David Leigh is an opera singer, teacher, and composer. I had a great time interviewing David and talking about music theory, composition, and how his background led him to becoming an opera singer and teacher. His quantitative approach to music appeals to me—I was particularly fascinated to learn how he approaches the “low level” aspects of opera by using a spectrograph and spreadsheets.
When it came to talking about Quora, David expressed an interesting criticism I had heretofore only associated with Wikipedia. How do you deal with answers that seem great, but may not be credible or authoritative?
