Class 6 NCERT Arts Chapter 7 Musical Instruments solutions
Bellow-operated instruments generate sound by pushing air through reeds or pipes. The harmonium is a popular example, where pressing the bellows forces air through metal reeds, producing sustained notes. Another example is the accordion, which expands and contracts its bellows to control airflow, creating melody and harmony. These instruments allow dynamic expression, making them widely used in classical and folk music. Bellows enable musicians to control volume, sustain notes and create smooth transitions between pitches.
