can anyone tell me what is the point in spending money when how many pieces for flute have low b in them?

Usually, it has a Low B and a high C facilitator.
Understandable question and some don`t bother with them. As a matter of fact some may say that it damages the tone quality on the flute. In High School level playing, 98% of the time students don`t even use the low b or the higher range at all.

On the + side, you can play low b`s and it makes high Cs and higher come out more easily.

I use mine all the time especially in the French pieces.

I actually had to play part of a piece with several low b`s at my audition for a flute spot in my college`s higher band. There were other pieces of music that we had to play too, of course, without low b, but my friend and fellow flutist was so freaked out about blowing her audition due to her c-foot that she asked to borrow my footjoint for her audition. So if you plan to play in college it may be worth it to spend the extra dollars.

If you play in a flute choir you will encounter low B`s in most music.

I now play on a low c again and can usually play a substitute note if I encounter a low b, whenever I give lectures to young people I often ask for a show of hands of those who have a bfoot, then I ask for a show of hands for those who have actually played a low b and very few raise their hand.
I prefer a c foot on my flute because of its age and scale

in solo music a b foot is only really required for some french pieces or more likely avant garde modern music si it depends on the kinda of music you play. HOpe this helps

The B foot joint helps the low C to play in tune better than without it.

who told you that Emmy? doesn`t make any sense

Maybe she in confusing the low C to the fourth octave C?

Re: "On the + side, you can play low b`s and it makes high Cs and higher come out more easily."

What high C are we talking about here? The flute`s normal range is from middle C to the C three octave`s above. I`ve written the Db above THIS high C as well--because the flautist I`d engaged to try what I wrote as I went could negotiate it seemingly effortlessly.

About the low B: As soon as composers begin to assume they will get it when they ask for it they will ask for it. As long as composers assume they will not get it they will not ask for it and will do perfectly fine without it. Collectively, the matter is in your hands.

Re: "Maybe she in confusing the low C to the fourth octave C?"

The normal range of the flute is only three octaves.

Re: "I now play on a low c again and can usually play a substitute note if I encounter a low b."

If the composer finds out he`ll shoot you, and the court will rule the act a justifiable homicide. On the other hand, if you shoot the composer for writing a low B in the first place, the court will rule this act a justifiable homicide also. The quicker draw wins.

"The normal range of the flute is only three octaves"

Oh my gosh! Sorry, you are correct, really, I did know that. No more champane for me tonight! Lol! I would love to see someone try to hit a fourth octave C though!

alls I know is that when playing very contemporary pieces, I need to join a support group afterwards to recover
