Create an 8-bar modern-pop loop in E major.

Chord Progression (1 bar each, repeat twice)

| Amaj7 | E | B | C#m7 |

Tempo & Meter

  • 100 BPM, 4/4, straight feel.

Tracks

  1. Electric Bass
    • Root-focused 8th-note pulse.
    • In bar 4 (C#m7) add passing tone B→C# on the “&” of beat 2.

  2. Electric Piano (Comping)
    • Mid register (E3–E5), 3- to 4-note voicings held for a full bar.
    • Voicings:
    – Amaj7 = A C# E G#
    – E = E G# B
    – B = B D# F#
    – C#m7 = C# E G# B

  3. Synth Lead – Simple Lyrical Melody
    • Soft pluck or gentle saw patch, range E4–B4.
    • Compose a 4-bar singable melody of mainly quarter notes, starting on beat 1 of bar 1:
    - Bars 1–4: use only chord tones (root, 3rd, 5th, 6th) to keep it consonant.
    - Bars 5–8: repeat the melody with a slight ending variation (e.g., resolve to C# on bar 8).
    • Keep intervals mostly stepwise or small thirds; avoid leaps > a 4th.
    • Velocity 75–85, humanize timing ±10 ms.

Dynamics & Humanization

  • Bass 70–85, piano 60–75, lead 75–85.
  • Randomize note starts/ends ±10 ms; keep downbeats tight.

Output Requirements

  • Exactly 8 bars, 3 tracks, 4/4, 100 BPM.
