K: Amin T: 120 TS: 4/4 INST: Keys (electric/acoustic piano pad), Strings (legato ensemble / cello-violin), Percussion (very light brushes / soft electronic kit) Mood: Contemplative, cinematic, intimate, supportive for narration Structure: Verse (15 bars) → Chorus (15 bars) Summary: All core parameters are explicit in the description: A minor, 120 BPM, 4/4, 30 bars total = 60 seconds, and a two-section pop arrangement (Verse 15 bars → Chorus 15 bars). Primary instrumentation is Keys, Strings, and very light Percussion. Recommended stylistic implementation (high-level): - Keys: warm electric/acoustic piano or soft synth pad providing harmonic foundation and rhythmic comping in the verse, fuller voicings and brighter attack in the chorus; include small voicings, arpeggiated fills, dynamic CC11/CC74 automation and slight portamento/overlap for legato phrasing. - Strings: mid/high legato ensemble with counter-melodies and sustained pads in the verse, moving to more active, slightly higher-register lines in the chorus; use interval logic (harmonic thirds, fifths, sustained suspensions) rather than copied piano lines to preserve independent stem role. - Percussion: sparse, tasteful (brush/snare soft hits, light ride or shaker, soft kick) that grows in density into the chorus; include rhythmic micro-timing, velocity variation, and occasional fills to mark phrase ends and the verse→chorus transition. Arrangement and production notes to meet the brief: - Energy curve: verse is sparser and more intimate; chorus increases harmonic density, string motion, and percussion activity. Introduce phrase-ending fills every 5 bars and transition accents into bar 16. - Stem independence: each stem must contain distinct note material (different rhythms, ranges, and motifs) so any soloed stem clearly conveys its role. - Humanization & motion: apply micro-timing offsets, velocity dynamics, CC automation (CC7/CC10/CC11/CC74) and gradual curves for continuous evolution rather than abrupt jumps. - Section-aware dropouts: design stem-specific intentional rests and call/response gaps so no two stems share identical silence patterns. - DAW/MIDI considerations: use MIDI Format 1 with three separate tracks containing real note data and CC lanes for volume/pan/expression; ensure each track contains MIDI (or velocity‑0 placeholder notes where silence is intentional) through bar 30 so importing into any DAW yields three aligned 60‑second stems. Use case fit: - The resulting instrumental will be cinematic-pop, contemplative and neutral enough to support narration (YouTube shorts, proverbs, voiceover) while sounding like a finished commercial-quality instrumental without vocals.
