Conductor Kevin Purcell writes on his personal website:
There are schools of conducting thought that have evolved over the years. Some of the more prominent of these (in no specific order) are the Saito Method (apologies for the lack of diacritic), the Malko and Scherchen inspired techniques and the Russian ‘Musin’ school.
The Saito Method has its own website, but I've found it difficult to find information on the other techniques mentioned here.
What is the distinction between these methods? How do they differ?
