Which extended techniques are harmful to flutes?

During composer workshops, I am sometimes pleased to hear the question: “What are some techniques we should definitely not use because they may harm your instrument?”

So I will keep a running list here.

  • Slamming your hands onto the keywork. A snap of the finger for a key click is one thing (and not all flutists like to do this, including myself), but once I was actually asked to raise my arm above my head and bring my hand down full force on the keywork. Repeatedly. For some reason, I had trouble convincing this particular composer that this might actually break or bend the posts and rods holding the keys in place.
  • Immersing part of the flute in water. If water, even a tiny drop, gets onto the key pads, the pad can swell up and not seal properly (and it may need to be replaced). The same can happen when pads are exposed to excess moisture, which is why I do not like to play out of doors, but that can’t be helped sometimes.
  • Putting your mouth directly on wooden lip plates. This is why I get out my plastic piccolo if I have to do a tongue ram or any percussive effect that requires me to close the embouchure hole with my mouth. Salivation is the first stage of digestion, and I don’t want the result of those chemical processes on finely carved wood.
  • (Not an extended technique, but please bear in mind.) Extreme temperatures. With metal flutes, key pads and the mechanism might go out of adjustment. With wooden instruments, it can be fatal! Some insurance companies will not even pay out if damage occurred while the instrument was below or above certain temperatures.

I am sure I have forgotten something!

  1. These tips are extremely useful and I like the charts with the question boxes and answers. I couldn’t find a full list of all the common extended techniques, what they are and how to use them.
