Expand the range of the alto saxophone, please
Hello! I have the following request: expand the range of the alto saxophone from E flat 6 to G sharp 6 by sound (For a saxophone recording from С of the fourth octave to F of the fourth octave). I ask this because the modern saxophone range already reaches notes higher C of the fourth octave, and in some pieces I cannot write these notes (higher C of the fourth octave) and this is inconvenient. For some reason, there is no such limit on soprano saxophone.
