In the process of cleaning up my attic, I discovered a box of music with various tuba studies I used back in college. Among them was a book of studies by Jaroslav Cimera. There are some interesting and unusual etudes in the book. The problem is there seems to be numerous errors e.g. sharps where naturals seem to be called for, notes not quite on line or in a space, missing bar lines. Is there a more recent and hopefully better proof-read edition available? If so, from whom? Thanks for any info.

I have a copy from the late 1950s. When was yours published?
