I have a question about trombones. I played tenor trombone from 5th grade to 10th grade. I also like to take concert, marching, jazz band and orchestra scores and put them in my Music Creator 5 program on my computer. A couple jazz band scores have trombone 4 as bass trombone. Do I put the bass trombone 1 octave lower than the tenor trombone, or leave it the same? Thank you.
