Dear MarcLarcher. I left out a step.
I put four quarter notes (Snare Drum) in several bars. Then, I wrote ‘tr’ in long-hand, the one that is directly under “Baroque and Classical” This is in the column a little to the left over the Popovers. Thanks for your help. Still looking for help on putting slashes (tremolos) through notation.
