Katherine Chu and Juliet Petrus, both alumnae of San Francisco Opera’s Merola/Adler young artists’ program, have written “the first book to introduce Mandarin as a language for singing, with a detailed explanation for the creation of sounds and a system for learning them. … Singing in Mandarin combines a brief study of linguistics, notes about the history of China and Taiwan, the development and significance of Pinyin …, a wealth of information about Mandarin pronunciation, and scores with multilingual text of Chinese [art] songs.” – San Francisco Classical Voice
