Write the highest note as an a# and consider it as an added 13#.
Write the upper notes as c-e-bf and interpret it as bitonal (C7 over
csharp).
Ok. If I include the g-sharp I got C7#5 over c#. Wow.
That'd be an option but I meant something different. Of course (as
others have said) it's also depending on the context, that is on the
actual voicing/instrumentation and the general kind of harmony the music
seems to follow.
What I meant is: Consider the (left hand?) c# g# as "c#" without
specifying major/minor and the c e b# as C7. If I imagine this played on
a piano(-like instrument) this could well be an appropriate description
of what it sounds like.
