Why does this bass line work?: Under the Milky Way

HI, cruising by and thought I'd jump in (I love transcribing stuff..) Heres my quick take without headphones.

You're on the right track, its the "musical grammar" thats may be tripping you up.


the opening harmony is:
Am |Am7 |Fmaj7 | G |

For the Amin and Fmaj7 chords use the open E str, and the Am7 and G use the G (3rd fret Estr).


Bass enters [playing the roots in the following progression:
≥≥≥≥≥(Gb) = that Gb is really named an F#
Am |D/F# |Fmaj7 | Emin7 |

D/F# = a D Triad in 1st inversion F#-A-D where the bass plays an F#.



Hope that helps!

 

I don't know how to explain it technically but it is used fairly often in music.

 

well, if the harmony in the guitar is constant (Am Am7 Fmaj7 G), the F# is just the an alternate bass note under a chord: The Chord Symbol would be Am7/F#

The F# is the 6th note in the scale:
A B C D E F# G A
1 2 3 4 5 6 7 8


What makes it work is register. The tension (or rub) between the F# and G is lessened because of the distance between the two notes. The F# in the bass is 3 octaves below where the added G on the guitar high E str is located.


Sometimes we dwell on the mathematics of music not adding up but in a true sense any two notes can harmonize and play together sympathetically. There will be varying degrees of tension, whether you prefer it or not is personal preference (or if it is stylistically, and culturally prevalent to the music you are creating).

 

This is only based on a quick cursory listen to the above video in post #2, but it sounded to me like when the bass enters the guitarist stops playing that second chord as an Am7 with the G note on top and instead starts playing a bog-stock D major triad...or possibly a D7, to retain the C natural from the previous Am chord. In either case I'm definitely not hearing that high G that was prevalent in the unaccompanied intro against the low F# in the bass; that would be really obvious I would think.

Either that, or these headphones suck.

 

Yeah it’s a really nice sound. The tension adds a little melancholy and mystery to the line.

The “I-VI”, or in this case i-vi root progression is a standard in many styles. (Ie “rhythm changes” chord progressions in jazz; like the flintstone’s theme). So depending on the bassists influences there’s a good chance it was a premeditated pick. A very musical choice all the same!

But hey noodlin’ has also created some great musical ideas as well!

 

That was my take last night too. TBH, I haven’t gone back to listen to it again with headphones after the first hearing.

If the guitar plays a D then the harmony is D/F#. If the guitar continues the same progression as the bass enters its an Am7/F#.

I beg the mercy of the council on my lack of due diligence

 

Sounds like the keyboard part uses the F# too.

 

HAH! this got me itchy so took a break grabbed some headphones.
yes, once the bass enters its |Am |D/F# |Fmaj7 |Em7 |

 

Off topic but I love playing Reptile by them.

 

I have loved this tune since it came out.
I think the Am with an F# in the bass (not a G flat) is an F# half diminished chord. F# A C E.
A G natural above that would be a chord I never heard about in music theory class, but I would call an F# half diminished 9th chord.

the melody hits a D when this chord is introduced, so it's kind of like a D11 without the root.

 

Wow, Haven't heard that one in a WHILE...... Nice pick

 

Shout out to that band for usually using the bass as the base of their songs (Steve Kilbey is bassist, singer, and primary writer), and for extensive use of Bass VI, also. Some interesting trivia that the subject album was produced by David Lindley.

 

I've been playing this all summer long. At my gigs. No real point to my comment other than I thought this was a somewhat obscure song. I'm glad people still dig it.

 

At the risk of sounding fanboyish, it's still a going concern, that band, with a huge catalog including an excellent release this year.

 

the guitarist is strumming with an open D string ringing in the chord so the bottom up gtr voicing would be:

E - 9th
C - 7th
A - 5th
D - root
A - 5th
F# - 3rd BASS

naming would be a D9/F#, but again the explanation of the (Gb) F# still stands as the 3rd of a D chord.

Theory is fun

 

Yeah and the whole thing is based on a A minor triad also with a descending bassline up to the E minor.
