What is a Trumpet Bell Cover? 

The concept of trumpet bell covers is a relatively new concept because it only appeared after the strong outbreak of the covid-19 epidemic. Understandably, the trumpet bell covers act as a mask to prevent or reduce the large amount of saliva that accumulates from the bell flowing out. By sealing the bell mouth, this protects other players from corona infection.

What is the purpose of trumpet bell covers? 

When you blow the trumpet, a large amount of saliva accumulates in your trumpet. During a complex pandemic, it is difficult to prevent this from spreading further as COVID spreads rapidly through respiratory droplets. Accordingly, it is recommended that trumpet players use bell covers to help reduce the transmission of aerosol droplets while playing (by the National Federation of High School Societies (NFHS)). 

In addition, one particular study found that a trumpet bell cover can reduce, on average, nearly 80% of respiratory droplets in the air. Therefore, trumpet bell covers are used specifically to help prevent the spread of aerosols during trumpet play.

What is the best material for a trumpet bell cover?

Ideally, trumpet bell covers should be made from stretchy fabric (88% polyester + 12% spandex). Depending on the recommended size according to your instrument, sizes range from 3.75 – 5″ (95 – 127mm) to create a barrier for droplets and germs.

Do trumpet bell covers affect sound and timbre?


As previously reported, trumpet bell covers can affect sound and timbre due to the added pressure difference of the bell cap. Some trumpeters mention that trumpet bell covers can also impair their judgment and pronunciation. Professional players easily find the sound a bit muffled because there is a physical layer covering the bell and not much air escapes from the trumpet. With ensembles such as marching bands, this is a problem for them, they will need to use more steam to increase the volume as desired. However, inexperienced audiences can hardly discern this difference and still enjoy good and captivating music.
