Bellow-operated instruments, like the harmonium, use hand-pumped bellows to push air through reeds, while wind instruments, like the flute, require direct breath control to create sound.

Class 6 Arts Grade 6 chapter 7 musical instruments solutions
Bellow-operated instruments, such as the harmonium, use manually pumped air to vibrate reeds and produce sound. Players control pitch by pressing keys while maintaining airflow with bellows. In contrast, wind instruments like the flute or shehnai require musicians to blow air directly through or across an opening to create vibrations. While wind instruments depend on breath control for sound modulation, bellow-operated instruments provide a consistent airflow, making them easier to sustain notes and play for extended durations.
