Big breakthroughs today on “Castles Made of Sand,” which has for years been at the top of my “I can play it fine but it just doesn’t make sense” list: the strange Bb (real pitch A; fret 6 on the low E string) in the intro and choruses is played with thumb, and the even stranger F (fret 8 on A string) is played with ring finger. If this is true, which I’m increasingly confident it is, the whole bizarre passage makes a lot more sense, both technically and (bear with me) harmonically.
Jimi’s thinking of the whole song in relation to the droning open G string. I think it’s very likely that the sliding, ambiguous add9 chords in the intro and outro were the first part of the song he came up with, and he built the whole song structure based off of the possibilities that offered him. He’s looking at that clean section of the “Castles” intro (after the reverse guitar and chime-y chords, before the verse starts) as chords:
Intro/Chorus
G major: walk it up through the common bass arpeggio.
B minor: standard pentatonic box 1 stuff… until—
C6sus2: yes, I am proposing a chord nobody has ever considered here, and I’ll justify it below.
A minor: more pentatonic box 1 stuff. I think the C commonly notated on fret 3 of the A string here is misplaced in tabs, and I’m betting it was on fret 8 of the low E, played with Jimi’s ring finger.
Bb6sus2: same as C6sus2 above. (You could also spell these as e.g. C6/9 (no 3rd) if you’re jazzy.)
[[G major
Bb major
C7 (another new one I’m proposing)]] x2
The [[double bracket]] section is what I’ll refer to as the “turnaround.” It always repeats twice, except for the solo, where it forms the entire background on repeat.
Verse
F sus2 (he never plays a 3rd at all over F in the whole song)
A minor
E minor
F
C
G [[turnaround x2]]
Repeat: this is my best guess at how Jimi was thinking of the harmony in this song.
The weird 6sus2 chords:
I think Jimi built these based on a hand-position shift that’s available to him via using his thumb. One potential reason he worked so much within the common pentatonic box 1 is that it’s easy to make the matching minor chord without altering the fretting hand position. If we consider a Bm7 barre chord in his system to be:
e 7(index finger barre)
B 7(index finger barre)
G 7(index finger barre)
D 7 (index finger barre)
A 9 (ring finger)
E 7 (thumb)
—then my proposed chord concept of C6sus2 is as easy as just shifting the thumb and ring finger up a single fret together, resulting in this:
e (mute)
B (mute)
G 7(index finger barre)
D 7 (index finger barre)
A 10 (ring finger)
E 8 (thumb)
This is EXACTLY the chord shape that he undeniably uses for what I’m labeling Bb6sus2 at the 0:14 mark in the song. I’ve almost always seen this chord played by others fingered as
G 5(index finger barre)
D 5 (index finger barre)
A 8 (pinkie)
E 6 (middle finger)
—which is a perfectly good, comfortable way to play it verbatim. It makes sense in every context, except for how the hell did Jimi come up with that?
Well, if my guess is right, then it’s easy to see how he’d come up with it. He just kept his index finger still, and shifted his thumb and ring finger up a fret, basically raising the power chord at the bottom of the chord voicing by a half-step.
I bet Jimi was NOT thinking of them as “6sus2” chords verbatim, although I think he did have a fairly sophisticated harmonic vocabulary, via his time with Little Richard and the Isley Brothers. I’m betting he was thinking of them more in terms of “lifting the A minor up to Bb, but keeping the A minor notes in the middle strings.”
Maybe, but WHY would he come up with that?
I’m going to revisit the overall harmonic structure again:
Gmaj (root/I) > Bm (iii) > C6sus2 (IV)
Keep this I-iii-IV in mind for later. Then:
Am (ii) > Bb6sus2 (bIII) > [[turnaround]] [[Gmaj (I) > Bbmaj (bIII) > C7]] x2
Okay, that C7: it’s fingered identically to what I’m calling Bb6sus2, with one exception: the A string is muted.
“C7:”
e (muted)
B (muted)
G 5 (index barre)
D 5 (index barre)
A (muted)
E 6 (thumb)
So I WOULD call it the same chord, except for this: at the end of the turnaround, it sets up a return to the verse section, where the chord is F major (thus, a V7 > I resolution / cadence), and when this happens, Jimi never plays the 8th fret note on the A string. He mutes it every time he’s going to play F next, and he plays it every time he’s going to play G next. Maybe a coincidence! But whether it is or not (and I think it isn’t), it does have that effect.
I’m going to have to revisit this later tonight after I’m done teaching to talk about what the verse does. Quick version:
Fsus2 (I) > Am (iii) > imply C with low E string note (IV)(new key center I) > Em (iii) > imply G (IV)(new key center I) > F (bVII) > C (IV) > G (I)
So it’s a stack of overlapping I > iii > IVs. Neat!
Tangent: another detail that I think arguably supports these harmonic ideas:
The bass drops out completely in the choruses, where this harmonic motion would be harder to follow, and it just sits on the G in the turnaround at the end of each half of the verses, and also simply sits on G for the duration of the entire guitar solo, while the rhythm guitar repeats the turnaround motif. I think this is probably due to Noel Redding not knowing quite what was going on in those sections, and Jimi likely not being able or willing to explain it to him. (They notoriously didn’t work together well in the studio, often due to Jimi’s lack of clear communication skills about what he wanted; during the Electric Ladyland album, Jimi would reportedly get Noel to do so many takes that Noel would leave in frustration, at which point Jimi would go and record the bass lines he wanted himself.)
