How do boomwhackers work to produce sound and create music?

Boomwhackers are hollow, color-coded tubes made of plastic that produce different pitches when struck against a surface. The length of the tube determines the pitch it produces, with longer tubes creating lower pitches and shorter tubes creating higher pitches. By hitting the tubes in a specific order or rhythm, musicians can create melodies and harmonies, allowing them to make music with boomwhackers.
