Benjamin Nicholson #4850675. Published by Benjamin Nicholson (A0.924671). A simplified version I created for one of my students. The 2nd cello line (basically a walking bass line) is perfect for the beginner cellist as a melodic exercise for 1st position, and ideal excuse to play with their teacher and good practice in tuning to harmonies. The 1st cello line ideal for the teacher or a more advanced student proficient into 4th position and double stopping.
