Hi.
So, I just switched from viola to cello in my school orchestra. I am doing absolutely terrible on the cello. I really tips, so anything that helps even a bit is great.
Thanks.

Tips:
1.) Practice slowly
2.) Practice often
3.) Focus on technique

While the cello is a stringed instrument, it requires a different style of playing when compared to that of the viola. Just keep on trying and you will be rewarded.
