The Waveline™ headjoint shortens the instrument in such a way as to relieve the spine from unnecessary strain. Without affecting the superb sound or intonation options, that is. This is especially important for practice where any form of strain is likely to cause fatigue.
Another specificity of the Extension Kit is the possibility to use just about any standard-sized headjoint. Before using a different headjoint, the latter should be adjusted by a specialist to ensure that the flute performs at its finest with the selected headjoint. Do not hesitate to ask your music dealer for details.
