Here is a very basis singing exercise to practice the first three notes in a major scale (do, re, mi). It will help to look at the tone ladder as you listen and sing the echos. This is especially helpful if you are not sure yet which tones are higher and which are lower. As you go up the ladder, the notes get higher. As you go down the ladder, the notes get lower. Sing the notes in your mind as I sing them, then sing the first note of the echo in your mind before you sing it. This will help you sing it in tune. Practice, practice, practice. It will get easier. If the do, re, mi exercise is easy then move on to the second exercise, so, fa, mi, re, do.
do, re, mi exercise
so, fa, mi, re, do exercise
