Check the listing for details. On-Stage Serenity Series Wave Bead Drum - 16 inches. Condition: New. Listed at 86.95 USD. Let the Rhythms Flow The soothing sounds of the sea, rainfall, and beyond await within this wave bead drum from On-Stage’s Serenity series. A fun and relaxing experience for musicians and non-musicians alike, as well as for therapeutic use and meditation, this drum delivers a range of cresting sonics, from gentle laps to crashing curls. Its unique sound comes from a durable 16-inch beechwood frame capped by a mellow-toned natural goatskin head and a brighter, clear PET head, filled with a healthy mingling of steel and plastic beads that can easily be added to or subtracted from to achieve different sounds. However, Sweetwater percussionists enjoy how this instrument can create a wide variety of non-oceanic effects, depending on how you hold and strike it.
