Ok, I bought the part on-line and printed it out. The String Bass part is
not 100% the same as the Tuba. In some places, the DB Tacits while the Tuba plays. Less work for me!
Reading the Tuba part all marked up caused me to stop several times when mis-reading the proper bass notes while trying to read the part in octaves, marked up or transposing mentally while not really knowing what register to play the DB part in.
With the actual DB part printed out, it's sooooooooooo much cleaner to read.
I'm all set now
.. and $4.95 poorer..
