Not at all. You don’t have enough information at that point to make that determination.Stamped Records wrote:Take a really simple example; You start a song with a G, then you move to a C chord and at this moment in time our ears are telling us that C is our tonic.
How do you know it’s G and not Em, or if you’ve used a secondary chord and it’s neither in G or Em?Stamped Records wrote: But, if we play a D after the C, followed by G, the music tells us we are in the key of G.
Yes you could, you could have modulated to G Major.Stamped Records wrote:Had I chosen my 'scale' as C, I would never reach the point where I could drop the D chord to shift perspective to G.
The interval between the root of each of those chords in not a 5th, it’s a 4th.Stamped Records wrote:If I'd played Gm, C, well, because I'm familiar with the pattern of chords and intervals in the scales, I see root movement of a 5th from a minor to a major chord. Immediate instincts point to this being two chords in a ii,V,I sequence, so I know I can play with this for a while and add an F for a twist later on, or, relative that b**ch up and use a Dm.
Wouldn’t it be a lot easier to just learn to analyze harmony rather than limit yourself to the learning chord sequences one by one? This seems very limiting with no real benefit to it.
It would also mean you would know the term diatonic vi rather than “relative that b**ch up”, which communicates nothing of use to anyone
Every composer can wait to determine key after they have started playing, but I don’t think you are doing yourself any favors by actively avoiding making a decision on key. Knowing which key you are tending towards can help guide you in composing, particularly if you want to move beyond the chord sequences you have learned by rote.Stamped Records wrote:You could say that in these two examples, the key was the key from the beginning, but I prefer to leave the key undecided until the music finds it's own key.
I think you totally misunderstand the purpose of a circle of fifths if you think it’s not concerned with scales.Stamped Records wrote:Essentially, I'm just an advocate of the Circle of 5ths, and it's not really concerned with scales.
Overall I think you’re trying to compensate for gaps in your theory knowledge, but it’s not very successful based on some of the erroneous comments you’ve made above.
