What is claimed is: 1. A percussion musical instrument comprising: a beating surface and a shell, said beating surface being fastened to said shell; wherein said shell comprises at least two hollow bodies movable relative to each other along a shared axis of translation at least between a closed configuration in which a hollow body contains at least partially the other hollow body and an open configuration in which said two hollow bodies are substantially superposed; said musical instrument also comprising actuating means coupled inside the hollow bodies, to move said hollow bodies between the open configuration and the closed configuration; wherein said actuating means have a degree of rotational freedom relative to said hollow bodies to enable said hollow bodies to rotate independently of each other around said shared axis of translation. 2. Musical instrument as claimed in claim 1, wherein said hollow bodies are mutually coupled telescopically to obtain said closed and open configuration. 3. Musical instrument as claimed in claim 1, comprising a first end hollow body provided with a closed surface opposite to the beating surface and a second end hollow body provided with said beating surface, between said two end hollow bodies there being one or more central hollow bodies. 4. Musical instrument as claimed in claim 1, wherein an end hollow body comprises an annular undercut positioned at a first end, an additional end hollow body being telescopically inserted in the end hollow body and comprising an annular projection engageable in said undercut to define a position of maximum extension of the two end hollow bodies, said position of maximum extension coinciding with said open configuration. 5. Musical instrument as claimed in claim 1, comprising fastening means for retaining said hollow bodies in the closed configuration. 6. Musical instrument as claimed in claim 1, wherein said actuating means comprise a first array of thruster elements active between an end hollow body and a first abutment surface and a second array of thruster elements active between a second end hollow body and a second abutment surface; said first and second abutment surface facing each other and being in mutual contact. 7. Musical instrument as claimed in claim 6, wherein each array of thruster elements comprises a first rod-like element hinged to an end hollow body and a second rod-like element; said second rod-like element being also hinged on said abutment surface; elastic means acting between said first and said second rod-like element to thrust an abutment surface against the other abutment surface. 8. Musical instrument as claimed in claim 1, wherein said actuating means comprise a structure substantially shaped as a pantograph, rotatably fastened to two end hollow bodies. 9. Musical instrument as claimed in claim 1, wherein said actuating means comprise a first support element fastened to a first end hollow body, a second support element fastened to a second end hollow body and an elastic element interposed between the two support elements; said elastic element being freely rotatably along the shared axis of translation relative to the support elements. 10. Musical instrument as claimed in claim 1, wherein said actuating means comprise a plurality of telescopic cylinders fastened to two end hollow bodies; said telescopic cylinders being provided with elastic means to extend completely. 11. Musical instrument as claimed in claim 5, wherein said fastening means comprise a fastening element substantially “C” shaped, rotatably fastened in a central portion, to one of said hollow bodies and movable at least between a retaining position in which the fastening element is engaged with end hollow bodies and a position of release in which the fastening element is not engaged with end hollow bodies. 12. Musical instrument as claimed in claim 11, wherein said fastening element comprises a first and a second half-part slidably coupled to said first half-part; said first half-part and said second half-part comprising, at respective free ends, support feet destined to support the instrument when in use. 13. Musical instrument as claimed in claim 2, comprising a first end hollow body provided with a closed surface opposite to the beating surface and a second end hollow body provided with said beating surface, between said two end hollow bodies there being one or more central hollow bodies. 14. Musical instrument as claimed in claim 2, wherein an end hollow body comprises an annular undercut positioned at a first end, an additional end hollow body being telescopically inserted in the end hollow body and comprising an annular projection engageable in said undercut to define a position of maximum extension of the two end hollow bodies, said position of maximum extension coinciding with said open configuration. 15. A percussion musical instrument comprising: a beating surface and a shell, said beating surface being fastened to said shell; wherein said shell comprises at least two hollow bodies movable relative to each other along a shared axis of translation at least between a closed configuration in which a hollow body contains at least partially the other hollow body and an open configuration in which said two hollow bodies are substantially superposed; said musical instrument also comprising actuating means coupled inside the hollow bodies, to move said hollow bodies between the open configuration and the closed configuration; wherein said actuating means comprise a first array of thruster elements active between an end hollow body and a first abutment surface and a second array of thruster elements active between a second end hollow body and a second abutment surface; said first and second abutment surface facing each other and being in mutual contact. 16. A percussion musical instrument comprising: a beating surface and a shell, said beating surface being fastened to said shell; wherein said shell comprises at least two hollow bodies movable relative to each other along a shared axis of translation at least between a closed configuration in which a hollow body contains at least partially the other hollow body and an open configuration in which said two hollow bodies are substantially superposed; said musical instrument also comprising actuating means coupled with the hollow bodies, to move said hollow bodies between the open configuration and the closed configuration; wherein said actuating means comprise a plurality of telescopic cylinders fastened to two end hollow bodies; said telescopic cylinders being provided with elastic means to extend completely. 17. A percussion musical instrument comprising: a beating surface and a shell, said beating surface being fastened to said shell; wherein said shell comprises at least two hollow bodies movable relative to each other along a shared axis of translation at least between a closed configuration in which a hollow body contains at least partially the other hollow body and an open configuration in which said two hollow bodies are substantially superposed; said musical instrument also comprising actuating means coupled inside the hollow bodies, to move said hollow bodies between the open configuration and the closed configuration; wherein said percussion musical instrument comprising fastening means which comprise a fastening element substantially “C” shaped, rotatably fastened in a central portion, to one of said hollow bodies and movable at least between a retaining position, in which the fastening element is engaged with end hollow bodies for retaining said hollow bodies in the closed configuration, and a position of release, in which the fastening element is not engaged with end hollow bodies.
