how to use the front f key ?

[mister_bronson]

does the front f key mean you don't have to use the side keys to obtain high F ? do i just have that key to hit the high f ? is the front f key used a lot for altissimo ?
another question : i just bought a T991 and apparently it can be adjusted but how ?
:?

To use the high F key on the front of the horn, try this:

Play high C with the octave key, then ADD the front F key with the finger you usually use for B. You can either rock the B finger onto the F key or lift it and place it only on the F key. A high F should come out. You do not need to add any of the palm or side keys. If you are on alto, you can get an F# by using this front F and adding the side Bb key with the right hand.

Adding to this...you can also get a high 'e' by using the same key and the same fingering as your high 'f'. Except, you need to press down your 4th finger (ring finger) as well.

What you'll find is a very difficult note to play. It does work, but what I've found, after many years of playing, is that the high 'e' using that alternative fingering, is still a tough note to get to speak properly.

The high E and F are MUCH easier on tenor than alto.

I use the front F key (or "Fork" fingerings) for E and F more than I use the palm key fingerings. And these fingerings also transition into the rest of the altissimo range quite easily.

There are F# and G fingerings that work well with the front F key.

For TENOR sax... to the front F fingering for high F, add side Bb and the RH1 (right index finger) and you have F#.

Adjust the front F key so that the pad of the F palm key only opens about 1/8" (about 3.5 mm). If the pad opens too much, E and F are easy, but F# and G become difficult. If open too little, F# and G are easy, but the E is difficult, and flat. There is a setting that will allow you to get all of these notes well.
