The property of musical sound which differentiate between grave and shrill sound is called:
Correct answer: A. Pitch
- A. Pitch
- B. Intensity
- C. Beats
- D. Quality
Explanation
Pitch is the characteristic of sound by which we can distinguish between a shrill and a grave sound. The faster the vibrations, the frequency and pitch will be higher and sound becomes shriller whereas if sound is grave that means frequency and pitch will be lower.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
