What does the term 'block voicing' refer to in jazz arrangements?

• A. A technique where families of instruments are treated as groups.
• B. A style of solo improvisation over a fixed rhythm.
• C. A method of drum scheduling in big bands.
• D. A device for muting brass sections.

Answer: (A)

Block voicing in jazz arrangements means organizing chords by treating instrument families as units and voicing the harmony as a single block across the sections. In practice, the horn sections—saxophones, trumpets, and trombones—are grouped to deliver the chord together, with each family responsible for certain notes to create a unified, dense sound. This yields a bold, punchy texture typical of big-band charts, because the ensemble moves as one harmonic block rather than each player running independent lines. It's not about solo improvisation over a fixed rhythm, drum scheduling, or muting devices—the focus is on how the chord tones are distributed across the sections to form a cohesive harmonic block.
