Wind instrument the bell, and the bell's function in this case is to improve the consistency in tone between these notes and the others. Playing some wind instruments, in particular those involving high breath pressure resistance, produce increases in intraocular pressure, which has been linked to glaucoma as a potential health risk. One 2011 study focused on brass and woodwind instruments observed "temporary and sometimes dramatic elevations and fluctuations in IOP". Another study found that the magnitude of increase in intraocular pressure correlates with the intraoral resistance associated with the instrument, and linked intermittent elevation of intraocular pressure from playing high-resistance wind
