I want to learn to play written music for the e-flat alto, and b-flat tenor saxophones. I have seen many recommendations for using the Rubank Method books to practice. I understand transposing instruments vs. concert pitch, but I find no clear information explaining that the Rubank books are written in anything other than concert pitch.
I've seen where people say that these books are for ALL saxophones (therefore, even C melody too). Since the fingering charts for any key of saxophone call the same fingerings by the same note names, that makes sense for any pitch of instrument.
However, different pitched instruments could not play the music as written at the same time. Is it intended for only a particular instrument pitch to play at a time regardless of real pitch sounded? How should a student with both b-flat and e-flat instruments use the Rubank Method books?
