On this I would say yes, although some of the forms it takes I don't agree with. The best example I can give is the approach of the Boston Byzantine Choir and Fr. Apostolos Hill. My question would be is whether or not this westernized approach should appropriately be called Byzantine Music. There is a certain feeling among large groups that Byzantine music can and should be "Americanized" and I fell the only "Americanization" it needs is to be given is to be performed in English with possibly original melodies to fit English. I think the trills, scales, and general performance style should remain the same. I do feel that in spreading this that aspects of the Karas method would be very helpful for spreading Byzantine Music in America. Mainly the learning of ornamentation and performance in pieces. As there are, up to this point, no masters in the art of Byzantine Music in English to imitate, that trying to learn proper ornamentation from listening to Greek masters then applying it to English, while maybe the most ideal way, isn't the most practical way, and aspects of Karas' method could help fill in the gaps in terms of training a psaltis more quickly. I am no expert on his method though, so I would pick and choose the aspects from his method I liked that I was exposed to in Greece. Others who have been exposed and know his full method would have more to say on this idea (the importation of his method to English) than I do.
