In an ideal world, the saxophone would be responsive at the
softest pianissimo levels and would not break up at at
fortissimo; intonation problems could be easily adjusted; and the
timbre of each note would be even. Of course, we know that this
is not the case, but through cryogenic treatment, many of these deficiencies can be considerable improved.
The problem starts with the manufacturing process. As tone
holes are drawn from the body, as the bell is shaped over a
mandrel, and as posts are soldered, the natural lattice of atoms
in brass is disrupted, causing internal friction. The natural
structure of brass is such that the atoms line up in perfect rows
that are densely stacked atop one another. During the
manufacturing process, this alignment is disturbed as the atoms
are dislocated. The metals ability to resonate is diminished so
that only the strongest harmonics of each pitch are transmitted.
Cryogenic treatment removes residual and compressive stresses
in the saxophone by allowing the brass to return to its optimum
structure. The instrument is gradually cooled (over a period of
24 hours) to approximately -400 degrees F, and then allowed to
return to normal temperature gradually (another 24 hours). The
saxophone is NOT immersed in liquid nitrogen (this is a dry
process) and no damage will occour to lacquered or plated
finishes. There is occasionally some loosening of pads and corks.
Cryogenically treated saxophones are more responsive
dynamically, have a more even scale, and have less
"dead" notes. I have had my personal instruments
treated, as well as those of a number of my customers. You will
be amazed by the results. Please Email for prices, delivery time,
