Most organists are reluctant to attempt improvisation because they seem convinced that it must be elaborate and complex. In the hands of masters of the art this may be true; simple improvisation, however, can be within the grasp of most organists. When learned, this skill can be of great use, and it is especially effective as a tool to enhance worship. These lessons make this material as practical as possible, allowing the organist to make direct and immediate application of the art of improvisation to the playing of the church service itself. Lessons include: Improvising a hymn introduction Adding non-harmonic material to a hymn Solo with accompaniment Embellishing the melody Additional improvising of the hymn-tune melody Improvising an introduction Improvising a complete prelude based on a hymn tune
