Getting through your transition from chest voice to head voice and back again takes a forward placement. Forward vowels are like ‘oo,’ like in ‘too,’ ‘ih’ like in ‘if,’ and an ‘e’ sound with an ‘oo’ mouth shape. Forward consonants are ‘f’ and ‘v’ and the plosives ‘p’ and ‘b.’ It it easier to make the register change when your placement is more forward in the upper chest range to match the forward placement for your lower head voice range. The yodle sound comes from a more back of the throat placement on the lower note jumping to a higher note in a forward placement. Think of forward placement in your nose or just behind it. If you sound too nasally, back it up a bit, opening your mouth more.
If your voice comes out like Marlena Deitrich or you have a covered, swallowed sound and want a brighter one, place it more forward!
