Ah, the age-old question: Where the heck am I supposed to put this mute?!
This mute holder attachment for a sheet music stand is made of stainless steel, plywood, and EVA.
It was developed to help the musicians during a concert by holding the mute at an accessible angle that does not get in the way of their sheet music.
The product comes with a stainless steel piece with a wing nut and screw (also in stainless steel) that attaches it to a music stand. It can be adjusted for any thickness of music stand.
