The jazz musician must learn nomenclature found in the many volumes of repertoire in current circulation. To facilitate the interpretation of and improvisation upon jazz pieces of various styles, an examination and explanation of common practice is necessary. Intervals through the 13th, construction and function of 3, 4, and 5-note chords, common scales and chord sequences, rhythms and song forms will, through dictation exercises, be made a part of the improviser's language, preparing for the application of these elements in Jazz Improvisation, Jazz Chamber Music, and applied courses offered in the jazz minor curriculum.
