techniques

There seems to be a debate between two major breathing techniques in the
production of sound. The first one consists of pushing the air by
tightening the abdominal muscles and keeping them pushed out. The second
technique in discussion consists of pushing the air through more air, not
by tightening the muscles. Supposedly the diaphragm is to push in and up.
On the first technique the diaphragm is supposed to remain pushed out and
down. It seems to be quite contradictory for arriving to similar results.
Does anybody have any thought about this matter? What are the advantages
and disadvantages of this techniques? Are there any more breathing
techniques? It would be great if information related to sound production
such as quality (dolce vs. agressive), projection, flexibilty in the tone
and other qualities can be provided.

Thanks, Gorgias

here is from a post I sent 4-12-99

The diaphragm is Voluntary during inspiration, and in-voluntary during
expiration. When the diaphragm contracts, the dome descends and the base of
the thorax expands. It also increases the vertical diameter of each half of
the thorax. Its contraction elevates the lower ribs (except the last). When
the dome descends, the chest expands, air is drawn into the lungs and the
abdominal viscera, related to its under surface, are displaced. When the
diaphragm relaxes, it recoils into its higher domed position in a purely
passive manner. This occurs during expiration and when expiration is deep,
largely due to the increased activity of the abdominal muscles, the
diaphragm is passively forced upwards.
The whole breathing topic surrounding the function of the intercostal
muscles has been a source of controversy throughout medical history. The
mechanical action of the individual intercostal muscles has not yet been
fully established. There are different theory's on that. some theories
attribute certain opposing respiratory actions to the two individual groups
of muscles, while other theories give the reverse actions to the same
individual groups. Still others argue that both views are wrong and that
the muscles work together in different movements of the chest during
breathing. Some anatomical works state that while both intercostals are
elevators of the ribs, they also form strong elastic supports which prevent
the intercostal spaces being drawn in or bulged out during respiration. One
of the most popular theories is that the external intercostals and the
intercartilaginous internal intercostals raise the ribs and are therefore
regarded as muscles of inspiration, while the interosseous internal
intercostal muscles depress the ribs and are therefore muscles of expiration.
In only one sentence:
Increase support as you get softer.....
