Oscar’s Quiet Drum

Oscar wants a soft drum sound for his garden song. He taps the little drum, then wonders where the sound comes from. Dad sits beside him. “Let us look, listen and feel gently,” he says.

Oscar gives the drum a gentle tap with one finger. A sound reaches their ears. The drum skin moves after the tap, but the movement is hard to see.

They rest their fingertips lightly on the drum skin after a tap. Oscar feels a tiny trembling. Dad calls this a vibration: a quick movement back and forth. The vibrating drum skin helps make the sound.

Oscar lays his hand gently across the skin. The trembling stops, and the sound fades. The skin is still. He lifts his hand and taps again. The drum makes another sound. “Stopping the movement changed what I heard,” he notices.

They compare gentle taps with slightly firmer taps, keeping them comfortable for their ears. The firmer tap sounds louder in this test. Dad reminds Oscar that louder and higher are different ideas. Today they are comparing loudness.

Oscar draws a drum and a hand. He tells Dad what he felt and heard. His picture cannot make a sound, but it can help him remember the action that made the drum skin move.

A bird begins singing nearby. Oscar puts the drum down so they can listen. Making sounds is one choice; leaving a quiet moment is another. He does not need to drum loudly to enjoy their garden song.

When they put the drum away, Oscar taps its skin once more. “A tiny movement makes a sound,” he says. “My hand can stop it too.” His question has led to something he can try and describe.
