Just a single sound

I am the WOOSH of the trees On a steady midnight breeze Hear the THUD of my heartbeat The CRACK of bones in my feet I am very alive I WHIMPER, BAWL, and SNIFF in tears RATTLING beneath the weight of years The SNORE and SHUSH of a tired mind I'm the CLINK of treasure you find I'm real through it all We're the RUSH of waves from the tides The RUMBLE of stone as earth divides A world of HUMMING and DRUMMING As the strings keep STRUMMING I'm just a single sound
