Please can you take a look at this harmony and help me identify what is going on in bars 5 to 8 ?

at first i thought a Bbdom7 chord to An Amaj ( something along the lines of bVI7 to V but the G sharp has got me thinking about french 6ths and all kinds of madness !

thank you all.


< a d f > 1
<a cis e > 1
<g cis e >1
<d f a > 1
<bes d gis>1 %the Bb flat to a gsharp is a augmented 6th
<a bes ces>1
<bes d gis>1 %the Bb flat to a gsharp is a augmented 6th
<a ces e>1
< a d f > 1

yes. ces is supposed to be a csharp. my mistake.

but the score i am reading from definitely has an interval of a Bflat to a Gsharp. in the key of D minor , i am wondering what is going on .

just to clarify with es i mean flat and with is i mean sharp. thank you by the way.

Those augmented sixth intervals are just that - augmented sixth chords.
If it's preceding the V then it's just notated "+6". If it precedes another chord in the key it's just +6/x. Generally you find +6's with other notes, wherein they can be labeled italian, french, or german augmented 6th chords...but the aug 6 itself, resolving in that nature is the same thing, and has the same function in strongly preceding the dominant.

I was reading it wrong as well. So what jazz labeled as B7 are it+6's. But the cluster that's A Bb Cb...I don't know what I'd label that. I'd need to see the actual notes on a staff to see the voiceleading. In that sequence of chords it's probably just functioning as a deceptive resolution of that first +6 chord, which then appears again and resolves to the V then I64.

the harmony is from Mazurka - Pyotr Iiyich Tchaikovsky.

And just to confusions this that cluster is a A,Bb and C# in the music it is a single line. but as a cluster it as a satisfying crunch to it! ( i kind of hear it as A root /b2 (b9) and a major 3rd of An A Dominant 7th chord. But I think i am coming it from a Jazz perspective. Perhaps a classical approach might be different ?

In that case I'd probably just label it as a V. Depending on how it happens metrically, I'm assuming that first +6 partially resolves to that V chord, then goes back to the same voice, before it finally resolves outwards to an unaltered V chord.
