Rather than something that looks like this.
The Cherry Blossom Cloud by Charles Juhasz-Alvarado has been displayed outside the Mead Center for American Theater in Washington DC as part of this years National Cherry Blossom Festival. Drumsticks were available nearby for passers-by to activate the xylophone by playing a melody or creating their own musical work.
If you can’t remember what a xylophone sounds like you can play a virtual xylophone by clicking here or here. Or you could listen to Gone Daddy Gone by Violent Femmes. Gone Daddy Gone, which features 2 xylophone solos, is from the album also titled Violent Femmes released 29 years ago this month.
I couldn’t find any other songs that I was familiar with that featured a xylophone. The unusual percussion on Under My Thumb by the Rolling Stones is the marimba.
