Are there going to be different levels, or will everyone be learning the same mantras/melodies?

There will not be separate classes for students on different levels. We are well aware that everyone will be on different levels. So, although there will be group sessions, teachers will do their best to give time and attention to individual students, to ensure that they are able to advance as much as they can from whatever level they are on. Thus all student will have possibilities to advance at their own pace in singing and playing instruments.
