What is ab flat on trumpet?
B flat is played by pressing down the first valve (the one closest to the mouthpiece). Buzz as low a note as possible while holding down the first valve. It is highly unlikely you will be too low, as low B flat is the lowest note playable on a trumpet with only the first valve. Play low C.
