The objective, really for the singer is to create a situation where when he starts to sing he's no longer worried about technique, he's done all that, and he can give the whole of his or her attention to the song itself she can give her or he can give his whole attention to the sheer act of enjoying the song."
spot on, jim, master technique,so that one is confident with singing breathing etc , then think about interpretation of the song.
musicans practise their instrument the voice is just another instrument, one of the most sensible things Ewan advocated, was vocal warm up exercises.
but here is something else diet, the condition of the voice can be improved by avoiding certain drinks/ foods, i found it interesting that mick jagger at glastonbury, sprayed his vocal chords with manuka honey and herbs, and limited his talking to an hour, I would be interested to know what herbs he used to keep his voice in good condition, it certainly wouldnt have been smoking marijuana., that is very bad for the voice
