## Background
BACKGROUND
This disclosure relates generally to a musical instrument, and more particularly to a musical instrument that uses a liquid to assist in generating various musical notes or tones.
Musical instruments, such as percussion instruments, wind instruments, and string instruments, are well known. In particular, musical instruments operate by producing a vibration that can be perceived by a human ear as an audible sound and interpreted as a musical note or composition. In order to produce a musical note, the musical instrument must be able to produce a vibration and sometimes amplify the vibration. All musical instruments have a sound generating mechanism that is capable of producing musical notes. For example, a drum head may be struck to produce a vibration or a string may be plucked to produce a vibration. Although such instruments are known, learning how to play and master such instruments can be a time consuming and frustrating endeavor. Further, some musical instruments are very large and are difficult to move from location to location. This may reduce the ability of a musician to practice the instrument. Other musical instruments are very expensive and may not be rented due to their expense. The expense of the instrument may hinder a musician from learning to play the instrument. In view of this, there is always a need to develop a musical instrument that is easy to learn how to play, inexpensive, and of a compact design.
The present disclosure is designed to obviate and overcome many of the disadvantages and shortcomings experienced with prior musical instruments. Moreover, the present disclosure is related to a musical instrument that can be easily manipulated or played to produce various musical notes. The musical instrument of the present disclosure is also simple to learn how to play due to the size of the musical instrument and the nature of the musical instrument.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, wherein like numbers refer to like items, number 10 identifies a preferred embodiment of a musical instrument constructed according to the present disclosure. Referring now to FIGS. 1 and 2, the musical instrument 10 is shown to comprise a first inner tubular member or section 12 that is adapted to be inserted into a second outer tubular member 14. The first tubular member 12 has an inlet end 16, an outlet end 18, an interior surface 20, and an exterior surface 22. The second tubular member 14 has an inlet end 24 and a closed end or portion 26. The second tubular member 14 also has an interior surface 28 and an exterior surface 30. The second tubular member 14 has the closed end 26 to stop movement of the first tubular member 12 when inserted therein. The closed end 26 is also for allowing the second tubular member 14 to hold or store a liquid (not shown), such as water, when the first tubular member 12 is inserted therein. When a liquid is placed in the second tubular member 14 and the first tubular member 12 is inserted therein, the musical instrument 10 may be operated or played. In particular, the first tubular member 12 may be moved relative to the second tubular member 14 and a player may blow air by or into the inlet end 16 to produce a musical note. By moving the first tubular member 12 relative to the second tubular member 14 various other musical notes may be generated or produced. The first tubular member 12 is also centered in the second tubular member 14. A liquid inserted into the second tubular member 14 acts as a lubricant to facilitate movement of the first tubular member 12 relative to the second tubular member 14. The exterior surface 22 of the first tubular member 12 is adapted to frictionally engage the interior surface 28 of the second tubular member 14.
The first tubular member 12 has a length and the second tubular member 14 has a length. Typically, the length of the first tubular member 12 is longer or greater than the length of the second tubular member 14. This allows the first tubular member 12 to extend out of the inlet end 24 of the second tubular member 14. This also provides for easy grasping or handling of the first tubular member 12 relative to the second tubular member 14. It is also possible and contemplated that the length of the first tubular member 12 is smaller or less than the length of the second tubular member 14.
FIG. 3 illustrates an inlet end view of the musical instrument 10. The musical instrument 10 is shown to comprise the first tubular member 12 inserted into the second tubular member 14. The first tubular member 12 has the inlet end 16, the interior surface 20, and the exterior surface 22. The second tubular member 14 has the inlet end 24, the interior surface 28, and the exterior surface 30. The exterior surface 22 may be frictionally engaged with the interior surface 28. Positioned between the exterior surface 22 of the first tubular member 12 and the interior surface 28 of the second tubular member 14 is a liquid 32, such as water. The liquid 32 assists in moving the first tubular member 12 relative to the second tubular member 14. The liquid 32 also provides to center the first tubular member 12 within the second tubular member 14. The first tubular member 12 has a diameter and the second tubular member 14 has a diameter. As can be appreciated, the diameter of the first tubular member 12 is less than the diameter of the second tubular member 14. This allows the first tubular member 12 to fit within the second tubular member 14. The diameters of the first tubular member 12 and the second tubular member 14 are circular in shape or cross-section. The first tubular member 12 has a thickness 34 and the second tubular member 14 has a thickness 36. The thicknesses 34 and 36 may be the same or different.
Referring now to FIG. 4, a partial perspective view of the closed end or closed end portion 26 of the second tubular member 14 is shown. The closed end 26 has a flat end 40. The flat end 40 may be a cap portion or may be formed as part of the second tubular member 14. The second tubular member 14 also has the exterior surface 30.
FIG. 5 depicts another partial perspective view of the closed end 26 of the second tubular member 14. The closed end 26 is shown having a concave end 42. In this particular configuration, less liquid may be held or stored within the second tubular member 14. A player may find that having less liquid within the second tubular member 14 may enhance musical notes that are produced by the musical instrument 10.
With reference now to FIG. 6, another partial perspective view of the closed end 26 of the second tubular member 14 is illustrated. The closed end 26 is depicted having a convex or hemispherical end 44. With this configuration it is possible to have more liquid stored in the second tubular member 14.
FIG. 7 illustrates another embodiment of a second tubular member 50. The second tubular member 50 has an inlet end 52, an exterior surface 54, an interior surface 56, and centering ribs or nubs 58, 60, 62, and 64 along the interior surface 56. The centering nubs 58, 60, 62, and 64 are used for centering the first tubular member 12 when the first tubular member 12 is inserted into the second tubular member 50. The exterior surface 22 of the first tubular member 12 will be in contact with the centering nubs 58, 60, 62, and 64. Liquid (not shown) will be able to fill in the spaces or pockets 66, 68, 70, and 72 formed between the nubs 58, 60, 62, and 64 and the exterior surface 22 of the first tubular member 12. Although four centering nubs 58, 60, 62, and 64 are shown, it is also possible to have more nubs or less nubs. Further the nubs 58, 60, 62, and 64 may extend the entire length of the second tubular member 50 or only extend a portion of the length of the second tubular member 50.
With reference to FIG. 8, another embodiment 100 of the musical instrument is shown. The musical instrument 100 comprises a first tubular member 102 having an inlet end 104, an outlet end 106, an interior surface 108, an exterior surface 110, and a first length 112. The musical instrument 100 also comprises a second tubular member 114 having an inlet end 116, an outlet end 118, an interior surface 120, an exterior surface 122, and a second length 124. The first length 112 may be greater than the second length 124. The musical instrument 100 further comprises a third tubular member 126 having an inlet end 128 and a closed end 130. The third tubular member 126 is sized and shaped or adapted for receiving the first tubular member 102 or the second tubular member 114 for moving the first tubular member 102 or the second tubular member 114 relative to the third tubular member 126. The third tubular member 126 also has an interior surface 132 and an exterior surface 134. The closed end 130 of the third tubular member 126 is used to stop or restrict movement of either the first tubular member 102 or the second tubular member 114. As can be appreciated, the first tubular member 102 having the first length 112 may be capable of playing different sounding musical notes or tones than the second tubular member 114 having the second length 124. In this manner, a player of the musical instrument 100 may change out the tubular members 102 and 114 depending upon what notes or tones are to be played or produced. The third tubular member 126 also has a length 136. The first length 112 may be larger than the length 136 and the second length 124 may be smaller than the length 136.
The closed end 130 allows the third tubular member 126 to hold or store a liquid, such as water, when the first tubular member 102 or the second tubular member 114 is inserted therein. When a liquid is placed in the third tubular member 126 and the first tubular member 102 or the second tubular member 114 is inserted therein, the musical instrument 100 may be operated or played. In particular, the first tubular member 102 or the second tubular member 114 may be moved relative to the third tubular member 126 by sliding the first tubular member 102 or the second tubular member 114 up and down and by a player blowing air by or into the inlet end 104 or 116 to produce a musical note. By moving the first tubular member 102 or the second tubular member 114 relative to the third tubular member 126 various other musical notes may be generated or produced. The first tubular member 102 or the second tubular member 114 are also centered within the third tubular member 126. A liquid inserted into the third tubular member 126 functions as a lubricant to facilitate movement of the first tubular member 102 or the second tubular member 114 relative to the third tubular member 126. The exterior surface 110 of the first tubular member 102 and the second tubular member 114 are adapted to frictionally engage the interior surface 132 of the third tubular member 126.
The length 112 of the first tubular member 102 may be longer or greater than the length 136 of the third tubular member 126. This allows the first tubular member 102 to extend out of the inlet end 126 of the third tubular member 126. By way of example only, the length 112 may be a half inch greater than the length 136. Also, the length 124 of the second tubular member 114 may be shorter or less than the length 136 of the third tubular member 126. It is also possible that the length 124 may be equal to the length 136. The first tubular member 102 has a diameter and the third tubular member 126 has a diameter. As can be appreciated, the diameter of the first tubular member 102 is less than the diameter of the third tubular member 126. This allows the first tubular member 102 to fit within the third tubular member 126. The second tubular member 114 also has a diameter that is less than the diameter of the third tubular member 126. The diameters of the first tubular member 102, the second tubular member 114, and the third tubular member 126 are shown to be circular in shape or cross-section. Although not shown, it is also possible that the third tubular member 126 may be constructed having the centering nubs 58, 60, 62, and 64. Further, the closed end 130 may take on any form such as a concave end, a convex end, or a flat end, as has been previously described with reference to the closed end 26.
Preferably, the musical instruments 10 and 100 will be constructed of a relatively lightweight material so that it can be easily handled and played. By way of example only, the musical instrument 10 and 100 may be constructed of a tubing such as PVC (polyvinyl chloride) tubing, wood, metal, polymer clay, plastic, glass, carbon fiber, or ceramic. The first tubular member 12 and the second tubular member 14 and the first tubular member 102, the second tubular member 114, and the third tubular member 126 may be straight to facilitate a smooth motion when moving the first tubular member 12 relative to the second tubular member 14 or the first tubular member 102 or the second tubular member 114 relative to the third tubular member 126. Although the tubular members 12, 14, 102, 114, and 126 have been depicted having a circular cross-section, it is also possible that the cross-sections may take on other shapes. Again, by way of example only, an oval cross-section, an egg shaped cross-section, or a rectangular cross-section may be used. It is also contemplated that the tubular members 12, 14, 102, 114, and 126 may be clear, colored, or have a pattern or a logo printed thereon or incorporated therein.
