The COVID-19 pandemic has caused adverse effects on instrumental music teaching and concerts, including those involving wind instruments. Many schools now use bell covers and air filters during rehearsals and performances to help prevent aerosol transmission of disease. This study sought to examine if the use of these bell covers and filters might have an effect on mean instrument pitch. A sample of pitches in the low, middle, and high tessitura of each wind instrument were collected in three groups: no treatment, bell cover only, and bell cover with air filter. The data was then entered into the analytical software package "R." T-tests and Analysis of Variance were run on the data to compare the three groups. Additional comparisons of mean pitch deviation were also made as to instrument family (brass/woodwind) and note (low tessitura to high). The analysis showed that when using both bell cover and filter, there is a small degree of sharpness when compared to performing with no treatment.
