I know tenor clef to read piano music: add 2 flats, and shift the notes down 2 lines, I think.
Looking at this flute music, the range fits well playing the lines directly as bass clef, but what about the key ?
Trombonist ChuckW seems to have the best answer, add 3 flats. I have played tenor clef before, but want to read the music as written, no shift. I’m not very good at that.
