Jeff Suzda has been a great help in sharing his altissimo techniques with the rest of us. His approach is generic to the saxophone and specific to the baritone. If you are unfamiliar with his altissmo then you haven’t heard his albums. His tone in the upper range is full and direct. It is the type of tone that reflects the years of study he has invested in it. Enjoy the video he posted on YouTube, it’s a great way to approach those difficult first altissimo notes.
