The saxophone is pretty much now a 3 octave instrument. Altissimo itself is not difficult to achieve but I am having trouble getting those high notes to blend (in a classical sense) and sound like lower notes below the palm keys. The Ibert has some crazy altissimo in it and none of it is relatively hard to play but getting it to sound warm is a different story. For those of you who major(ed) in saxophone or just happened to know a lot in this subject, how could I make my altissimo sound better or how can I gain more control of my altissimo tone wise? Claude Delangle has a recording of the ibert and his control over the altissimo register is astounding and I know this is just every saxophone player but I want my altissimo to be able to sound as controlled as his.
