Other materials have been tried with varying degrees of success, such as the 1950s Grafton plastic alto saxophone. A few companies, such as Yanagisawa and Bauhaus Walstein, have made some saxophone models fromphosphor bronze because of its slightly different tonal qualities. For example, although their designs are identical apart from the metal used, the bronze Yanagisawa A992 saxophones are said to sound "darker" than the brass versions. Yanagisawa and other manufacturers, starting with the King Super 20 around 1950, have made saxophone necks, bells, or entire instruments from sterling silver. Keilwerth and Paul Mauriat have made saxes with a nickel silver body like that of a flute. The effect of material on sound is controversial among sax players, and little solid research has been published.
After completing the instrument, manufacturers usually apply a thin coating of clear or colored acrylic lacquer, or silverplate, over the bare brass. The lacquer or plating serves to protect the brass from oxidation, and maintains its shiny appearance. Several different types and colors of surface finish have been used over the years. It is also possible to plate the instrument with nickel or gold, and a number of gold-plated saxophones have been produced. Plating saxophones with gold is an expensive process because gold will not stick directly to brass. As a result, the brass is first coated with silver (which will stick to it) and then gold-plated on top.
Some argue that the type of lacquer or plating, or absence thereof, may enhance an instrument's tone quality. The possible effects of different finishes on tone is a hotly debated topic, not least because other variables may affect an instrument's tone colors e.g. mouthpiece design and physical characteristics of the player. In any case, what constitutes a pleasing tone is a matter of personal preference and tastes vary*************************************
so it's didi's 1st lesson.. imma so kepochi i asked permission from the kind teacher so that i can be there in the room to accompany didi (only for the 1st class... sigh)
i wish i could be there every class.. but i know i wouldnt wanna disturb them by doing thus didi christopher and i joined the 1st class as naive observer to have our curiosity feeded.
it's not easy to learn how to produce 'sound' by blowing.
i know didi is learning attentively and trying hard.
teacher teaching didi to blow the mouthpiece
