Complementing the study of jazz repertoire, they focus on musicianship skills central to the performance of jazz and to working by ear. The aural tests have been carefully devised to enhance listening, analysing and improivsing, while introducing a full range of styles. The quick study is about playing unprepared - in true jazz fashion - and improvising a response to a given opening.
