I need to be more fluent with chords. Part of it is knowing a chord in any voicing, any inversion, etc. without having to put much thought into it. It's something along those lines.
Many of these chord progressions are just "manifestations" of the rules of basic theory. Obviously, following the circle of fifths is always acceptable. The viio going to iii is sounds okay because (theoretically in C) the B is a common tone between the chord, the D resolves up to E, the F resolves down to E, and the Ab resolves down to G. That said, you find the viio more common before the i chord. It is a common substitution for the V7. There is also the "deceptive cadence" where V goes to vi instead of I or V goes to VI instead of i. You said you were looking for more chromaticism. Why don't you insert a secondary dominant before one of the chords in your progressions? For example, I-IV-V7-I becomes I(7)-IV-II7(V7/V)-V7-I. For something real tricky, you could use the German sixth/Dominant 7 idea. A German sixth is a decoration on a five chord. In C major, it would be Ab-C-Eb-F#. The Ab resolves to G, the C stays put, the Eb becomes D, and the F# becomes G. However, look at the notes, and spell them like this: Ab-C-Eb-Gb. It is now the V7 of Db. You can go back and forth with these, turning Ge6 chords into Dom7s and the other way around. Also remember that dim7 can be respelled. Dim7 of C is B, D, F, Ab, and Dim7 of Eb is D, F, Ab, Cb. Same pitches, but a different resolution entirely. Another beauty in minor keys is the insertion of the Neapolitan, the bII in place of ii(half-dim). Proceeds directly to the V7. Just some ideas on creating mayhem in your music.
You could say a "one chord" "two chord" etc.Or... tonic for Isupertonic, iimediant, iiisubdominant, IVdominant, Vsubmediant, vileading tone chord, viioSo yes, "one, five, one" sounds normal to me.
My question is this, when the score has the left hand part written out but you don't want to play it for one reason or the other and you want to do your own thing with chords. How do you know which chord the composer intends for each measure? I have a general idea, however, not enough knowledge to get all of the chords worked out. The Lanz number that I am working on now is "Return to the Heart". Any help/direction would be appreciated. John
