the signal into rhythmic pulses. Slow the speed mid-phrase — the pulse stretches, the note starts swimming. Fast vibe = helicopter. Slow vibe = underwater. The transition between them is the move.
Touch 12 frets above each fretted note, pluck behind with the thumb. An open E chord becomes a music-box E chord an octave up. Through the BigSky on shimmer this is absurd. Do it on the E bars, strum A7 normally — the contrast between ethereal and earthy is the trip.
Play an entire phrase on just the G string, frets 0–12, sliding between every note. Never lift off. The slides create portamento that no scale run can. Through the Broadcast at noon the slides have a vocal, crying quality. One string, one voice, one long sentence.
Play any lead on the B and high E strings. Thumb hits the open low E on every beat. The drone anchors the weird. Same monotonic thumb from Session 02 but under trippy lead — the more alien the melody, the more the drone grounds it.
Play a simple E minor pentatonic phrase. Now replay it but randomly jump notes up or down an octave. The melody is the same but the intervals are huge and jagged. Thelonious Monk did this with piano. On guitar it means jumping positions mid-phrase — the physical leaps create musical leaps.
The D note (fret 10 high E, or fret 3 B string) with a pinch harmonic squeals and sustains differently from a regular note. The ♭7 squealing over a major chord is pure Hendrix. The Broadcast at noon gives enough gain for the harmonic to sing without needing the Thornicus.
Forget scales entirely. Play chromatically — every fret, ascending or descending — but SLOW. One note per beat. Through the Broadcast and BigSky, chromatic movement at slow tempo sounds intentional and cinematic rather than like a mistake. Land on a chord tone (E, G♯, or B) to resolve. The landing makes the chromaticism retrospectively intentional.
Play the pentatonic in parallel 4ths — two notes, same interval, moving up the neck. Frets 0/0, 2/2, 3/3, 5/5 on the B and E strings. The 4ths sound open and hollow, like church bells. Slide between them — the parallel movement is the sound of McCoy Tyner's piano applied to guitar.
Pick one note as fast as possible — flat-out tremolo — and let the BigSky turn it into a wash. The individual picks disappear. It becomes a sustained tone with texture. Stop suddenly. The BigSky's tail continues without you. You've created a note that plays itself.
Play a phrase on low gain mode. Stomp the right footswitch mid-phrase — the same phrase is suddenly in high gain. The texture changes under the notes without the notes changing. One guitar becoming two guitars mid-sentence. The audience hears a gear shift; you moved one foot.
Drop these between lead phrases as punctuation. One stab, let it ring, back to lead. The stab is a comma, not a sentence.
The Hendrix chord. The trapdoor from Session 01. Stab it and let the G♮ and G♯ fight each other.
E Mixolydian in one shape. The D on top against the E bass is the ♭7 tension. Open strings everywhere — it rings for days.
Pure tension-release. The A resolves to G♯. Zero effort, maximum effect. Let the sus4 hang for a full bar before resolving.
For the A7 bars. The open B is the 9th. The open high E is the 5th. Three open strings = huge ring. Let it sustain into the E change.
One pass per idea. E to A7, four bars each, loop forever. Try it. Record it. Move on. Don't judge anything until playback. Some of these sound terrible in the room and beautiful in the recording. The recording is the truth.
One scale per pass, in order 1→7. Commit to the colour. Don't mix. Live in each one for a full loop. By pass 7 (A altered) you'll know which colours your ear likes and which ones you need more time with.
One move per pass. Use whatever scale felt best from Phase 1 as the note source. The move is the variable, not the notes. If a move doesn't work on first attempt, give it 2 minutes then move on — come back to it later.
One stab chord per pass. Lead between the stabs — use your best scale + your best move from Phases 1–2. The stabs break up the lead and create structure. By pass 24 you've got a vocabulary.
One final pass. No rules. Use whatever you want from all 24 ideas. Record it. This is the take. Listen back and circle the moments where something happened that wasn't planned — those moments are the vocabulary that's actually yours now.
Phase 1 (scales): low gain, 9 o'clock. Let the scales speak without distortion colouring the intervals.
Phase 2 (moves): low gain, noon. The germanium adds texture to the techniques — the curls, the slides, the pinch harmonics all respond to the extra saturation.
Phase 3 (stabs): low gain, noon. The stab chords want snap and body.
Phase 4 (free take): your call. Switch modes mid-take if the moment asks for it (Move 20).
BigSky: cloud or shimmer for the trippy passes (whole tone, altered, harp harmonics, tremolo wash). Hall or plate for the straighter passes (Mixolydian, pentatonic). The reverb is part of the trip — change it between passes.
TimeLine: dotted-8th for the trippy passes (the rhythmic delay adds another voice). Off or slapback for the straighter passes. Reverse delay for the volume-swell pass (Move 10) — the swell forward, the reverse behind it, two directions at once.
Move 11 only. Maximum speed to start, slow it during the phrase. Off for everything else — the vibe competes with the BigSky's modulation and the trip gets muddy. One modulation source at a time.
Record the dry and wet separately through the Babyface if possible — SM57 on the wet cab, AT2020 (or future OC16) on the dry cab. Some of these passes will sound better dry (the slides, the dynamics test). Some will sound better wet (the swells, the tremolo wash, the harp harmonics). Having both channels means you choose the blend per pass in the mix, not per session at the amp.
