Prompt

Turn the following ideas into a sheet-music ready MIDI file with complete, complex, professional melodic lines and human-sounding composition. Do not actually create a MIDI file, just write a Python script that create the MIDI file using your writing. Here are the ideas: **Saxophone Quartet Piece Ideas/Notes** Central Theme: three movements, inspired by VGM, modern pop, and Broadway The biggest challenge is going to be to capture the lushness of the themes with only four voices. Measures are indicated with vertical bars (\| Chord Symbol \|). If there are two chords in a measure, each chord's value is two beats. If there are four chords in a measure each chord's value is one beat. **Movement I: Encounter\! At the Neon Crossroads** This movement will be in a fast video game music style. Chord progression and main ideas are as follows: Tempo: 160 bpm \| Time Signature: 4/4 Key: Concert D Minor/F Major Length: \~64 bars **Intro** Arrange with rapid arpeggios in the Alto and Tenor to simulate 8-bit chiptune textures, while Bari lays down a punchy bassline and Soprano plays a frantic motif. 1-4: \| Dm \| Bbmaj7 \| Gm7 \| A7sus4 A7 \| 5-8: \| Dm \| Bbmaj7 \| Gm7 \| Em7b5 \| A7 B°7 A7/C\# Dm \| **Section A: Toby Fox Inspired** Think "Bonetrousle" or "Spider Dance." Heavy staccato on beats 2 and 4 in the inner voices. Bars 9-12: \| Dm \| Dm/C \| Bbmaj7 \| A7 \| Bars 13-16: \| Gm7 \| C7 \| Fmaj7 \| Bbmaj7 A7 Ab7 G7 \| Bars 17-20: \| Dm \| Dm/C \| Bbmaj7 \| B°7 \| Bars 21-24: \| Dm/A \| Bb7 \| Gm7 \| A7 Bb B°7 C7 \| **Section B: "Royal Road" Progression (More Pokemon Inspired)** Legato, soaring melody in the Soprano and Alto in octaves or harmony. Bars 25-28: \| Bbmaj7 \| C7 \| Am7 \| Dm7 \| Bars 29-32: \| Gm7 \| C7 \| Fmaj7 \| Cm7 F7 F7/A Bb \| Bars 33-36: \| Bbmaj7 \| B°7 \| F/C \| D7 \| Bars 37-40: \| Gm7 \| Bbm6 \| F/C D7 \| Gm7 F/A Bbm6 C7 \| **Section C: Boss Phase** Unstable, tense, building energy. Bari Sax plays relentless eighth-note pedal tones on A. Bars 41-44: \| Bbmaj7/A \| Gm7/A \| Dm/A \| A7 \| Bars 45-46: \| Bbmaj7 \| Gm7 \| Bars 47–48 : \| Dm E°7 Dm/F Gm7 \| Ab°7 Dm/A Bb7 A7 \| **Section A': Final Climax** Bars 49-52: \| Dm \| C \| Bbmaj7 \| A7 \| Bars 53-56: \| Gm7 \| A7 \| Dm C \| Bbmaj7 \| Bars 57-60: \| Gm7 \| Em7b5 \| Dm/A Bb7 \| Gm7 A7 Bb C7 \| Bars 61-64 (The Finale): \| Bb \| C \| Dm \| Bb C A7/C\# Dm \| (Hard staccato hit on beat 4 of bar 64\) **Movement II: Resting in the Rain** This movement is in the style of a slow modern pop ballad (Finneas/Billie Eilish, Olivia Rodrigo, Adele, Tate McRae, etc.). Tempo: 68 bpm (Rubato Feel) \| Time Signature: 4/4 Key: Concert Eb Major Length: \~48 bars **Intro: Lonely** Start without the Baritone Sax. Let Tenor play the bass notes for a fragile, airy sound. Bars 1-4: \| Eb(add9) \| Gm7 \| Abmaj7 \| Abm6 \| *(Voicing Eb(add9): Eb–G–Bb–F)* **Verse 1: Intimate Storytelling** Solo Alto Sax carries the melody; the other three play warm, sustained pad-like chords. Heavy use of slash chords creates a smooth, descending pop bassline in the Bari.

Subtone in the Tenor and Bari. Bars 41–44: \| Eb(add9) \| G7(\#5) \| Cm7 \| Abm(maj7) \| (Abm(maj7) \= Ab–Cb–Eb–G, deeply cinematic) Bars 45–48: \| Eb/Bb \| Bb7sus4 \| Abmaj7 \| Eb(add9) \| (Hold final chord, let the 9th hang in the air) **Movement III: The Curtain Rises\!** This movement is a medium-fast fusion of Pop, VGM, and powerful Broadway (Pasek & Paul, Wicked, and Final Fantasy). Tempo: 120 bpm (anthemic and driving) \| Time Signature: 4/4 Key: Concert G Minor → Bb Major → C Major (\~72 Bars Total) **Intro: Broadway Vamp** Think "Waving Through a Window" or "Defying Gravity." Bari and Tenor play a driving, syncopated eighth-note pulse; Alto and Soprano enter with rhythmic stabs.

The harmonic rhythm speeds up to build hype. Bars 25–28: \| Ebmaj7 \| Bb/D \| Cm7 \| Gm \| Bars 29–30: \| Abmaj7 \| Eb/G \| (Abmaj7 is the heroic bVII borrowed chord) Bars 31–32 (2-Bar Quarter-Note Broadway Climb): \| Cm7 Dm7 Ebmaj7 E°7 \| F7sus4 F7 Eb/G F/A \| **Chorus 1: The Showstopper Belt** Pure Broadway/Pop euphoria in Bb Major.
