Instrument prompt review challenge
Bring the instrument system together: recognize the family, choose the source, decide what it contributes, describe how it behaves, and place it where the arrangement needs it.
What this challenge checks
Choose the instrument cue whose job matches the target
- Recognize common string, woodwind, brass, percussion, keyboard, and electronic sources.
- Separate rhythm, bass, harmony, melody, accent, and transition roles.
- Choose an acoustic or electronic palette deliberately.
- Create contrast through texture and section-specific entrances.
Review the system
Build the direction in four decisions
Move from source to arrangement
Family and sourcestrings → cello; keyboard → piano
Sound paletteacoustic, electric, electronic, hybrid
Texture and actionfingerpicked, muted, sustained, bowed
Arrangement rolepulse, foundation, harmony, melody
Section placementverse core, pre-chorus entrance, chorus lift
Testing decisionchange the layer tied to the symptom
Keep the plan coherent
A small set of layers can still create movement

Before you begin
Use the audible-job rule
