The light and upbeat melody of Handel Messiah, great works by Mendelssohn and careful approach of Bach St. Matthew Passion became alive under his direction. Both technique and phrasing were learned through careful examination, on top of these, the spirit of the age – Zeitgeist – were always taught.
