At first glance the sections for two simultaneous instruments look
harder than they actually are. As a saxophonist myself, I have a
feeling the embouchure challenge is harder than the fingering.
In the 1st
system that uses two instruments, the alto stays on open C# so both
hands are available for soprano fingering.
down the page to the 2nd system that involves two instruments, both
instruments can play LH only by using the palm-key fingerings for D and
D# in the soprano.
On the next
system, bottom of p6 of the solo part, the alto uses regular LH
fingering; the soprano uses the D# palm fingering, and for the low F#,
the alto has C# at that point, so the RH is available for the soprano
the top of page 7, the same solutions also apply, as the soprano's F#
is needed only when the alto is on C#.
