If you're looking to learn how to sing like Eva Cassidy, one of the most important things to remember is that her approach to singing was unique and highly emotive. Eva had an uncanny ability to convey deep emotion and meaning in her performances, even when singing covers of other artists' songs.

One of the key aspects of Eva's vocal technique was her use of dynamics - she was equally comfortable singing softly and gently or belting out powerful, emotional phrases. Her phrasing was also highly expressive and she often extended notes or phrases to add emotional weight.

If you're looking to sing songs like Eva Cassidy, start by listening closely to her performances. Pay careful attention to her use of dynamics, phrasing, and emotion, and try to incorporate some of these elements into your own singing.

Another important element of Eva's vocal style was her use of vibrato, which added warmth and depth to her performances. Consider working on your own vibrato technique to add a similar richness to your singing.

In terms of specific songs to study, Eva's covers of classics like "Fields Of Gold," "Somewhere Over The Rainbow," and "Ain't No Sunshine" are all excellent examples of her emotive style and unique vocal approach.
