The 4 major music instructional methodologies are: Orff Schulwerk (Orff Approach), Kodaly, Suzuki and Dalcroze. If you know which approach the music center follows in general, you might have a better idea of their style. I attended an Orff Certification Workshop in SFO this summer, and I am still learning more about the other three methodologies. I have no intention to be a music teacher, I only wanted to learn more about it and hope to bring in more musical games in my classroom. The Orff course was one of the most amazing experience I had. It transformed me. It makes me feel that even I am not the most musical person, I could enjoy and create music and jam with some of the greatest musicians. I don't think there are any music center in HK that offer Orff music program, but some of them do incorporate the Orff Approach. For example, "Music Room" in Central uses the Taiwan Orff Music Program. They teach in Cantonese and most of the songs are in Mandarin. Please so share with us if you have more information about Orff in HK.
