I’m a bass singer in a church choir; I also play guitar fairly well, and fool around on an electric bass. With training and experience, you get a sense of what the root of a given chord is, in large part in the context of the piece of music as a whole. The most common four chords in the key of C would be C F G Am, but the most common four chords in a song in Am would be Am Dm E C.
