Ballad for Anna work in progress.

Verse composing – slow ballad.

Original Progression:

1. C-7 C-7 F7
2. C-13 C-13 F13
3. D7 A7 F7
4. C-13 F7 Bb7

Reharmonized Progression:

1. Cm7 F7 Bbmaj7
   • The original C-7 can serve as the ii (Cm7), F7 as the V, resolving into Bbmaj7 as the I in the key of Bb major for a traditional ii-V-I cadence.
2. Gm7 C7 Fmaj7
   • Substituting the C-13 with Gm7 (vi chord in Bb major) leading to C7 can resolve to Fmaj7 for another ii-V-I feel but in the key of F.
3. D7b5 G7b9 Cm7 F9
   • Use D7b5 and G7b9 to create a chromatic approach to Cm7, setting up another ii-V with F9 resolving back towards a tonic feel of Bb major.
4. Cm7/Eb Ab7 Bbmaj7
   • Start with Cm7 as a minor ii, use Ab7 as a tritone substitution for D7 leading smoothly into the I chord (Bbmaj7).

Explanation:

• The progression now centers more around the key of Bb major with carefully placed ii-V-I sequences to create smooth transitions.
• In the second set of chords, using Gm7 and C7, provides a temporary modulation to F major, offering an interesting shift back to Bb major.
• D7b5 and G7b9 introduce altered chords, creating tension that resolves through Cm7 and F9.
• The use of Ab7 as a tritone substitution adds a rich harmonic surprise before settling on the Bbmaj7 tonic.

I strive for richer harmonic palette while emphasizing the ii-V-I progressions in Bb major
