My son's piano teacher also teaches voice. My sense is that, as with the learning of any other instrument, progress is a mixture of talent and discipline. Since singing with a capital S requires a lot of odd physical coordination, it strikes me that progress comes more incrementally than with other instruments. Some of the recitals I've been to have been pretty rough.

I would think that a good singing teacher is one who 1) has credentials or background and 2) has a conversation with the prospective students about goals and does not lead anyone to think they can live out their American Idol or Glee dreams.
