The conch horn is likely the oldest labrophone or lip-reed #instrument. It's used around the world for communication, timekeeping, #Music and social and religious functions. Only medium to large shells can be played like a horn. Smaller ones can be whistles though. Being a tightly-coiled helix, the internal tube is around 3x the shell's length. The sound is resonant and powerful. Here's me playing mine. . #Ethnomusicology #WorldMusic (1/6)
