Lowboy, I am still experimenting but I do know that I can tongue much faster and my accents are much tighter. I seam to have more power when I need it but can choke the notes if to much. My notes seam more controlled. I can trill easier than with the straight pipe. Still a lot to learn since I had never played the Vibrandoneon with a French horn mouth piece. Same as a trumpet just much smaller.
