nice project idea

9 out of 17 pieces are turned

i might turn the adjustable part of the support instead of using a
square piece

then top the round support with a square cap to allow for movement
of the music holder

looks like the swinging holder is prevented from falling back or
forward by hitting up against the square support

i might add an adjustment knob or lever for the swinging holder
just to allow for more degrees of freedom
