Hoarse sound - what are the reasons?

Hoarse sound

How can a hoarse sound be avoided?

Hoarse sound - occurs when water-drops get trapped in the wind-channel.

Remedies:

  • pre-warm the mouthpiece to body temperature (prevents cold condensation)
  • Anticondens Sprinkle the air exit opening (1) with Anticondens, especially in the corners. With the palm of your hand, hold closed the opening of the underneath of the headpiece (2) and forcefully blow back the liquid, starting from the labium opening through the wind-channel (3). Enclose the labium opening with your lips to do this.

A 'clogging' is usually normal until the block edge is completely wet and the water can run off at the front. If the wood surface in the wind- channel is rough or overlaid with dirt particles, neither pre-warming or Anticondens will help (characteristic: the hoarseness persists). The only solution is to send it in for cleaning. A block which is too swollen increases the clogging tendency.
