Which adventitious lung sound is high-pitched and musical?

High-pitched, musical sounds come from airflow that is rapidly moving through narrowed airways, causing a whistling, continuous noise. This describes a wheeze, which is typically heard during expiration and can be heard during inspiration in more severe obstruction. Wheezes reflect airway narrowing from bronchospasm, edema, or obstruction, as seen in conditions like asthma or COPD. Crackles are discontinuous popping sounds from airways popping open, often due to fluid in the alveoli or atelectasis. Rhonchi are lower-pitched, snoring or gurgling sounds from secretions in larger airways. Pleural friction rub is a harsh, grating noise from inflamed pleural surfaces, heard with respiration and not musical.
