Let say there is a chord progression something like

(C Major key)

C - Bb7 - F/A

From Bb7 (SubV7) which would probably go to A.
Will it be ok to resolute only the bass to A and go to a different chord that has the A note I could use for the bass and go to a whole different chord from A ?
(Something like D7/A , F7/A ?)

  • @topomorto I'm not in front of the keyboard so I didn't try it yet. But I'm asking it from a theoretical view – Hyun Yoo Park Apr 22 '18 at 6:02
  • I'm not in front of the keyboard - Fair enough :) - though your instrument will be able to answer this question better than we can! When I say 'Anything is always OK', that's perhaps a simplification - in some particular musical styles, some harmonic motions might be unexpected. So if you can specify a particular genre, we can give advice from that point of view. But in general it is true to say that even from a theoretical point you can do anything; anything is possible; all that's left are subjective judgements about whether it sounds good. – topo Reinstate Monica Apr 22 '18 at 6:07

    A quote we often use around here: "Music theory is created to DESCRIBE the way in which pieces are written, not PRESCRIBE how music should be written." Did someone tell you that music theory is there to tell you what you can and can't do? To quote RATM, "whoever told you that is your enemy". – topo Reinstate Monica Apr 22 '18 at 6:10
  • @topomorto - why, oh why, don't people understand not the theory itself, but what theory IS? – Tim Apr 22 '18 at 6:14

You ask 'will it be o.k?'

The biggest point is 'what will happen if you do?'

The main consequences will be : it sounds great and everyone will love it; it will grate and sound horrible and no-one will like it; something in between.

You will not lose a go, or be locked in jail.

Often, the bass notes will reflect the chord at the time, rather than vice versa, which is your proposition. And here, you suggest other chords with that A note contained within.

So, yes, it'll work. It won't be what the listener expects - C > Bb > ? more often does > F. But isn't that one of the points in music. The unexpected. 'I didn't see/hear that coming'. More to the point is - now you're out on a bit of a limb, let's see how you get back home safely.

The biggest criterion is how it sounds - to you and the listener. The 'rules', aka 'theory', as we keep banging on about, will try to explain what's happening, to help future readers. Guidelines, maps, if you like. But if everyone stuck to the well-trodden route, nothing new would ever get discovered.

EDIT: you ask if any chord will fit. Probably not any chord, but certainly any containing that A.
