The Alligator

Bar 1. G major, Drop C tuning, 4/4 at 120 BPM. The bass plants G1 on the downbeat. The rhythm guitar strums G2 plus A3 plus D4, three open strings on Drop C, no 3rd anywhere in the voicing. The lead guitar sustains F♯4 above, the M7 of G. The whole top end is held G + A + D + F♯ for two full bars, an extended-color stack with the major third deliberately absent.

The chord is Gadd9. The 9 is on top (A3), the 5 is in the middle (D4), the root is at the bottom (G2 plus G1 bass). The M7 (F♯4) rings from the lead guitar. The song opens with one of the brightest possible voicings of the tonic and lets it ring. No drums. No vocal.

Bar 3 the bass drops to B♭1 and the rhythm guitar shifts to G2 plus F3 plus B♭3 plus D4. The same G stays on the bottom. The A becomes F. The D stays. B♭ enters as the new chord root. The stack reads as B♭6/9: B♭ root, D third, F fifth, G as the 6, A as the 9. The voicing has no minor 3rd of B♭ (no D♭), no 7th, no obvious B♭ triad shape. The rhythm guitar holds the same hand position and lets the bass redefine the chord underneath.

Bar 4 ends with a 32nd-note bass walkdown: B♭1 to A♭1 to G1, three quick steps over the last sixteenth of the bar, landing on G for the downbeat of bar 5. The walkdown is the seam that stitches the B♭ section back to the G section. It fires at bars 4, 8, and 10 across the whole song. Three walkdowns, all 32nd notes, all in the same position of their respective bars.

Bar 5 the vocal enters. The pitch is B3. Over Gadd9 it is the M3 of G, the chord tone the rhythm guitar has refused to play in the voicing. The voice carries the third. The instruments hold root, 5, and 9. The arrangement decision is the same one Shiner uses across the whole album: power-chord-extended voicings in the band, the M3 in the vocal.

Bar 7 the chord drops to B♭ again. The vocal stays close, moving to C4. Over B♭6/9 the C is the 9 of B♭. The voice has shifted from M3 over G to 9 over B♭. The melody barely moved (B3 up a half step to C4) and the harmonic identity of the held note pivoted.

Bars 5 through 8 are verse cycle 2 with vocal. Bars 9 through 12 are the chorus. The chord cycle is the same. Bar 9 holds Gadd9. Bar 10 moves to B♭6/9 with the walkdown at the seam. Bar 11 returns to Gadd9. Bar 12 closes the song on G/B, the I chord in first inversion. The bass walks from G to B for the final beat. The rhythm guitar voices B2 plus D3 plus G3, the G triad with the third in the bass. The lead F♯4 holds. The vocal stays on B3.

The whole song is 12 bars. Eight bars of verse split into two four-bar passes (instrumental, then with vocal). Four bars of chorus that compress the same I to ♭III alternation and end on a first-inversion cadence. The form is one of the tightest in the Shiner catalog. The song knows what it is and does not pad.

The central reharmonization device is the rhythm guitar fingering. G2 plus A3 plus D4 is three open strings on Drop C, easy to hold, easy to ring. Over the G bass it reads as Gadd9 (root, 9, 5). When the bass shifts to B♭, the guitarist adds F3 and B♭3 and the stack becomes B♭6/9 (with the old G now reading as the 6, the old A now reading as the 9). The hand barely moves. The chord identity flips because the bass moved.

The vocal pivot from B (M3 of G) to C (9 of B♭) is a one-half-step move that reframes the chord underneath. The pitches B and C never leave the song. Over G the vocal is M3 or sus4. Over B♭ the vocal is 9 or M3. Over the final G/B the vocal stays on B as the root of the bass note and the M3 of the chord above. Two notes carry three different scale-degree functions across the song.

The bass walkdown B♭ to A♭ to G is the song's only chromatic gesture. It happens three times (bars 4, 8, 10) and never anywhere else. The A♭ in the walkdown is the only ♭2 of G that appears in the song. Three 32nd notes at 120 BPM is roughly 60 milliseconds per step. The walkdown is fast enough that the ear hears it as a single descending gesture rather than three separate chord changes. The harmonic effect is a smooth slide from ♭III back to I rather than a chord substitution.

The arrangement strategy: bass and rhythm guitar voice only roots, 5ths, and 6/9 extensions. The lead guitar holds F♯ as the M7 of G across most of the song. The vocal supplies the M3 of G (B) and the 9 of B♭ (C). The vocal third combined with the lead M7 fills out the chord above the bare-fifth bed. When the vocal is silent in verse cycle 1, the lead F♯ alone is the only color tone above the power-chord stack.

An earlier automated chart identified the verse as Gm9 to B♭maj9 because the analysis included the vocal B and C in the chord-detection pool. With the vocal stripped, the rhythm guitar reads as Gadd9 (not Gm9, because there is no B♭ in the G chord voicing, the B♭ only appears when the bass shifts). The corrected chart shows Gadd9 to B♭6/9 across 12 bars. That correction matters because Gm9 would imply the song is in G minor, when in fact the entire chord vocabulary stays in G major.

Take this into your own writing. Find a chord shape that works as add9 over one bass note and as 6/9 over a bass note a minor third up. Write a 12-bar form that alternates those two chords (two bars each) and ends on a first-inversion cadence. Withhold the M3 from the rhythm bed. Put the M3 in the vocal and let the voice define the chord identity. Add a fast bass walkdown at the seam between the two chords for the chromatic glue. Twelve bars is enough. The song is the form.
