Query: Music Teacher

I have owned a Petersen for about 15 years now. It has held up remarkably well, and is much more sturdy than any wire stand. It is lightweight, packs in to a notebook sized, self-contained unit, and has wings which pull out from both sides to accommodate full sized orchestral scores. As previously mentioned, it is not good for tall players, but can be angled back nicely.Many of my students and friends have made purchases after seeing mine.
