Hi Manny, your avatar shows Arnold Jacobs. I've read and watched a lot of stuff concerning him lately so my obvious question is : have you played with him or took lessons with him? Or can you share other things you learned from him. I became a big fan of his teaching after reading his book and watched the videos on his website. He and Bill Adam tought me a lot about trumpetplaying. Not that I changed anything. But I understand more what I'm doing when I'm playing the trumpet.
