What is the triangle of auscultation?

The triangle of auscultation is a small area of the back where three muscles (trapezius, latissimus dorsi, and rhomboideus major) converge. This area is near the scapula and becomes enlarged when a person leans forward with arms folded across the chest. When a physician places a stethoscope on the triangle of auscultation, the sounds of the respiratory organs can be clearly heard.
