Which statement correctly differentiates pitch and quality of murmurs?

• A. Pitch can be high, medium, or low; quality can be blowing, harsh, rumbling, or musical
• B. Pitch describes loudness; quality describes duration
• C. Pitch is the same as duration; quality describes frequency
• D. Pitch and quality are unrelated concepts

Answer: (A)

Pitch and quality are two distinct auditory attributes of a murmur. Pitch refers to the frequency of the sound—how high, medium, or low it sounds. Quality describes the character or timbre of the murmur—the way the turbulence is heard, described as blowing, harsh, rumbling, or musical. This distinction matters because a murmur can be, for example, high-pitched yet harsh, or low-pitched yet musical, depending on the lesion and flow pattern. Loudness (amplitude) and duration (how long the murmur lasts within systole or diastole) are separate aspects and do not define pitch or quality. Quality specifically captures the qualitative character of the sound, while pitch captures its frequency. Clinically, you assess pitch with the stethoscope’s diaphragm for higher frequencies and the bell for lower frequencies, while noting the quality to infer the nature of the turbulent flow.
