## Title
Transverse whistle flute and method of playing

## Abstract

A musical instrument similar to the traditional flute but easier to play and master has been designed as an introductory flute. The whistle flute can also be used by those who have had difficulty with traditional flute embouchure and/or for recreation, education, music therapy, and stage performance. With greater range, easier handling, and simpler fingering, the whistle flute will augment or replace the recorder style flutes now used in elementary schools. In addition, the whistle flute's inner whistle design could be utilized as a training or transitional mouthpiece for any type of transverse flute.

FIELD OF THE INVENTION
This invention pertains generally to musical instruments and more particularly to transverse flute-type instruments of the woodwind family.
BACKGROUND OF THE FIELD
Transverse flutes and flute-type instruments, such as fifes and piccolos have been around for centuries. However, due to difficulties in sound production, these flutes present various problems for many people—including fingering and embouchure difficulties. The complex fingering on traditional flutes makes playing them problematic and even prohibitively so for the very young and other beginning players. A current alternative used in many elementary schools is the recorder (normally made of plastic with a built-in whistle mouthpiece), but recorders themselves present problems because they are blown vertically, presenting inferior handling to transverse instruments, and so do not afford a valuable introduction to traditional and orchestral flute-playing.
Various patented improvements have been made to recorder-type whistle flutes and other woodwind instruments in an effort to change the intonations and extend the ranges thereof. For instance, in U.S. Pat. No. 5,309,806 to Stavash, the device disclosed will change the intonation and pitch of a vertically-blown whistle flute by reducing the bore diameter. However, this device does not allow for any adjustment once inserted, and the instrument must still be blown vertically.
Likewise the devices disclosed in U.S. Pat. No. 4,515,060 to Ferron and U.S. Pat. No. 4,714,001 to Kergomard et al. reduce the bore sizes (at least in limited regions thereof) thereby changing the intonation of the instruments. However, these devices must be externally mounted on the instruments, and also the instruments must still be vertically blown.
SUMMARY OF THE INVENTION
The present invention solves the above-mentioned problems by providing a simple instrument that can be easily played and mastered by even young children and beginning players. The transverse whistle flute combines the blowing ease of the recorder as well as the well balanced handling of the traditional transverse flute. The transverse whistle flute also offers a greater usable range than a recorder, simpler fingering (in the six-hole pattern of the preferred embodiment), and elimination of the embouchure requirement of the traditional flute.
One embodiment of the invention comprises a cylindrical barrel—with a blowhole on the cylinder wall of one end and a series of finger holes towards the opposing end—and a whistle mechanism inserted into the barrel at the blowhole end (between the blowhole and the finger holes). With this design, a player, while holding the barrel of the whistle flute transversely to her body with the blowhole directly in front of her mouth, simply blows into the blowhole and fingers the finger holes, by alternately covering and uncovering them, according to the musical result desired. (The inventor has even composed a music book in tablature to assist the beginner.) The reflection of wind off the chamber walls before entering the narrow whistle passage is more similar to the effect made by a traditional embouchure than that of the end blown whistle.
Alternate embodiments may have the barrel reconfigured (elongated or narrowed) in order to afford a different key of music. The length of the barrel determines the pitch of the instrument, while the barrel diameter has the greatest effect on tone quality. Another embodiment comprises the whistle mechanism provided as an insert for converting traditional flutes to whistle flutes. The whistle mechanism may be used to build alternative mouthpieces or possibly as an insert to an existing mouthpiece.

DETAILED DESCRIPTION
FIG. 1 shows the transverse whistle flute 10 according to the preferred embodiment as it is to be held and fingered by a player. The preferred embodiment comprises a generally cylindrical barrel 12, having generally uniform wall thickness, with a blowhole 14, a series of finger holes 16, and a generally rectangular sound hole 18.
FIGS. 2A and 2B together show the orientation of all of the holes (14, 16, and 18), which holes are bored through the barrel wall, and their relationships to one another. According to FIG. 2A, one can see that in the preferred embodiment, each of the finger holes 16 is located on the imaginary top reference line 20, which parallels the longitudinal axis of the barrel, and proximate the second end 22, and the blowhole 14 is located approximately 30° measured circumferentially from the top line 20 and proximate the first end 26. Obviously in alternate embodiments, the finger holes may be offset circumferentially from the top line or may be located and spaced longitudinally according to a different pattern. Also, in the preferred embodiment, the transverse whistle flute 10 measures 14.25′′ in overall length. Although the length could obviously vary, such length is chosen in order to tune the transverse whistle flute to approximate the key of a traditional flute. In FIG. 2B, the sound hole 18, which is located approximately 180° circumferentially from the top reference line 20 and proximate the first end 26, measures 11.375′′ from the second open end 22. Once again, this arrangement is necessary only to approximate the key of a traditional flute but could vary according to different designs.
FIG. 3A shows a detail view of the whistle mechanism comprising plug and stopper. The generally round plug 24 is mounted within the barrel 12 adjacent the first open end 26 and fills the bore completely so as to seal the first barrel end. The plug must be located outward of the blowhole. The tapered stopper 28 is centered on the top line 20 such that the endplane 34 is oriented generally orthogonally to the longitudinal axis of the barrel and is mounted within the barrel 12 inwardly of the plug 24 creating a whistle chamber 30 defined by the barrel wall 32, the plug 24, the stopper 28, and the blowhole 14. The tapered stopper 28 stops the blown air from traveling freely down the barrel by obstructing the passageway, and instead forces the blown air through the small opening 38 of the whistle chamber, towards the sound hole 18, and over the wedge 36 thereof.
It is important in the preferred embodiment that the generally rectangular sound hole 18 be located as shown, i.e., coincidentally in line with the endplane 34 of the stopper 28 such that the generally 45° wedge 36 of the sound hole 18 is oriented as shown towards the first end 26 of the barrel 12. In alternate embodiments, of course, these arrangements can be modified per design. (The wedge can also be made at an angle of other than 45°; however, the wedge must be as close to 45° as possible for optimum sound quality.) The arrows of FIG. 3B indicate the path of blown air blown by the player (not shown) into the blowhole 14, through the whistle chamber 30 of the barrel 12, and over the wedge 36 of the sound hole 18 down the barrel 12 toward the finger holes 16 and the second open end 22.
FIG. 4 shows a whistle mechanism insert 40 that can be installed in any traditional transverse flute having a generally cylindrical open-ended barrel having a longitudinal axis, with blowhole and finger holes, in order to convert it to a whistle flute. The plug is installed at the proximate end outward of the blowhole to seal the barrel, and the tapered stopper is installed inward of the blowhole with its endplane coinciding with the sound hole to define the whistle chamber. (The sound hole will need to be punched into the barrel as traditional flutes do not have such sound holes.) The requirement of the embouchure is thereby eliminated, and air is blown directly into the blowhole. The blown air is then directed past the tapered stopper (through the small opening), over the wedge of the sound hole and down the barrel past the series of finger holes towards the distal end of the barrel. Due to the difficulty of modifying a flute barrel directly, the whistle mechanism may be installed in an alternative mouthpiece for a traditional flute. Also alternate embodiments may have the barrel reconfigured (elongated or narrowed) in order to afford a different key of music.
