Description

  The present invention relates to a flute, and more particularly, to a flute including a straight pipe body and a blower pipe. The straight tube has a plurality of keys for changing the pitch. The air outlet tube has an air outlet plate and is connected to a linear tube body to which a key is attached.

  In the conventional flute, the air outlet tube is directly connected to a tube body to which a key is attached. Since the pitch of the flute must be limited or set to an accurate frequency band, it is necessary to ensure a sufficient distance between the mouthpiece plate and the key that moves the flute during playing. An adult flute player can adjust the arm to move optimally to accommodate the distance between the mouthpiece plate and the key, so that the flute can be played comfortably. Such a flute player does not need to make hand movements that cause poor finger movement or fatigue. Also, adult flute players do not need to crawl their heads in an unnatural position that causes fatigue.

However, for flute players who do not have an adult body shape, especially children, the gap between the mouthpiece plate and the key that is moved to change the pitch when playing the flute is too large, which causes various problems. Stretching the arm prevents the player from skillfully moving his finger, making it easier for the player to feel tension, stiff shoulders and back stiffness. As a result, practicing or learning the flute can damage the bone.

Proposals have been made to bend the outlet tube 180 degrees in order to shorten the distance between the outlet plate and the key for changing the pitch. However, in such a proposal, the mouthpiece plate is shifted from the geometric axis of the pipe body to which the key is attached, and the flute player cannot hold the flute in a stable state and learns the flute tone. I can't. Also, the special fingering method learned to play a bent flute is not useful when playing a conventional flute having a straight outlet tube. In addition, it is difficult for a flute player familiar with a bent flute to adapt to a conventional flute fingering method having a straight outlet tube.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a flute capable of reducing or avoiding the above problems.
