I've watched a video about conducting entitled "Making Music Alive". I really admire the conductor Lloyd Faustch who is being featured in the video. Presented are the 3 methods that are used in choral teaching which he called 3 keystones: Warm-up, Breathing and Diction. I am thinking if there can be additional methods used aside from the three. Please shed light on this.
I was also struck about his statement that the choir members tend to imitate the voice of the conductor. It is rather dangerous to do it because they don't actually understand how the conductor uses his voice in terms of technique. I have made my own comments about it and would be glad to hear some comments from you too.Thank you.

Personally I would not suggest to try and get the singers to copy/imitate the conductors voice. As a singer my self I like when the conductors makes us (choristers) read the poetry and then from the text create our own idea of what voice sounds we want as a choir. For example you don't want to imitate a conductor who is a trained operatic singer when you are conducting a piece by say Morten Lauridsen or Eric Whitacre. You might want that style if you are singing the classic Ave Maria? perhaps. other advice would be to make the singers love the song, if they (we) don't like it we wont sing it as good as we can or could. Hope this helps?
