1. The Sound (Instrument Selection) Best Choice: "Sub Bass"

K: Amin T: 120 TS: 4/4 INST: Piano, INST:SynthBass, INST:Drums Mood: Introspective, melancholic, spacious, cinematic ballad Structure: Verse-Chorus-Bridge The musical style is a modern electronic ballad, characterized by a spacious "half-time" feel despite its moderate 120 BPM tempo. The foundation is built upon a prominent piano melody and its underlying chord progression. The rhythmic core is simple yet powerful, with a kick drum anchoring beat 1 of each measure. The defining element is the deep, sustained SynthBass (specifically a Sub or Sine wave), which plays the root note of each chord for the entire bar. This creates a "glued," continuous low-end foundation that adds emotional weight and a chest-rattling physical presence. The overall effect is cinematic, introspective, and designed to support a soulful or emotional lead melody.
