Playing the saxophone Bass sax - reading tuba and bass parts

[Tenor Viol]

If I interpret that first bar correctlly (no guarantees!) it's a C clef, so the second line from the top is C, and the two notes would be B(b) and D(b). It seems the accidentals are redundant. I don't see any place before where they were made natural to imply courtesy accidentals.

Yes, the switch to tenor clef happened two bars earlier.

If it's any consolation... that was a challenging piece to play... I don't guarantee that the right notes were played, or in the right order...
