11.8 FL Z & nose air leak

To Jaume Rosset, Matthias Bertsch ,Bronwen Ackerman and Kees Hein Woldendorp.

Dear Jaume, good morning. End this week I've my new PC and will try to translate chapter 11.7.

But a quick reaction from me on your question Jaume, is this:

A good alternative for you perhaps is starting with Flatterzunge or flutter tonguing. As a point of depart for other exercises.

Thats: blow on brass of recorder (flute) with flutter tong technique.

You make with the tip of your tongue, using much air(support) the rolling r... from racing, but not in English but in Dutch phonetion... Ralletando...

The sound is 'rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr'.

And do that in different hights. The higher you play how more difficult is this. Then you'll see and feel that the back upper site of the tong will shut off the nose cavity. And you can feel that because when you do 'rrrrrrrrrrrrrrrrrrrrrrrr' technique there's an increasing pressure on the tympany. That's one of the practical proves that Flatterzunge helps to shut off the nose cavity.

In Darius Milhaud :La Creation du Monde the trumpets have to play FZ.

Perhaps can Matthias once :-) make a video for us where you can see the upper back of the tongue against the uvula region.

Kinds regards,

Hans Boschma


Test: 1.Without instrument
2.With instrument
Nose cavity as a sounding board of sound cabinet and as a sound rearranger ,a nasal sound reformer.
The nasal sound influences depends of the place of birth and way of education too ( Prof. De Tomatis).
Almost each letter of the alphabet needs a little bit of nasal sound. One less, the other more of that.
The N, M and NG (from Nominating, Mother an riNG cannot without nasal sound, and need the nose cavity for 100%.
Squeeze your nose and try to speak the N, M and NG, thats impossible and gives immediately press on the (ear) tympanic membranes.

a: around 5% difference light nasal - high more, low less
b: low more, high less

c: -
d: around 10% light nasal - high more, low less
e: 3 light nasal - high more, low less

f: -
g: around 3 light nasal - low more
h: -
i: around 3 light nasal - low more

k: -
l: -
m: 100% impossible to speak out with squeezed nose

o: -
p: 5% nb: during all lip- and or tongocclusions there occurs extra pressure on the tympanic membranes

q: -
r: -
s: - also during s and z hissing occlusions of the tongue against the incissors( front dents).
t: look after p.
u: 5%- 10% light nasal. Extreme low: much nasal sound interference
v: 3% very light nasal .Occlusion by lowerlip against upper incissors
w: 2% very light nasal .Occlusion
by lowerlip against upper incissors.
x: 1% Back of the tongue shuts off the pharynx

ij: -
z: 1% At first shut off by the vocal cords with voice.
All percentages are around, its not exactly to say. It depends also the influences of the education etc. place of birth.
