Improvements in an expandable musical instrument stand where the components of the stand are constructed with tubular sections. The tubular section telescope with an extension mechanism placed between the tubular members to assist in adjusting the playing height of the musical instrument. The expandable construction allows the musical stand to be broken down into smaller sections to make it easier to transport and simple to erect. The expandable section is ideally used with the center tube with a three or four leg stand where the legs can be collapsible on the center tube or the legs can be constructed with the same or similar construction as the center tube where they can be stacked and clamped with a collar.

The invention claimed is: 1. A modular supporting stand comprising: a first center member supported by at least three legs where the position of the legs relative to the first center member is adjustable; a second center member that telescopes into said first center member at a first end; a securing means for securing a musical instrument on a second end of said second center member; a lift mechanism located inside said first center member and arranged to push said second center member at least partially out of said first center member; said lift mechanism is a compression spring or a gas filled strut, and a clamping apparatus secured to said first center member provided as a means for gripping said second center member to restrict extension of said second center member from said first center member at a user desirable position. 2. The modular supporting stand according to claim 1 wherein said first center member is fluted, indexed or keyed to limit rotational movement of said legs around said first center member. 3. The modular supporting stand according to claim 1 wherein said lift mechanism is replaceable to alter the lifting force and or lifting length. 4. The modular supporting stand according to claim 1 wherein said clamping apparatus uses an eccentric cam to clamp said second center member. 5. The modular supporting stand according to claim 1 wherein at least one of the at least three legs is independently adjustable for height. 6. A modular supporting stand comprising: a first center member supported by a base that exists from said first center member; a second center member that telescopes into said first center member at a first end; a securing means for securing a musical instrument on a second end of said second center member; a lift mechanism located inside said first center member and arranged to push said second center member at least partially out of said first center member; said lift mechanism is a compression spring or a gas filled strut, and a gripping mechanism arranged to provide a means for restricting extension of said second center member from said first center member at a user desirable position. 7. The modular supporting stand according to claim 6 wherein said first center member is fluted, indexed or keyed to limit rotational movement of said supporting base around said first center member. 8. The modular supporting stand according to claim 6 wherein said lift mechanism is replaceable to alter the lifting force and or lifting length. 9. The modular supporting stand according to claim 6 wherein said clamping apparatus uses an eccentric cam to clamp said second center member. 10. The modular supporting stand according to claim 6 that further includes an adjustment to alter said first center member off of a vertical orientation to effectively center said base under said musical instrument. 11. A modular supporting stand comprising: a first center member supported by a base that exists from said first center member; a second center member that telescopes into said first center member at a first end; a securing means for securing a musical instrument on a second end of said second center member; a lift mechanism located inside said second center member and arranged to push said second center member at least partially out of said first center member; said lift mechanism is a compression spring or a gas filled strut, and a gripping mechanism arranged to provide a means for restricting extension of said second center member from said first center member at a user desirable position. 12. The modular supporting stand according to claim 11 wherein said first center member is fluted, indexed or keyed to limit rotational movement of said supporting base around said first center member. 13. The modular supporting stand according to claim 11 wherein said lift mechanism is replaceable to alter the lifting force and or lifting length. 14. The modular supporting stand according to claim 11 wherein said clamping apparatus uses an eccentric cam to clamp said second center member. 15. The modular supporting stand according to claim 11 that further includes an adjustment to alter said first center member off of a vertical orientation to effectively center said base under said musical instrument.
