One or many teachers

Some days ago a borderline heated exchange of opinions took place: should a beginning tango student take lessons from just one or from many teachers. My opinion:

It is my deep belief that for a person who wants to learn how to dance tango socially (not for a show or just with a single partner) and is new to tango, the best solution is to attend a substantial seminar for beginners lead by a reputable organization and taught by a single teacher or a group of teachers subscribing to the same philosophy of dancing and teaching and following the same program.

Substantial seminar means to me a seminar over perhaps 30 to 40 hours that focuses on understanding the structure of the dance, understanding and sufficiently commanding the basic technical skills (walk, turn, balance, communication), understanding and appreciating the music, and understanding and participating in and contributing to the culture of a milonga.

When a tango student acquires those fundamental skills, studying with other teachers can be useful and even recommended in order to discover new ideas and perhaps even altogether new approach to learning and dancing tango. But, before the basic set of skills is acquired, one is not yet qualified to study with a different teacher and to be able to pick and choose what works for them or not and why.
