This invention relates to new designs of tubular body flutes both to facilitate more natural and more consistent placement and orientation of the flute player's hands and to enhance the flexibility of the player's lips so as to more perfectly play the flute by greatly increasing the stability of the flute in the player's hands by firmly connecting the flute to the player's finger (and / or thumb) by provision of a finger connecting part through which the flute player's left index finger is inserted, as like wearing a ring. It firmly fixes the flute to the player's left index finger (and / or thumb) so that the flute is stabilized without pressure on the player's mouth. Thus, it enhances the flexibility of the player's lips to more perfectly form the airstream sounding the flute while also more exactly and repeatedly locating the player's fingers on the flute by preventing inadvertent rotation of the flute. This is especially beneficial for the player's lower lip, which, under extant art, is forcibly pinned against the lower teeth and gums so as to stabilize the flute. This benefit is achieved by completely stabilizing the flute in the player's hands by firmly connecting the flute to the player's finger (and / or thumb) with a finger connecting means incorporating an opening in the invention through which the flute player's left index finger (and / or thumb) is inserted, as like wearing a ring.In the preferred embodiment the finger connecting means is a ring-like structure built onto the flute and for economy this additional device is hereafter referred to as a ring. The use of a ring provides a firm connection between the player's fingers and the flute permitting the left index finger and right thumb to completely stabilize the instrument with no pressure on the player's lips whatsoever, while completely preventing inadvertent rotation of the flute.A very substantial benefit of the instant invention over extant art is that it allows the flute to be safely played by growing children without disrupting the proper development of their gums and teeth. Many parents permit their children to start their music education only with a piano or a violin because wind instruments have a tendency to put severe stress and strain on the mouth, teeth and gums, which can distort their development. Because the instant invention permits, even encourages, the best use of the flute without strong, or even any, pressure on the teeth and gums, a flute so equipped can be used even by young children without orthodontial concerns.

The instant invention relates to new attachments for the round tubular body of flutes. It firmly, but easily and removably, affixes the flute to the player's left index finger (and / or thumb) so that the flute is stabilized without pressure on the player's lower lip. Thus, it enhances the flexibility of the player's lips so as to more perfectly play the flute while also more exactly and repeatedly locating the player's fingers on the flute, while preventing inadvertent rotation of the flute. This is especially beneficial for the player's lower lip, which, under extant art, is forcibly pinned against the lower teeth and gums so as to stabilize the flute. This benefit is achieved by completely stabilizing the flute in the player's hands by firmly connecting the flute to the player's finger (and / or thumb) with a finger retainer incorporating an opening through which the flute player's left index finger (and / or thumb) is inserted, like wearing a ring.In the preferred embodiment, the finger retainer is a ring-like structure built into the flute-finger connector and for economy this system is hereafter referred to as a ring. The use of a ring provides a firm connection between the player's fingers, the flute-finger connector and the flute permitting the left index finger and right thumb to completely stabilize the instrument with no pressure on the player's lips whatsoever, while completely preventing inadvertent rotation of the flute.One benefit of the instant invention over extant art is its flexibility with respect to the types of flutes it may be connected to. In one embodiment, attachment to the flute body is by an extraneous, extant, devices, such as cable ties, hook and loop, etc., which are adjustable and flexible so as to permit attachment of the device to tubular body flutes of widely varying cross-sectional dimensions, such as alto, bass, piccolo and treble flutes, as well as the more common C flute. Thus, a player could invest substantially in a device made of high-quality material, such gold with precious stones, assured of their ability to easily move it from flute to flute and between any number of different types of flutes.A second benefit of the instant invention over extant art is that a player can use it without altering their hand position from how they would play the flute without the device. The absence of any pad between the ring and the body of the flute means that the player's left hand index finger rests directly on the body of the flute, exactly the same as it would rest on the flute absent the invention. Thus, this invention requires no adjustment to the player's style of playing whatsoever, except that it enhances the stability of the flute and allows it to be played with any amount of pressure on the player's lower lip, including none.Another very substantial benefit of the instant invention over extant art is that it allows the flute to be safely played by growing children without fear of distorting the proper development of their gums and teeth. Many parents permit their children to start their music education only with a piano or a stringed-instrument because wind instruments have a tendency to put severe stress and strain on the mouth, teeth and gums, which can distort their development. Because the instant invention permits, even encourages, use of the flute without strong, or even any, pressure on the teeth and gums, a flute so equipped can be used even by young children without orthodontia concerns.
