Interesting thread… Generally song comments have been about mixing tips, recording techniques, plug-ins, effects, performance, musical style, et.al…. or just fun. Not too many comments getting in the weeds on music theory unless someone is way out in left field or the composer is asking for guidance. This song is certainly not harmonically incorrect and does not sound remotely dissonant or wrong in any way. If it were there might have been other comments to that effect.
My personal comment and some of the others were about the swing or lack of swing between the Drums, Bass and Piano. I can tell you musically I didn't hear anything "wrong" and to the contrary I think it is pretty cool. I would just loosen it up a bit so it just swings a little, everything else is quite good.
There are many ways to skin a cat chordally and it is ultimately up to the artist to determine the best route to express the song to its’ full potential. Do I use major, minor, altered chord, triton substitutions, Should I go Dm7, G7, C or Dm, Ab7, C, or Dm7, Db7, C or Dm7, G7b5 to C or Dm, G13b9 to CMaj7? Doesn’t much matter as long as everyone is going in the same direction.
Many new people here, so maybe the status quo is changing, however, I personally wonder how productive comments about chord choices in the Songs Forum are unless someone is specifically asking for assistance or the choice they have made is obviously bad? These theory discussions have generally been reserved for the Techniques forum. The chord choices in this song are maybe not pop-oriented, canned rock progressions but they are definitely interesting. Reminded me a bit of some of the early Steely Dan. They certainly made a career on using the 4
th as the chord root. G/C or Cmaj9 if you prefer, and using passing tones in the process.
There are plenty of examples in music where half step intervals within a chord produce interesting harmonies whether they are at different octaves or the same octave.
Anyway, sorry to derail your thread, I just wanted to say I am not part of the “we are voicing our opinions” about your chord choices I like the song and thought it was pretty cool.
