To record the sounds and understand the occasion in which the instruments,called pututus,were played,researchers asked a shell musician to blow into the horn.They recorded the sound’s path through four small microphones placed inside the player’s mouth,the shell’s mouthpiece,the shell’s main body and at the shell’s large opening,or the bell.The team used signal-processing software to analyse the acoustic3 features of each trumpet.Following the sound’s path made it possible to reconstruct the ancient shell’s interior4 without damaging it.
