Prompt

Create a full-length, complex, score-ready MIDI file based on the following notes. The piece will be for a full traditional wind ensemble with percussion, piano, drums, electric bass, and electric guitar. There should be a clear melody that is not randomly generated, with repeating motifs. The melody should not ever just be in one instrument. Since this is a hollywood piece, have some impressive-sounding French horn parts like they would in a Hollywood score. The percussion part should keep time but also not be just boring subdivisions. Try not to double parts. Each instrument should have a complex, moving, or meaningful line. There are no strings. If high strings are mentioned in the notes, use flutes or clarinets instead. If low strings are mentioned, assign them to bass clarinet/bassoon/tenor sax. It should sound massive and epic where appropriate. Do not return an actual MIDI file, because that is impossible for you to do. Return a Python script that will create the final MIDI file. Notes: To achieve a blend of Golden Age Hollywood (lush, sweeping strings), 1940s–80s Gospel (warm, soulful, churchy), and the Blues (gritty, emotional), the ultimate musical touchstone here is something akin to Quincy Jones’s score for *The Color Purple*, or Sam Cooke’s "A Change is Gonna Come." We will set this in the key of **G Major**. It is a warm, resonant key for orchestral strings and very natural for gospel piano and blues guitar. **Tempo:** 64 BPM (Slow, deliberate, and heavy) **Time Signature:** 4/4 (Played with a gentle 12/8 Gospel triplet feel beneath it) **Notation Note:** Chords separated by slashes (e.g., **G / Am7 / G/B / C**) indicate **moving quarter-note chords**—one chord per beat—used to drive energy into the next measure. --- ### **INTRO: The Golden Age Overture (0:00 – 0:45)** *Instrumentation: Lush Hollywood strings and harp. No drums. It should feel like the opening credits of a 1950s epic, slowly melting into a warm gospel piano.* | **Cmaj7** | **Cm6** | **Gmaj7/D** | **E7(b9)** | | **Am9** | **D13** | **G / C/G / G / D7sus4** | **G** (Piano enters alone) | *(Note: The **Cm6** is the quintessential "old Hollywood" heartache chord, while the quarter-note movement in bar 7 brings us down to Earth, straight into the church pews).* ### **VERSE 1: The Testimony (0:45 – 1:30)** *Instrumentation: Intimate. Just a warm Fender Rhodes or Grand Piano, a soft Hammond B3 organ pad, and a solo voice or solo cello/horn. Very 1940s Thomas Dorsey gospel.* | **G** | **G7/B** | **C6** | **C#dim7** | | **G/D** | **Em7** | **A9** | **D7 / C/E / D/F# / D7** | | **G** | **G7** | **C9** *(Blues inflection)* | **Cm6** | | **G/D** | **E7(#9)** | **Am7 / G/B / C / C#dim7** | **D7sus4** **D7** | ### **CHORUS 1: The Horizon Opens (1:30 – 2:15)** *Instrumentation: A deep bass guitar and light gospel brush-drums enter. Low strings swell. The melody climbs higher.* | **G** | **G / Am7 / G/B / G7/B** | **C** | **B7(#9)** | | **Em7** | **A13** | **Am7** | **D7 / E7 / F#dim7 / D7/F#** | | **G** | **G7/B** | **C** | **C#dim7** | | **G/D** | **Bm7 E7** | **Am7** **D9** | **G / C/G / G / D7** | ### **VERSE 2: The Struggle (2:15 – 3:00)** *Instrumentation: Keep the groove steady. Add a bluesy, weeping electric guitar (think B.B. King) answering the main melody in the spaces.* *(Repeat Verse 1 Chords, but replace the last two bars with this massive quarter-note Gospel walk-up to launch into the next section):* | **Am7 / Bm7 / Cmaj7 / C#dim7** | **G/D / Em7 / D/F# / B7/D#** | ### **BRIDGE: The Storm & The Blues (3:00 – 3:50)** *Instrumentation: This is the 1970s/80s Gospel-Blues peak (think Andraé Crouch). Full orchestra and rhythm section. Heavy timpani rolls, brass swells, and crashing cymbals. It starts dark and builds relentlessly.* | **Em7** | **Bm7** | **C7** *(Gritty Blues)* | **B7(#9)** | | **Em7** | **G7/D** | **A9/C#** | **C7** **B7** | | **Am7** | **G/B** | **Cm6** | **C#dim7** | | **G/D** *(Hold & Build)* | **G/D** *(Louder)* | **D7 / Em7 / D/F# / G** | **Am7 / G/B / C / D7(b9)** | ### **CHORUS 2: The Soaring Climax (3:50 – 4:40)** *Instrumentation: Maximum volume. Soaring Hollywood French horns play counter-melodies against a full 1980s Gospel choir vibe. Every cadence uses quarter-notes to keep the energy cresting.* | **G** | **G7 / Am7 / G/B / G7/B** | **C** | **Cm6 / D7 / Ebdim7 / B7/D#** | | **Em7** | **A13** | **Dm9** *(Cinematic shift)* | **G7 / Am7 / G/B / G7** | | **Cmaj9** | **C#dim7** | **G/D / F#dim7 / Em7 / Dm7** | **C#dim7** **Cm6** | | **G/D** | **E7(#9)** | **Am7 / G/B / C / A7/C#** | **D7sus4** *(Huge pause)* | ### **OUTRO: The Resolution & "Amen" (4:40 – 5:45)** *Instrumentation: The rhythm section drops out completely. We are left with the sweeping Hollywood strings and the gospel piano. The tempo gradually slows down (ritardando).* | **G** | **G7/B** | **C** | **C#dim7** | | **G/D** | **Em7** | **Am7 / G/B / C / E7** | **Am7** **D7(b9)** | | **Em7** *(Surprise deceptive cadence)* | **A9** | **Cmaj7** | **Cm6** *(Long hold, strings swell)* | | **G/D** | **Am7/D** | **C/G** *(The "Amen")* | **G** *(Fade to silence)* | --- ### **Why this works (and stays simple):** 1. **The "C - C#dim7 - G/D" movement:** This happens several times. It is the most famous progression in Golden Era Gospel. It instantly gives you that soulful, churchy lift without requiring complex jazz theory. 2. **The "C - Cm6 - G" movement:** This is the "Over the Rainbow" / Classic Hollywood cadence. By putting it right next to the gospel chords, you seamlessly blend the cinema with the church. 3. **The Quarter-Note Walk-Ups:** By using simple scale walk-ups (like **Am7 - G/B - C**) on every beat at the ends of phrases, the music feels like it is physically lifting off the ground.
