Re: Open G ok, High C sharp

Do be aware that the open G and high C utilise completely different toneholes, so check the F (thumb only) is in tune. Open G issues from the small tonehole beneath the throat A touchpiece whereas high C (and the lower register F) issues from the LH1 tonehole chimney.

Check their lower register F is in tune (thumb only) and if it too is sharp, then use some Blu-Tack or plasticine (modelling clay) to fill the LH1 tonehole chimney in enough to bring the pitch down. Fill it in from the top side (nearest the mouthpiece end) and form the filler in the shape of a crescent so the tonehole is still round instead of oval.

You can use the blunt end of a twist drill or a round smooth metal or plastic rod to shape the inside. And using Blu-Tack or similar putty that can be added to or removed easily, it can be adjusted easily too.

If you want something more permanent, then apply molten beeswax with a heated metal rod and then that can easily be adjusted by removing or adding more without any harm done to the clarinet.

If in doubt, seek the advice from a specialist clarinet repairer who understands clarinet acoustics and tuning.
