[quote=loveofskins;40483906]I think you can sing 'But the tigers come at night' in both head and chest voice, you dont have to drop your voice right down to chest voice, in fact its better if you dont because it is harder to get out of chest voice once you drop right into it. When you go into head voice you have to close your 'thin folds' as oppose to your 'thick folds' which you shut when you are singing chest voice (vocal folds) so if you over-blow in your 'thin folds' i.e. head voice then you can blow into falsetto by mistake and then your voice gets very airy and pitchy.
I suppose it all depends who trained you as to how you explain it - and what style of singing - I was not only trained for musical theatre but also opera. Different teachers conjour up different visualisations but it is your brain that interprets this to get the tone.
Using your folds description using a chest voice too high is a common thing with less experienced singers and can lead to nodules and damaged vocal chords.
Further to voices resonating ( vibrating ) in chest or head is where you position thr voice in the mouth to the front which makes it crisp and precise and further back which increases tone at the cost of diction and clarity. Catherine Jenkins really annoys me because she seems to almost swallow her vowels to gain a very rich tone
It is all a voyage of discovery - your voice truly is an instrument as Charlotte Church says and experimenting and exploring what a voice can do is wonderful - although we do need coaches to guide us and make sure we do not get into bad habits, teach techniques to produce the sounds we want and to hear the voice externally.
Have you noticed on these reality shows, how often an untrained performer seems to go backwards from their starting points as they correct mistakes and learn technique before they make a breakthrough
