Throughout this thesis you will see the terms songs and music. They will be
used in the same way as in the book Songs in Action, written by Dale T. Griffee,
who defined them as follows: “The word songs refers to pieces of music that have
words, especially popular songs such as those one hears on the radio. By music is
meant instrumental music, for example, symphonic, chamber, easy listening, or solo
instruments such as the organ, flute or guitar” ( p. 3).
