Open a new tab with the score: Cast_thy_burden_upon_the_Lord
You may print this score. It is the one we use.
It is public domain.

Here is where you can go to learn notes. “Cast Thy Burden Upon the Lord” is number 15 of “Elijah.” You can select your voice part and also adjust the speed. This is a really good resource to learn!

Next, listen to a really good recording. Try to sing your part. If you cannot, listen more and try again. Still having trouble? Go back to the note learning.
