Andrew Withington is musical director and conductor of the New Zealand Secondary Students Choir - a 60-strong chorus of teenagers who work with top vocal and acting coaches and perform across the country and around the world. He has just completed his PhD which involved creating his own system on how to teach choirs to sing more reliably and consistently in tune. He joins Kim to explain how his method works, and to play some of his favourite music. NZSSC will once again sing at the official ANZAC Day service at Pukeahu Park this year, and give two cathedral concerts in Wellington next week.
