Bb3 Trumpet Oval-shaped / Fish-shaped (Trompette Si bémol 3 en forme ovale, forme de poisson)
thingiverse
The bell design of my project, OpenBrass (http://www.openbrass.org), is based on the paper "Trumpet with near-perfect harmonicity: Design and acoustic results." I made adjustments such as modifying thickness and sleeves, inspired by other acoustics studies. Check out the YouTube demos for a live demonstration (https://www.youtube.com/watch?v=NvPm9aHb9AQ & https://www.youtube.com/watch?v=_SHB_CY29JQ).
