I read in some threads that the resistance of this or a flute is higher (or lower) , etc.

Can someone explain what is exactly this resistance concept?

Thanks!

to me it is the thickness of the tube and the height of the embochure wall, Joe Butky could probably answer this better

Resistance is fairly subjective, however, it deals with the feeling a person gets when playing a certain instrument. You get feedback from an instrument. That feedback helps you, in part, to determine whether you like an instrument or not.

Some people feel they have to work harder to blow a particular instrument, or work harder to effect clean tonguing passages, etc. These are said to be more resistant and the subjective word "dark" is sometimes applied to the tonal characteristics.

There are many ways to add resistance to a flute. Any one variable can add resistance, but many variables added together result in the total amount of resistance felt by any given player. These variables include material,(particularly of the riser), riser height, shape and size of the embouchure hole, tubing thickness, and other minor factors....

Players are very different also, so what might feel resistant to one player might feel just right to another. Remember, there are reasons why there is resistance as I pointed out, but each player, depending on their own abilities, will feel these relative to their own playing abilities...

right you are Joe

Thanks Joe and Patrick.

How would you consider the EC cut of the Yamaha 600 series in terms of resistance?

As Joe and Patrick said, how resistant a flute seems depends on the player, but at least for me, I'd say the EC is moderately resistant. It certainly is not a platinum Powell (which is the most resistant headjoint I've played so far), but it does take a bit more to play it than, say, a student Gemmie.
