What makes it more playable?
I changed the key from Db/Gb to Eb/Ab. I took out all repeats except the first strain and redid the countermelody. I left out the grace notes and gave the three note pattern to just the upper woodwinds instead of the tpt. I added new harmony, dynamics, walking bass line and slight melodic variations but the molto marcato is a must throughout unless otherwise indicated in the score and parts.
You can listen to it and take a look at the score at:
I also made a video on YOUTUBE using the music.
