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.
