Rock Core Xylophone


Use the beaters to hit the rock cores. Can you play a tune?

Each core is tuned to a pitch of a musical scale. We hear different notes because each rock core is differently sized, with the bigger sized cores creating larger wave lengths. Do the bigger cores produce a lower or higher note?

Follow this video and you can play a song using rocks! It works the exact same way as a xylophone, so just follow along to play.

True Rock Music

The rock core xylophone produces different notes because of the different lengths of rock. Larger pieces have a lower note, while smaller rocks have a higher note. This is because larger pieces allow larger wave lengths which result in lower notes. Shorter pieces result in more waves - a higher frequency and a higher note.
