Górecki, Henryk Mikoɫaj (1933–). Polish composer. The *Symphony of Sorrowful Songs* is constructed along the golden section. In the first movement, the soprano's entrance—the transition from the *lento* to the *sostenuto tranquillo ma cantabile*—occurs at precisely this moment, or $\frac{1}{\frac{1}{2}(\sqrt{5}+1)}\approx0.618034$ through the piece.
