Very few soprano saxophones have a facility to play a high G! This is one of the few. Whilst the note is not often required, it is there for the professional who requires it.
An interesting little observation on the Yanagisawa soprano sax is the long rod operating the speaker key from the G spatula. No it is not unlacquered, it is in fact made of the very strong and expensive metal - nickel silver. There is no silver in nickel silver. It is an alloy of brass using a percentage of nickel to make it strong.
This strong rod is just another evidence of the perfection of the Yanagisawa engineering approach in designing for the requirements of the players. Without this strength the saxophone would not speak as well as it does across the range. You will see this when you compare the Yanagisawa Elite Soprano Saxophone with other brands.
