You already put in the work naming all of them
Renamed those 37 chords

For that chord tied into m1/9, I think the Eb is a D there, but you can leave it if you want.
Oh yeah you're right about that. I feel like I had D there at some point but changed it for unknown reasons
m1/9 LH beat 3.5: There's an Eb 8th note here (middle of staff) instead of just a held quarter note.
Yup I missed that one
m7 LH beat 3.5: Bn should be Cn.
Yeah that does sound right
m8 RH beats 3-4: Since the melody takes over at beat 3.5, you might want to consider making beat 4 just Eb instead (since it's the same as the pickup measure).
The voice leading sounds a little weird to me with that one. With an Eb, the downward slope leads your ear into the D instead of the melody's Bb. I think I'm gonna leave it be
m13/31 beat 4.5: This chord is actually a Bbsus at first, resolving to Bb on beat 3 of m14/32. There's no D in the accompaniment before beat 3.
There's actually a
D in the saw through those four beats, but judging from the progression at m31 I think they were going for a Bbsus there so I changed it
m21 RH: I would move the F to G instead, since it's actually an Fm9 chord and the F is doubled in the bass.
Yeah I think that sounds good
m25 RH beat 4.5: Wouldn't it make more sense to use the Gn grace note here since that's the top voice?
When I tried playing it I found it really difficult to roll 4 into 3+5 with 4 on white and 5 raised on a black key. It's a lot harder to move 4 and 5 independently, so using the index finger for the grace note and rolling upwards into the dyad was much easier for me
m33: This chord is missing a B (G#m9 chord).
I can't hear a B here no matter how hard I try. I can
maybe hear something very subtle in the register above the melody, but it could easily just be overtones or something. That said, G#m9 does make the most sense over any chord options which omit the B, but I don't think it fits well with the particular voicing here. Putting a B on the bottom is a pretty large and awkward stretch, and putting it on the top next to the Bb causes a cluster of dissonance near the melody. I think it's best to leave it out even if the chord symbol doesn't quite match
m34 beat 3: This chord on beat 3 adds an Dn, creating a C#7b9 sound.
I do think I can hear this one. Added it with an additional chord symbol
m37/41 beat 1: This chord is also missing a B (G#m11). I probably would go with B-C#-F#-A#, bottom to top. You don't need to double the 9th (A#), and the 5th (D#) isn't required.
Again, I maxed out my deductive tools here and I can just barely make out a B in m37 with some frequency isolation. At the very least the C#-F#-A# completely dominate the sound, so including the B in any available inversion adds a lot of extra tension that I don't hear myself. I'm going to leave it out like in the other places
m37 beat 4.5: This C#7b9 chord is missing the Dn. The Dn plays throughout m38.
Oh yeah, this fills a bit of a gap I was hearing between the B and F. That said, I moved beat 2 to a C# instead of continuing the D because of the accompaniment that plays higher than the melody normally. I moved it down to make the main melody line stand out
m41 beat 4.5 RH: The flat 9th (B) is pretty prominent in this chord, so if you want you can move the bottom C# to a B (either up or down).
I originally took the B out because the low B was a big stretch, but I don't think it sounds too bad up an octave. Added the higher one
m45 beat 1 RH: This chord is B#m11, so you can include the 9th (Cx) if you want.
I left that pitch out because the fingering makes a weird claw shape that's kind of awkward to form coming out of the eighths in the measure before
m47 LH beats 3-4: I hear the bass going B-F#-B-C# here instead of B-G#-A#-C#.
Oh yeah I dropped that part into the bass from a run that happens in the upper register because I felt like the normal bass fifths sounded thin with only the F#-A# dyad in the RH. I think I just left too much out of the RH chord though, so I added a D# to the RH and swapped in the normal bass line
m48 LH beat 3.5: The bass restrickes on C# here, so it's a 3-note pickup back to m1.
I originally had a 3 note pickup there, but the main bass either doesn't restrike or plays
extremely legato. That said, the snare hits clearly signal 3 notes so I think it still works to add in the extra note. On top of that, listening back from this comment made me realize there are actually two basses in there, one is just waaaaay back in the mix. The secret bass plays the 3 note pickup too so I think it's the right change
m33-end: This might work better in Gb major, not only since it keeps everything in flats, but also because of how it resolves back to Eb major. In m45-48, you'll notice it has roughly the same progression as m13-16, which is written with flats there. Writing it in Gb will remove a lot of those double sharps.
Yeah I changed it to Gb. I changed the chord symbols before editing the key and looked at the accidentals again after, so hopefully everything is still spelled right
Oh yeah and THANK YOU thank you for reviewing the chords. This was the first time I've tried to name chords and I was hoping someone might pick them up for review even though I hid them. I learned a ton about chord notation from your comments, you da bes
